What is Ethena?
Ethena issues USDe, a dollar made from crypto and an offsetting futures position instead of cash in a bank. This guide explains how it works, where the yield comes from, who is behind it and what can go wrong, in plain English.
USDe traded at $0.65 on Binance for about 40 minutes on October 10, 2025, while staying within about 0.3% of a dollar on Curve and Uniswap.

These figures do not update live. They are the last values we could verify from published reporting and Ethena governance reports, and they move every day.
Early October 2026. The peak was about $14.8B on October 10, 2025.
Reported annual rate in early October 2026. It was about 3.5% in April 2026.
Fixed total. All remaining investor tokens unlocked on October 5, 2026.
The fee switch passed in September 2026 but only starts when the 14-day average USDe supply crosses this line.
USDe is not a bank deposit. It is not insured by any government scheme, it is not redeemable at a bank, and it can trade below one dollar. sUSDe yield is variable and has ranged from over 60% to under 4%. Nothing on this page is financial advice.
Ethena in 60 seconds
The short version, for people in a hurry.
Ethena is a crypto protocol that issues USDe, a token designed to be worth one US dollar without keeping dollars in a bank.
Most stablecoins, such as USDT and USDC, are backed by cash and short-term government debt held by a company. Ethena took a different route. In its original design, it holds crypto such as ether or bitcoin and, at the same time, opens an equal-sized bet that the same crypto will fall. When the price goes up, the crypto gains and the bet loses the same amount. When the price goes down, the reverse happens. The two cancel, so the dollar value stays roughly flat. Traders call this a delta-neutral position.
That bet is a short perpetual futures position on an exchange. For most of crypto's history, people holding shorts have been paid a regular fee by people holding longs, called the funding rate. Ethena collects that fee, adds staking rewards and interest on its other holdings, and passes most of it to people who stake USDe into sUSDe. That is where the yield comes from.
USDe
The synthetic dollar. Targets $1. Pays nothing by itself. About $4.8B in circulation in October 2026.
sUSDe
What you receive when you stake USDe. Its value in USDe rises as protocol revenue is paid in. Variable, never guaranteed.
ENA
Votes on the protocol's direction. 15 billion maximum supply. A revenue-funded buyback has been approved but has not started.
Five things to remember
- It is a hedged trade, not a bank account. The stability comes from two positions offsetting each other, plus a growing share of plain stablecoins and lending.
- The yield is market income. When traders are bullish and pay to be long, yield is high. When they are not, it shrinks or disappears.
- It depends on centralised exchanges and custodians. The hedges sit on venues such as Binance, Bybit and OKX. The collateral sits with custodians. Both are counterparties.
- It is not like Terra's UST in structure, because every USDe is backed by outside assets rather than a sister token. It shares one trait with UST though: demand follows yield, and supply can leave quickly.
- It has shrunk a lot. Supply fell by about two thirds between October 2025 and April 2026. Redemptions were honoured throughout, which is the important part, but it shows how fast the system can contract.
Deep diveWhy is it called a "synthetic" dollar?
Because nobody is holding a dollar for you. The dollar value is synthesised from other things: an asset that moves, and a derivative that moves the opposite way. Ethena itself avoids the word "stablecoin" for USDe in most of its material and uses "synthetic dollar" instead. The distinction matters legally as well. Laws such as the US GENIUS Act and the EU's MiCA define payment stablecoins as tokens backed one-for-one by cash-like reserves, and USDe does not fit that definition. Ethena's separate token USDtb does.
Deep diveIs USDe still mostly a futures trade in 2026?
Less than you might expect. Ethena's backing is managed dynamically. When funding rates are poor, it moves backing out of the hedged trade and into liquid stablecoins and lending. A governance report for the end of April 2026 showed roughly 57% of backing in liquid stablecoins, 29% in DeFi lending, 13% in the crypto basis trade and under 1% in institutional lending. In hot markets the basis trade share has been far higher. So "what backs USDe" is a question with a different answer each month. The live split is on Ethena's transparency dashboard.

Origins
From a blog post about dust and crust to a multi-billion dollar protocol.
Ethena began as a response to two events: the collapse of Terra's UST in May 2022, and an essay by BitMEX co-founder Arthur Hayes in March 2023.
The problem it set out to solve
Crypto runs on dollar tokens, and the largest ones depend on the banking system. USDT and USDC keep reserves in bank accounts, money market funds and US Treasury bills. That became uncomfortable in March 2023, when Silicon Valley Bank failed and USDC briefly traded below 90 cents because part of its reserves were stuck there. Meanwhile the main attempt at a dollar that did not depend on banks, TerraUSD, had gone to zero the year before and taken about $40 billion of value with it.
"Dust on Crust"
In March 2023, Arthur Hayes published an essay titled Dust on Crust. He proposed a dollar token backed by bitcoin and an equal short position in bitcoin perpetual swaps, issued by an organisation working with derivatives exchanges. No banks, no algorithmic sister token. Ethena's own documentation names this essay as the genesis of the project.
The idea was not new to traders. The "cash and carry" or basis trade, where you hold an asset and short its future to collect the difference, is decades old. What Hayes proposed was to wrap that trade in a token and let anyone hold it as a dollar.
Guy Young builds it
Guy Young had spent roughly a decade in traditional finance, most of it at the investment firm Cerberus Capital Management. He has said the Terra collapse pushed him to leave and work in crypto. After Hayes's essay he assembled a team and founded Ethena Labs in 2023. Two choices set his version apart from the essay: it launched with ether and staked ether rather than bitcoin, which added staking rewards on top of funding, and it kept collateral with off-exchange custodians instead of leaving it on the exchanges, a lesson taken from the failure of FTX.
$6M seed round
Led by Dragonfly, with Deribit, Bybit, OKX, Gemini, Huobi and Arthur Hayes taking part. Several backers were the same exchanges Ethena would later hedge on.
$14M round and public launch
Dragonfly and Hayes's family office Maelstrom co-led a round at a reported $300M valuation. USDe opened to the public on Ethereum on February 19, 2024.
ENA airdrop
After a six-week "shard" points campaign, 750 million ENA (5% of supply) was distributed to early users and the token began trading.
Fastest dollar to $10B
USDe passed $1B within weeks, $3B by mid-2024, and peaked near $14.8B in October 2025, briefly making it the third-largest dollar token.
Deep diveWhat did Young change from the Hayes essay?
Hayes imagined exchanges themselves co-owning the issuer and holding the collateral. Ethena instead became an independent protocol that uses exchanges as venues. Collateral is held with custodians and only "delegated" to exchanges as margin, so that an exchange failure should cost Ethena unsettled profit rather than its principal. Ethena also started with staked ETH, which earned a few percent a year from Ethereum itself, giving the system a cushion in periods when funding went negative. Bitcoin was added as backing in April 2024.
Deep diveWhy was the early reaction so hostile?
USDe launched offering an annualised yield above 25%, less than two years after Terra's Anchor protocol offered about 20% on UST and then collapsed. Many well-known figures in DeFi publicly warned that it looked similar. The criticism was partly about structure (which is in fact different, see the comparison section) and partly about behaviour: a large, yield-seeking deposit base, heavy use of leverage, and a design that had never been through a deep bear market. Ethena responded by publishing custodian attestations, a reserve fund, and later a risk committee of outside firms. Those concerns have not gone away, and this guide covers them in the risks section.

How it works
The hedge, the yield, and what happens when the market turns. Two simulators to try.
USDe holds its value by pairing every asset that can move in price with a position that moves the opposite way.
Step by step: minting a USDe
Redemption runs in reverse: an approved firm returns USDe, Ethena closes the matching short and hands back collateral worth one dollar per token, less costs. This is what anchors the price. If USDe trades at 99 cents on an exchange, a firm can buy it there, redeem it for a dollar of collateral and keep the cent. If it trades at $1.01, firms mint new USDe and sell it.
Only whitelisted participants that pass identity and anti-money-laundering checks, typically market makers and institutions. Everyone else buys and sells USDe on exchanges and in DeFi pools. That means ordinary holders rely on those firms, and on market liquidity, to keep the price at a dollar.
Try it: the delta-neutral hedge
Imagine Ethena takes in one ETH when ETH is $3,000 and shorts one ETH of perpetual futures. Move the price and watch the two legs.
Hedge simulator
Illustrative · ignores fees and fundingA real position also has trading fees, funding payments, margin rules and small gaps between spot and futures prices. The hedge removes price direction. It does not remove those.
Where the yield comes from
The hedged position does not just sit there. It earns, or costs, money in several ways:
- Funding rate. Perpetual futures have no expiry, so exchanges keep them near the spot price with a fee paid between longs and shorts every few hours. When more traders want leveraged long exposure, longs pay shorts. Ethena is short, so it gets paid. When the market is fearful, shorts pay longs and Ethena pays.
- Staking rewards. If the collateral is staked ETH, it earns Ethereum's staking yield, historically around 3%.
- Stablecoin and Treasury income. The part of backing held in liquid stablecoins and in USDtb, which is backed by a tokenised Treasury fund, earns roughly short-term dollar interest.
- Lending. Since 2026 a growing share of backing is lent in over-collateralised DeFi markets and to institutional borrowers such as Maple, Anchorage Digital and Coinbase Asset Management, subject to risk committee approval.
- New basis trades. In 2026 governance approved hedged trades on tokenised gold and, from September 2026, tokenised US equities on Binance.
Reported figures give a sense of the range. Funding on the major perpetual markets averaged about 11% a year in 2024 and about 5% in 2025. sUSDe paid above 60% briefly in March 2024, ran in the mid-teens for much of 2024, ranged between roughly 4% and 15% in 2025, and sat near 3.5% in April 2026. One July 2026 report put the average since January 2024 at 10.9%. Past rates say nothing reliable about future ones.
Try it: funding rate and the reserve fund
This simplified model shows why yield falls as funding falls, and what absorbs losses when income turns negative.
Funding and yield simulator
Illustrative model · not a forecastAssumptions: $4.8B of USDe, a $62M reserve fund (the size reported in April 2026), staking yield on collateral ignored, no protocol fee taken, and no change in the backing mix. In reality Ethena moves backing out of the basis trade when funding is poor, which is why the second slider matters so much.
What happens when funding goes negative?
This is the question most people ask first, and the honest answer has three layers.
- Yield drops to zero first. sUSDe holders do not get charged. The sUSDe exchange rate is designed never to fall because of negative income; holders simply earn nothing for that period.
- The reserve fund pays. Ethena keeps a pool of assets, about $62M in April 2026, held mainly in USDtb. When total income would be negative, the fund covers the difference so that the backing behind USDe is not eaten into.
- The trade gets smaller. If funding is negative, holding USDe is unattractive, so people redeem. Each redemption closes shorts, which removes the selling pressure that was pushing funding down. Ethena can also shift backing into stablecoins itself. The system is meant to shrink in bad conditions, and since October 2025 it has.
If negative funding were deep and long enough to exhaust the reserve fund while the basis trade was still large, the shortfall would come out of USDe's backing, and USDe would be worth less than a dollar. That has not happened. It is the core tail risk of the design.
Deep diveOff-exchange settlement: why the collateral is not on Binance
When FTX failed in 2022, firms that had left assets on the exchange lost access to them. Ethena uses "off-exchange settlement" (OES) providers. Collateral stays in custody accounts with firms such as Copper (its ClearLoop system) and Ceffu, and is only mirrored to exchanges as margin. Profits and losses are settled between the custodian and the exchange on a regular cycle, daily in Copper's case. If an exchange stopped operating, Ethena's exposure should be limited to profit not yet settled, plus the cost and delay of re-opening hedges elsewhere. The collateral itself would remain at the custodian. This moves risk rather than removing it: the custodians are now critical counterparties.
Deep diveCan the short position be liquidated?
A short loses money when the price rises. Normally the collateral gains the same amount, so the account stays balanced. Trouble can arise if the collateral and the contract are not the same asset. Staked ETH can trade at a discount to ETH, for example. If that discount became very large, the margin backing the short could fall short on a particular exchange. Ethena limits this by using low leverage, spreading positions over several venues and capping staked-ETH collateral. The April 2026 backing was dominated by ETH (about 74% of the basis trade) and BTC (about 22%).
Deep diveHow does the sUSDe cooldown work?
Staking USDe into sUSDe is immediate. Unstaking through the protocol is not. For most of Ethena's history there was a seven-day cooldown. In March 2026 governance replaced that with a dynamic cooldown of one, three, five or seven days depending on liquidity conditions, set to one day at activation. You can skip the wait by selling sUSDe on a DEX, but the price you get there depends on market liquidity and can be below its redemption value in a rush.
Deep diveWho keeps the revenue?
Only staked USDe earns. Because a large share of USDe is held unstaked (in exchange accounts, liquidity pools and as collateral), the income earned on all of the backing is concentrated on the staked portion. That is why sUSDe can yield more than the underlying trades do. The rest of protocol revenue has gone to the reserve fund in the past (the allocation is currently set to 0%), to partners and distribution incentives, and to the Ethena Foundation. Ethena reported about $22M of revenue in April 2026, of which around $9.8M went to sUSDe holders and $7M to partner payouts.
The product family
Six tokens, each doing a different job. Pick one to see what it is and who it is for.
USDe
The core product. A token that targets one dollar, backed by a managed portfolio: hedged crypto positions, liquid stablecoins, lending and tokenised real-world assets. It pays no yield by itself.
Used for: trading pairs and margin collateral on exchanges including Binance, Bybit, Deribit and MEXC, liquidity pools on Curve and Uniswap, collateral on Aave and other lenders, and as the base for sUSDe.
Know this: USDe is issued by an offshore entity and is not available through Ethena's app to US users or, since 2025, to users in the EU and EEA.
sUSDe
Stake USDe and you receive sUSDe. You do not get more tokens over time. Instead each sUSDe becomes redeemable for more USDe as revenue is paid into the staking contract. Rewards are calculated from actual protocol income and dripped in over eight-hour periods.
Used for: holding as a savings position, as collateral on Aave and Morpho, and split into fixed and variable yield on Pendle.
Know this: regulators in Germany treated sUSDe as a possible unregistered security in 2025. The yield has no floor other than zero.
USDtb
A conventional stablecoin from the Ethena ecosystem. It is backed by cash and by BlackRock's tokenised Treasury fund BUIDL, which is issued through Securitize. Reports in 2026 put more than 90% of reserves in BUIDL.
Used for: a place for USDe's backing to sit when futures funding is unattractive, the main asset of the reserve fund, and the reserve asset behind white-label stablecoins such as jupUSD and USDm.
Know this: in July 2025 Ethena and Anchorage announced that the federally chartered crypto bank would issue USDtb in the United States, described at the time as the first stablecoin issued under GENIUS Act standards. USDtb does not pay yield to holders.
iUSDe
The same economics as sUSDe inside a wrapper that can enforce transfer restrictions. It exists so that regulated firms, such as asset managers, funds and prime brokers, can hold the product within their compliance rules.
Know this: part of the $100M raised from investors including Franklin Templeton and Fidelity-affiliated F-Prime in December 2024 was earmarked for building iUSDe. Public data on how much iUSDe exists is limited.
ENA
ENA holders elect the risk committee and vote on matters such as which assets may back USDe and how revenue is used. It is not a claim on USDe's backing and it does not stabilise USDe.
Used for: governance, staking into sENA, and unlocking higher tiers in the Ethena Pay app by locking ENA.
Know this: ENA is a volatile asset. It traded above $1.20 in late 2024 and near $0.22 in early October 2026.
sENA
The liquid receipt for staked ENA. It was introduced so that ENA holders could be rewarded by ecosystem projects. Apps built around Ethena have allocated part of their own token supplies to sENA holders; for example, sENA holders could claim BASED tokens in April 2026.
Know this: earlier proposals imagined a share of protocol revenue flowing to sENA holders. The mechanism approved in September 2026 instead directs revenue to programmatic ENA buybacks once supply thresholds are met.
White-label dollars built on Ethena
Since late 2025 Ethena has also run a "stablecoin as a service" business called Ethena Whitelabel. A partner chooses the name and controls distribution. Ethena handles issuance, reserves, custody and redemptions. The partner keeps part of the reserve income that would otherwise go to Tether or Circle.
jupUSD
Launched with the exchange aggregator Jupiter. Backed by USDtb and USDC at launch.
USDm
The native dollar of the MegaETH network, designed to subsidise its sequencer fees. Backed by USDtb and USDC at launch.
suiUSDe
A Sui-native dollar backed by USDe and USDC. A companion BUIDL-backed token, USDi, was announced alongside it in 2025.
ether.fi USD
ether.fi said on October 6, 2026 it will issue its own dollar on the platform. Launch date and terms were not disclosed.
White-label supply passed $600M in April 2026, according to Ethena's governance reporting.
ENA tokenomics
Supply, who got what, when it unlocks, and how the approved buyback is meant to work.
ENA has a fixed maximum supply of 15 billion tokens. As of October 2026 most of it is unlocked, and a revenue-funded buyback has been voted in but has not started.
Percentages follow Ethena's published allocation. The ecosystem share includes the 2% (300M ENA) distributed through Binance Launchpool at launch and the airdrop seasons.
The unlock story in five dates
April 2, 2024: token launch
ENA begins trading. 750M ENA is airdropped to early users. Team and investor tokens are locked.
Spring 2025: one-year cliff
Team and investor allocations pass a one-year cliff, at which 25% unlocks, followed by monthly vesting planned to run for three more years.
August 2026: investor buyout
The Ethena Foundation buys the remaining locked tokens of large seed investors who had been selling. Sizes and names were not disclosed. Investors who had not sold were offered the same deal at their original price and none accepted.
October 5, 2026: investor vesting ends
Instead of monthly releases, all remaining investor tokens unlock at once: roughly 1.41 billion ENA. From here only team, foundation and ecosystem tokens remain locked.
Through spring 2028: team and foundation
Team and foundation tokens keep vesting monthly on the original schedule, at roughly 134M ENA a month according to one tracker, ending around March to April 2028.
Figures disagree between sources. Ethena's own chart says about 12% of supply remains locked after October 5; the token tracker Tokenomist computes about 22.8% from the published schedule, and circulating supply estimates in October 2026 range from roughly 11 billion to 13.4 billion. StablecoinX's roughly 3 billion ENA sits under a separate lock-up described in its SEC filings.
How the fee switch scales with USDe supply
The vote that closed on September 2, 2026 (about 17.8M ENA in favour, none against) set a ladder. As the 14-day average USDe supply passes each step, a larger share of gross protocol revenue goes to the Foundation, and 95% of that is used to buy ENA on the market. Below $7.5B, nothing happens.
The dollar figure uses the same 6% revenue yield that the Ethena Foundation used in its own illustration ($22.5M a year at $7.5B, $60M at $10B, $135M at $15B). It shows how the mechanism works. It is not a forecast of supply, revenue or price. Sources differ slightly on the top two steps.
What ENA does, and does not do
It does
- Elect the Risk Committee every six months
- Vote on backing assets, revenue use and major protocol changes
- Stake into sENA for ecosystem rewards
- Unlock Pro and VIP tiers in Ethena Pay when locked
- Stand to benefit from buybacks if USDe grows past $7.5B
It does not
- Back or stabilise USDe in any way
- Give a legal claim on reserves or company equity
- Pay a dividend today
- Have a guaranteed buyback: the trigger depends on supply nearly doubling from April 2026 lows
Deep diveThe long road to the fee switch
The idea of sharing revenue with ENA holders was first put forward in a governance proposal by the trading firm Wintermute in November 2024. The Risk Committee then set conditions tied to USDe supply, revenue and exchange adoption, which were reported as met in late 2025. Some outlets subsequently described the switch as active in early 2026, but no distribution mechanism was confirmed. The clear, final design came on August 27, 2026, when the Foundation proposed a buyback ladder tied to USDe supply. It passed on September 2. At the same time Ethena ended the ENA incentives that had been paid to USDe holders (they stopped on September 30, 2026), so ENA holders are now waiting on organic growth to reach the $7.5B trigger.
Deep diveStablecoinX: a public company that holds ENA
StablecoinX is a "digital asset treasury" company formed in July 2025 to accumulate ENA, initially with a $360M plan that later grew to a reported $890M through further private financing. The Ethena Foundation contributed tokens to the deal. The cash raised was used to buy locked ENA from a Foundation subsidiary, which in turn bought ENA on the open market in 2025. After merging with the blank-cheque company TLGY, StablecoinX began trading on Nasdaq on June 26, 2026 under the ticker USDE, led by chief executive Edward Chen. It held about 3.03 billion ENA, close to 20% of total supply, valued at roughly $275M at the time. Its shares are equity in a company, not USDe, despite the ticker.
Deep diveWho owns the protocol? The Master Framework Agreement
A common question about token projects is whether value ends up with the token or with the private company's shareholders. In August 2026 the Foundation and Ethena Labs said they had agreed in principle on a Master Framework Agreement under which substantially all material intellectual property would be assigned or exclusively licensed to the Foundation, and economic benefits, including proceeds from any future sale of the business, would flow to the Foundation and its ecosystem rather than to Labs equity holders. Publication of the framework was expected in October 2026. We could not confirm at the time of writing that the final document had been published.
People and organisations
Who built Ethena, who funds it, who holds the assets and who checks the risk.
Guy Young
Founder and chief executive, Ethena Labs
Guy Young is the person most responsible for turning a trader's thought experiment into one of the largest dollar tokens in crypto. He keeps a low personal profile. His nationality, education and where he lives are not part of the public record he has chosen to share, and this guide does not speculate.
Before crypto
Young spent close to ten years in traditional finance across investment banking, hedge funds and private equity. About six of those, from around 2016 to 2022, were at Cerberus Capital Management, a large US private investment firm. Biographical sources say he rose to head of principal investments at a Cerberus affiliate, worked on the firm's expansion in Australia, and covered banking, specialty finance, insurance and financial technology. That background in credit and bank balance sheets shows in how Ethena is built: it looks more like a structured finance product with custody and counterparty arrangements than like a typical DeFi protocol.
Why he left
By his own account in interviews, the collapse of Terra's UST in May 2022 convinced him that crypto still lacked a scalable dollar that did not depend on banks, and he left Cerberus to work on it. Arthur Hayes's March 2023 essay supplied the design. Young began building soon afterwards, and Hayes became an early investor and adviser.
"We're trying to create something that exists outside of the banking system."Guy Young to Axios, July 2023, as reported by The Block
How he runs it
Profiles describe Young as pragmatic rather than ideological. Ethena relies openly on centralised exchanges and custodians, which purists dislike, and he has defended that as the only way to reach meaningful scale. He has also steered the project toward traditional finance: the BlackRock-linked USDtb, the institutional iUSDe wrapper, a US-chartered bank as issuer, and investors such as Franklin Templeton and F-Prime.
Under pressure
Young is the public voice in every stress event. After the Bybit hack in February 2025 Ethena set out its exposure publicly the same day. After USDe traded at $0.65 on Binance on October 10, 2025 he argued it should not be called a depeg, because the price dislocation was confined to one venue using its own order book as an oracle while redemptions continued normally elsewhere. In 2026, with supply down by two thirds, he fronted the shift into lending, equity basis trades and the Ethena Pay consumer app.
"This is the most significant expansion of USDe's funding mechanism since we started."Guy Young on tokenised equity basis trades, The Block, September 25, 2026
Recognition and criticism
CoinDesk named him to its Most Influential list for 2025, crediting him with taking Ethena to roughly $15B in about two years. Critics point to the same facts from the other side: the growth was powered by incentives and leverage, and much of it reversed. A fair summary is that Young built a product that has so far done what it said under stress, and that its long-term size is still an open question.

Custodians and venues
Custody and settlement
Copper (ClearLoop) and Ceffu are the off-exchange settlement providers named in Ethena's documentation. Anchorage Digital issues USDtb. Kraken Custody was added in January 2026 with monthly attestations and weekly proof of reserves, and BitGo launched an institutional savings integration in April 2026.
Exchanges
Hedges are spread across large derivatives venues. Binance, Bybit, OKX, Deribit and others have been used, and several are also investors. Binance, Bybit, Deribit and MEXC accept USDe as margin collateral. The current split by venue is published on Ethena's dashboard.
Ecosystem and integrations
Where USDe is used, and the apps built around it.
USDe's growth came from being useful in two places at once: as collateral on centralised exchanges, and as a building block in DeFi.
DeFi
Aave
The largest home for sUSDe and USDe collateral. Ethena-related deposits on Aave were about $2.6B at the end of March 2026 and about $540M a month later, after the April 2026 unwind.
Pendle
Splits sUSDe into a fixed-rate "principal token" and a variable "yield token". Ethena assets on Pendle fell from $1.2B to about $540M over April 2026.
Morpho, Compound, Spark
Morpho held about $226M in April 2026. Compound V3 added USDe collateral in March 2026. Sky's Spark approved a direct allocation of up to $1.1B to USDe and sUSDe in January 2026.
Curve, Uniswap, Fluid
The main on-chain pools where USDe trades against USDC and USDT. During the October 2025 crash about $2B was redeemed in a day while these pools stayed within roughly 0.3% of a dollar.
Strata
Splits USDe yield into senior and junior tranches. Its pool held about $250M in March 2026.
LayerZero
USDe, sUSDe and ENA move between chains using LayerZero's token standard. The bridge was paused and then hardened during the April 2026 rsETH incident.
Apps built on USDe
Ethereal
A trading venue that uses USDe as margin. It held around $40M to $50M of margin in spring 2026 and opened a prediction market alpha in April 2026.
HyENA
A USDe-margined perpetuals market built on Hyperliquid's infrastructure. Cumulative volume had reached about $3.6B by the end of April 2026.
Ethena Pay
A self-custodial money app on Avalanche, in beta since September 1, 2026 in about 48 countries, not including the US or EU at launch. Balances are held in USDe with tiered rates and a card that pays cashback in AVAX.
Exchanges and distribution
- Binance listed USDe for spot trading on September 9, 2025, when supply was above $12B, and accepts it as futures collateral. Since September 2026 it is also the first venue for Ethena's tokenised equity basis trade.
- Bybit was the first large exchange to integrate USDe as collateral in 2024, and runs a Mantle vault built on sUSDe.
- Kraken became the first US exchange to offer USDe rewards in April 2026.
- Telegram and TON: a TON version, tsUSDe, launched in 2025 with extra rewards paid by the TON Foundation.
- TRON: USDe and sUSDe went live on TRON on September 11, 2026 through Stargate, with minting and redemption still on Ethereum.
- Wallet infrastructure: integrations with Privy and WalletConnect Pay were announced in March 2026.
Deep diveWhat happened to Converge?
In March 2025 Ethena and the tokenisation firm Securitize announced Converge, a blockchain meant to host both open DeFi and permissioned institutional products, with USDe and USDtb as gas tokens and ENA staked to secure it. In April 2025 the partners said it would use Arbitrum and Celestia technology and targeted a mainnet in the second quarter of 2025. That date passed. In December 2025 Terminal Finance, an exchange built to launch on Converge, shut down and said the chain had been "indefinitely postponed". We found no evidence of a Converge mainnet as of October 2026. Ethena's current roadmap talks instead about ENA and sUSDe restaking to secure cross-chain transfers, with an "Ethena Chain" to follow. Treat any chain plans as unconfirmed until they ship.
Deep diveAave "liquid leverage" and why it matters
A popular strategy in 2025 was to deposit sUSDe or Pendle principal tokens on Aave, borrow stablecoins against them, buy more sUSDe and repeat. This "looping" multiplies yield when sUSDe pays more than the borrowing rate, and Ethena ran a campaign with Aave that rewarded it. It also means a large part of USDe demand was leveraged. When yields fell below borrowing costs in late 2025 and 2026, the loops unwound and supply fell with them. See the risks section.
Roadmap and what comes next
What Ethena says it is working on, and the open questions. No predictions.
After a year of contraction, Ethena's stated plan is to rely less on crypto funding rates and less on token incentives, and more on new yield sources and its own distribution.
Beyond the crypto basis trade
Hedged trades on tokenised US equities started on Binance in September 2026, following approval of tokenised gold (PAXG, XAUT) as backing earlier in the year. Ethena says equity perpetuals had about $2.9B of open interest on Binance. The six-month average equity basis was about 3.6% a year.
Lending as a backing asset
Over-collateralised loans to institutions through Maple, Anchorage Digital and Coinbase Asset Management, plus DeFi lending, which was already 29% of backing in April 2026.
Ethena Pay
Wider country coverage, including a planned expansion to the US, EU, Canada, Taiwan and South Korea subject to regulation.
White-label dollars
More partner stablecoins after jupUSD, USDm and suiUSDe. ether.fi USD was announced in October 2026.
Restaking and a chain
Generalised restaking of ENA and sUSDe, first to secure cross-chain USDe transfers through LayerZero's verifier network, with a dedicated chain to follow. No dates confirmed.
ENA buybacks
Start only when the 14-day average USDe supply exceeds $7.5B. In early October 2026 supply was about $4.8B.
Open questions
- Can USDe grow without incentives? ENA rewards for USDe holders ended on September 30, 2026. Demand now depends on yield and usefulness alone.
- Is the yield competitive? At 4% to 5%, sUSDe pays about what tokenised Treasury funds pay, with more complex risk. That gap in risk for similar reward is the main reason money left in 2026.
- Will US law allow yield-bearing dollars? The GENIUS Act bars regulated payment stablecoin issuers from paying interest. USDe sits outside that framework. Whether lawmakers leave it there is undecided.
- Do the new trades add new risks? Tokenised equities bring issuer, market-hours and legal risks that crypto perpetuals do not have.
In September 2026 Standard Chartered began research coverage of Ethena and published supply and price targets for 2028. Ethena has stated its own long-term supply ambitions. We mention that these exist because they are news, but we do not repeat the numbers as expectations. Forecasts for a product that lost two thirds of its supply in six months deserve caution in both directions.
USDe compared
How USDe stacks up against the dollar tokens people already know, including the one that failed.
| USDe | USDT | USDC | USDS / DAI | UST (failed 2022) | |
|---|---|---|---|---|---|
| Issuer | Ethena (offshore entity; protocol by Ethena Labs) | Tether | Circle | Sky, formerly MakerDAO | Terraform Labs |
| What backs it | A managed mix: hedged crypto, stablecoins, lending, tokenised assets | Mostly US Treasury bills and cash equivalents, plus some other assets | Cash and short-dated Treasuries in regulated funds | Over-collateralised crypto loans, stablecoins and real-world assets | Nothing external. Convertible into the sister token LUNA |
| How the peg holds | Redemption for $1 of backing by whitelisted firms | Redemption for dollars by verified customers | Redemption for dollars by verified customers | Over-collateralisation, liquidations and a USDC swap module | Mint and burn arbitrage against LUNA |
| Yield to holders | None on USDe. Variable on sUSDe, from protocol income | None | None from issuer; platforms may pay rewards | Savings rate set by governance (sUSDS) | About 20% from Anchor, heavily subsidised |
| Main dependency | Derivatives exchanges, custodians, funding rates | Banks, custodians, the issuer | Banks, custodians, the issuer | Collateral quality, governance, USDC | Confidence in LUNA's price |
| US and EU status | Outside GENIUS and MiCA. Withdrawn from the EU in 2025 | Not MiCA-authorised; Tether has a separate US-focused token | MiCA-authorised and aligned with GENIUS | Decentralised issuer, outside both regimes | Collapsed; founder pleaded guilty to fraud in 2025 |
| Worst moment so far | $0.65 on Binance for about 40 minutes in Oct 2025, near $1 elsewhere. Supply fell from $14.8B to under $4B over six months with redemptions honoured | Brief dips to about $0.95 in 2022 | About $0.87 in March 2023 during the SVB failure | DAI followed USDC down in March 2023 | Fell to near zero in May 2022. About $40B lost across UST and LUNA |
| Can holders be frozen? | Ethena can block addresses from minting and staking | Yes | Yes | DAI no; USDS is upgradeable and can support freezing | No |
Scroll the table sideways on small screens. Descriptions are simplified. Reserve mixes and legal status change over time.
Is USDe "another UST"?
This comparison has followed Ethena since launch. It deserves a careful answer rather than a slogan from either side.
Why it is not like UST
- It is backed by outside assets. Every USDe has roughly a dollar of ETH, BTC, stablecoins or loans behind it. UST was backed only by the right to mint LUNA, whose value depended on faith in UST.
- There is no death spiral loop. Redeeming USDe does not print ENA. ENA could go to zero and USDe's backing would be unchanged.
- The yield is earned. sUSDe pays out what the positions actually made. Anchor's 20% was a fixed promise topped up from a subsidy pot that was running out.
- It has shrunk in an orderly way. About $11B left between October 2025 and April 2026. Attested backing stayed above 100% throughout, and redemptions were paid at a dollar.
Where the comparison has a point
- Demand is yield-driven. Much of the money came for the return, and left when the return fell. A dollar token that people hold only for yield has a fragile user base.
- Leverage amplified it. Looping on Aave and Pendle inflated supply on the way up and accelerated the fall.
- It is complex. Most holders cannot check a derivatives book spread across exchanges and custodians. They rely on attestations and dashboards.
- It is untested in one scenario. A long period of sharply negative funding while the basis trade is still large has not occurred.
The fair conclusion: USDe's failure mode is different from UST's. UST failed because its backing was circular. USDe's risks sit in counterparties, funding and liquidity. Those are real, and they are covered next, but they are a different category of risk.
Wallets
Where to keep ENA, USDe and sUSDe. Filter by type or chain.
ENA, USDe and sUSDe are standard tokens. On Ethereum they are ERC-20s, so any Ethereum wallet can hold them. Versions exist on Solana, TON, TRON and several other chains.
Showing all 12 options
MetaMask
The most widely used Ethereum wallet. Holds ENA, USDe and sUSDe on Ethereum and other EVM chains. Works with Ethena's app, Aave, Pendle and Curve.
Rabby
An EVM wallet that previews what a transaction will do before you sign, which helps when using DeFi apps.
Ledger
Keeps keys on a physical device. Supports ERC-20 tokens such as ENA and USDe, and can be paired with MetaMask or Rabby.
Trezor
Open-source hardware wallet with ERC-20 support. Pair with a software wallet for DeFi.
Safe
A smart-contract wallet that needs several approvals per transaction. Common for teams and larger holdings.
Phantom
Popular on Solana, where USDe and jupUSD circulate, with support for Ethereum and Base.
Trust Wallet
Multi-chain mobile wallet covering Ethereum, BNB Chain, Solana and TRON.
OKX Wallet
Multi-chain wallet with a built-in DEX aggregator.
Tonkeeper
A self-custody TON wallet for the TON version of staked USDe (tsUSDe).
TronLink
The main TRON wallet. USDe and sUSDe went live on TRON in September 2026.
Ethena Pay
Ethena's own self-custodial money app on Avalanche. Holds USDe as a spending balance. Not available in the US or EU at launch.
Exchange account
Leaving tokens on Binance, Bybit, Kraken or similar. Convenient, but the exchange holds the keys and you take its risk.
Write your recovery phrase on paper and never type it into a website. Check token contract addresses against Ethena's documentation before adding a token, because fake USDe and ENA tokens exist. When bridging between chains, use the official routes listed by Ethena. We have not tested every wallet with every chain version; confirm support before you send funds.
Deep diveSelf-custody or exchange?
On an exchange you can trade quickly and may be able to use USDe as margin, but you depend on the exchange being solvent and on its internal pricing, which mattered a great deal on October 10, 2025. In your own wallet you control the keys and can use DeFi, but mistakes are yours and cannot be reversed. Many people split holdings between the two.
Where and how to buy
Getting ENA, getting USDe, and staking to sUSDe, step by step. Not a recommendation to do any of it.
Buying ENA is buying a volatile governance token. Holding USDe or sUSDe is holding a synthetic dollar that is not insured and can lose value. Availability depends on where you live: Ethena's own app is closed to US users and to the EU and EEA, and exchanges restrict products by country.
Where they trade
Centralised exchanges
Binance, Bybit, OKX, Coinbase, Kraken, KuCoin, Bitget, Gate, MEXC and HTX have listed ENA. Check your own country's version of the exchange.
Centralised exchanges
Binance (since September 2025), Bybit, Kraken, HTX and others list USDe against USDT or USDC. Binance said in October 2026 it would stop USDe trading for users in Brazil.
Decentralised exchanges
Curve, Uniswap and Fluid on Ethereum hold the deepest USDe pools. Aggregators such as CoW Swap, 1inch or Jupiter (on Solana) route trades across them.
Buying ENA or USDe on an exchange
Choose a regulated exchange that serves your country
Confirm that it lists the token you want for your region. Listings differ between, for example, Binance's global site and its local entities.
Create and verify an account
You will need identity documents. Turn on two-factor authentication with an authenticator app rather than SMS.
Deposit funds
Bank transfer is usually cheapest. Cards are faster and cost more. You can also deposit a stablecoin you already own.
Place the order
Search for ENA or USDe. A limit order lets you set the price. For USDe, anything far from $1.00 is a warning sign about that venue's liquidity, not a bargain to chase blindly.
Decide where to keep it
Leaving tokens on the exchange is simple but means trusting the exchange. Withdrawing to your own wallet gives you control and responsibility. Send a small test amount first and double-check the network: ENA and USDe are ERC-20 tokens on Ethereum, with versions on other chains.
Getting sUSDe
Hold USDe in a self-custody wallet
Plus a little ETH to pay network fees if you are on Ethereum.
Either stake in Ethena's app…
At app.ethena.fi, if your jurisdiction is permitted, connect your wallet and stake USDe. You receive sUSDe at the current exchange rate. Type the address yourself or use a bookmark; fake Ethena sites are a common phishing lure.
…or buy sUSDe on a DEX
sUSDe trades on Curve and Uniswap. You pay the market price, which reflects accrued yield.
Understand the exit
Unstaking in the app starts a cooldown of one to seven days before you can withdraw USDe. Selling sUSDe on a DEX is instant but may be at a discount in stressed markets.
Deep diveCan I mint USDe directly from Ethena?
Almost certainly not. Minting and redeeming directly against the protocol is limited to whitelisted counterparties that pass KYC and AML checks, and it is aimed at firms dealing in size. Everyone else uses the secondary market. This is normal for stablecoins (USDT and USDC work the same way for most people) but it is worth knowing that your exit is a market sale, not a redemption.
Deep diveFees and tax
Expect exchange trading fees, a withdrawal fee, and network fees for any on-chain step. Ethereum fees were very low in October 2026 but can spike. In many countries swapping one token for another, staking, and receiving yield can each be taxable events. Rules vary widely, so check your local guidance or ask a qualified adviser.
Risks and criticisms
The long, frank part. If you only read one section, read this one.
USDe is a financial product with moving parts. Each part can fail. None of the protections around it amount to a guarantee.
USDe and sUSDe are not bank deposits. There is no deposit insurance, no lender of last resort and no legal promise that you personally can redeem at a dollar. The yield is compensation for taking the risks below. If you do not understand them, the yield is not free money you have found; it is a price you have not yet seen.
1. Funding risk
Core riskThe basis trade earns only when longs pay shorts. Funding averaged around 11% in 2024, around 5% in 2025, and went negative for stretches, including after the October 2025 crash. If funding is negative, the hedged portion of the backing loses money each day. The reserve fund (about $62M in April 2026, or a little over 1% of supply) is the buffer. A deep, sustained negative period with a large basis book could exhaust it, and the loss would then fall on USDe's backing.
What reduces it: Ethena can and does rotate into stablecoins and lending. By April 2026 only about 13% of backing was in the crypto basis trade. What does not go away: rotation takes time, and it lowers yield, which drives redemptions.
2. Exchange counterparty risk
Core riskThe short positions live on centralised exchanges. If one fails, freezes or is hacked, Ethena could lose unsettled profits on that venue and would be left unhedged on that portion until it re-opened positions elsewhere, possibly in a chaotic market. Bybit's $1.4B hack in February 2025 was a live test: Ethena reported under $30M of exposure, covered by the reserve fund, and no loss of collateral. A failure of a larger venue during a crash would be a harder test.
3. Custodian risk
Core riskKeeping collateral off exchanges means keeping it with custodians such as Copper and Ceffu. Their solvency, security and legal segregation of client assets are critical. Ceffu is Binance's affiliated custodian, so Binance-related risk appears on both the exchange and custody side. Custodian attestations are published, but an attestation is a snapshot by a third party, not a full audit of the whole system.
4. Liquidity and redemption risk
Core riskOnly whitelisted firms can redeem. Everyone else exits through markets. On October 10, 2025, USDe traded at $0.65 on Binance for about 40 minutes because the order book thinned and the exchange's systems treated that price as real. Anyone forced to sell there, or liquidated there, took a real loss even though on-chain pools were within about 0.3% of a dollar. Binance later paid about $283M in compensation across affected assets, but that was the exchange's choice, not a right.
sUSDe adds a cooldown before unstaking. In a rush, sUSDe can trade below its redemption value.
5. Leverage and looping
Core riskA large share of USDe demand in 2025 came from borrowing against sUSDe or Pendle tokens on Aave to buy more. This made supply look sturdier than it was. When sUSDe yield dropped below stablecoin borrowing rates, loopers unwound. The April 2026 episode showed the speed: after an unrelated exploit, Ethena-related deposits on Aave fell from $2.6B to $0.54B in a month and USDe supply fell by about a third. Looped users also face liquidation if sUSDe's market price dips, and the lending protocols themselves depend on oracles pricing USDe correctly.
6. Collateral and backing-asset risk
SignificantStaked ETH can trade below ETH. Stablecoins held as backing (USDC, USDT, USDtb) carry their own issuer and bank risks, and by 2026 they are the majority of backing. DeFi lending carries smart contract and bad-debt risk. Institutional lending carries borrower default risk, even when over-collateralised. Tokenised equities and gold add issuer and legal risk. As Ethena diversifies its income, it is also diversifying the list of things that can go wrong.
7. Regulatory risk
SignificantGermany's BaFin barred Ethena GmbH from offering USDe in March 2025, citing deficiencies under MiCA and raising the question of whether sUSDe was an unregistered security. Ethena withdrew its EU application and wound up the German entity by agreement, with a 42-day redemption window that closed on August 6, 2025. In the US, the GENIUS Act of July 2025 created rules for payment stablecoins and banned issuers from paying interest. USDe is positioned outside that law. A future law or regulator could decide a yield-bearing synthetic dollar belongs inside a regime it cannot satisfy, or restrict exchanges from offering it.
8. Centralisation and operational risk
SignificantEthena Labs runs the hedging system off-chain. Holders cannot verify trades in real time and rely on dashboards, attestations and the Risk Committee. Mint and redeem contracts are controlled by multisignature keys with limits per block. Ethena's entities can restrict addresses. This is a trusted, company-operated system with on-chain tokens, not a trustless protocol.
9. Concentration
SignificantA handful of exchanges carry the hedges, a handful of custodians hold the assets, and a handful of DeFi venues (chiefly Aave and Pendle) held much of the demand. ENA ownership is also concentrated: StablecoinX alone holds about 20% of supply, and governance votes have passed with small turnout (the fee switch vote drew 88 voting addresses).
10. Smart contract and bridge risk
SignificantThe token, staking and mint contracts have been audited, which lowers but does not remove the chance of bugs. USDe on other chains depends on LayerZero bridging. In April 2026 Ethena paused its bridge as a precaution during the rsETH incident and raised the number of independent verifiers required from two to four.
11. ENA-specific risk
Token holdersENA's value depends on Ethena's growth and on governance decisions. The buyback is conditional. ENA fell from above $1.20 in late 2024 to around $0.22 in October 2026. About 1.41B tokens unlocked on a single day in October 2026. None of the protections for USDe apply to ENA.
What critics say
- "The yield does not pay for the risk." At 4% to 5%, sUSDe pays roughly what a tokenised Treasury fund pays, while carrying exchange, custodian and funding risk on top.
- "It only works in bull markets." Supporters reply that it has survived two sharp contractions with redemptions intact. Critics reply that surviving by shrinking 70% is not the same as working.
- "Growth was bought." Points campaigns, ENA incentives and leverage programmes drove much of the 2024 to 2025 expansion. With incentives ended, 2026 and 2027 will show what organic demand looks like.
- "It is a hedge fund in a token." Largely accurate as a description. Whether that is a criticism depends on whether holders understand that is what they own.
- "It increases systemic risk." A multi-billion short book concentrated on a few exchanges, used as collateral across DeFi, links the fortunes of many platforms.
What Ethena points to in response
Weekly proof of reserves and monthly custodian attestations; attested backing between about 101.1% and 101.6% through March and April 2026; redemptions honoured during every stress event so far; the reserve fund; an elected outside Risk Committee; and a backing mix that adapts to conditions. These are meaningful. They reduce risk. They do not turn USDe into cash.
Stress-test history
What actually happened to USDe in each major market shock.
Theory is one thing. Here is the record, including the parts that are uncomfortable for both fans and critics.
| When | Shock | What happened to USDe | Lesson |
|---|---|---|---|
| April 2024 | Sharp sell-off weeks after launch, on Middle East tensions | Around $100M was redeemed. Reports put USDe within about 0.2% of a dollar. | First proof that redemptions worked under pressure, at small scale. |
| Mid to late 2024 | Funding rates compress; some weeks slightly negative | Supply slid from above $3B to the mid $2B range. Monthly revenue was reported to have fallen below $6M in September 2024. | When yield falls, money leaves. The system shrank and then regrew when funding recovered. |
| Feb 21, 2025 | Bybit hacked for about $1.4B | Ethena reported under $30M of exposure in unsettled profit, covered by the reserve fund. Collateral was off-exchange and unaffected. | Off-exchange custody did its job in a real exchange incident. |
| Mar to Aug 2025 | BaFin bars the German entity | No market stress. Ethena exited the EU and EEA and completed a supervised redemption process. | Regulatory risk is real and can close whole regions. |
| Oct 10 to 11, 2025 | Largest liquidation event in crypto history, roughly $19B to $20B | USDe printed $0.65 on Binance for about 40 minutes. On Curve, Uniswap and Fluid it stayed within about 0.3%. Around $2B was redeemed in 24 hours. Supply went from $14.8B to $12.6B in two days. | The protocol stayed solvent, but a venue's price can break badly, and people on that venue were hurt. |
| Oct 2025 to Mar 2026 | Deleveraging and low funding | Supply fell to about $8.5B within weeks and to about $5.9B by March 2026 as looped positions unwound. | Leverage-driven demand reverses quickly. |
| Apr 18 to 30, 2026 | KelpDAO rsETH exploit shakes DeFi lending | Ethena had no direct exposure, but about $1.6B was redeemed as users pulled out of Aave. Supply fell to $3.9B. Attested backing stayed near 101.6% and the reserve fund was not drawn. | Contagion can arrive from somewhere else entirely. |
| Sep 22, 2026 | Brief dislocation on Binance | USDe was reported to have dipped to about $0.984 on Binance while on-chain pools stayed within 0.3%. | After the 2025 fixes, the venue gap was far smaller, though not zero. |
October 10, 2025 in detail
On Friday, October 10, 2025, a tariff announcement by the US president set off a violent sell-off. Bitcoin fell around 13% and ether more than 16% within the day. On Binance, three tokens used as margin collateral lost their link to fair value: USDe, the staked-SOL token BNSOL and the staked-ETH token WBETH. Binance later said the worst dislocations came between 21:36 and 22:16 UTC.
USDe touched about $0.65 there. The reasons, as later described by Ethena, Binance and independent analysts: Binance valued USDe collateral using its own order book rather than an external reference; market makers had pulled back; deposits and withdrawals were impaired, so arbitrage firms could not move USDe to the exchange or redeem it fast enough; and automatic liquidations sold more USDe into the thin book.
Elsewhere, mint and redeem stayed open and USDe remained overcollateralised. Guy Young argued it was not a depeg of USDe itself. That is defensible in a technical sense and little comfort to anyone liquidated on Binance.
What changed afterwards
- Binance paid about $283M to affected users and changed its pricing: it added each asset's redemption value to its index and put a soft price floor into the USDe reference index.
- Ethena added custody and attestation partners, including Kraken Custody in January 2026 with weekly proof of reserves.
- Legal claims against Binance over the crash were reported in February 2026.
- Ethena's backing moved steadily away from perpetuals, and in March 2026 the sUSDe cooldown was made dynamic.
- The episode became the "market peak" reference date in Ethena's own 2026 investor buyout terms.
Myths vs facts
Common claims, checked.
USDe is an algorithmic stablecoin like UST.
USDe is backed by outside assets: hedged crypto, stablecoins and loans. UST was backed by a sister token. The risks are real but different: counterparties, funding and liquidity, not a circular mint-and-burn loop.
USDe is a decentralised stablecoin.
The tokens are on-chain, but the hedging runs through a company, centralised exchanges and custodians, and only whitelisted firms can mint or redeem. Ethena itself calls it a synthetic dollar.
sUSDe yield is guaranteed, like interest.
It is a share of whatever the backing earns. It has been above 60% and below 4%. It can be zero. Nobody owes it to you.
If funding turns negative, USDe breaks.
Not immediately. Yield stops first, the reserve fund absorbs losses, and backing is rotated into stablecoins. A deep, prolonged negative period with a large basis book is the scenario that could cause losses.
USDe depegged to $0.65 in October 2025.
It traded at $0.65 on Binance for about 40 minutes. On Curve, Uniswap and Fluid it stayed within about 0.3%, and redemptions continued. Both statements are true, and people on Binance were genuinely harmed.
ENA backs USDe.
ENA is a governance token. It is not part of the reserves and USDe's backing does not depend on ENA's price.
USDe is fully backed by a futures trade.
Only partly, and less each year. In April 2026 about 13% of backing was in the crypto basis trade. Most was in liquid stablecoins and lending.
USDe complies with the GENIUS Act.
USDtb, issued by Anchorage Digital Bank, is the GENIUS-aligned product. USDe sits outside that framework and outside the EU's MiCA.
The fee switch is on, so ENA holders earn revenue.
The vote passed in September 2026. Buybacks start only when USDe supply averages above $7.5B for 14 days. In early October 2026 it was about $4.8B.
Anyone can redeem USDe for a dollar.
Only whitelisted firms that pass compliance checks can redeem with the protocol. Everyone else sells on a market at the market price.

FAQ
Short answers to the questions people ask most.
What is Ethena in simple terms?
Ethena is a crypto protocol that issues USDe, a token designed to be worth one US dollar. Instead of holding dollars in a bank, it holds a mix of assets, including crypto that is hedged with an offsetting short futures position so that price moves cancel out. People who stake USDe receive sUSDe, which earns a variable yield from the protocol's income.
Is USDe a stablecoin?
It behaves like one, but Ethena calls it a synthetic dollar because it is not backed one-for-one by cash in a bank. It falls outside the legal definitions of a payment stablecoin in the US GENIUS Act and the EU's MiCA rules. Ethena's separate token USDtb is the conventional, fiat-backed stablecoin.
Is USDe safe?
It is not risk-free. USDe is not a bank deposit and is not insured. It depends on derivatives exchanges, custodians, funding rates and market liquidity. It has kept its backing and honoured redemptions through several crises, but it traded at $0.65 on Binance for about 40 minutes in October 2025, and its supply fell by about two thirds over the following six months.
Where does the sUSDe yield come from?
From what the backing earns: funding payments on short perpetual futures, staking rewards on ETH collateral, interest on stablecoins and tokenised Treasury assets, and lending. It is variable. It briefly exceeded 60% in March 2024, was about 3.5% in April 2026 and about 4.8% in early October 2026.
What happens if funding rates go negative?
sUSDe stops earning, the reserve fund covers the shortfall, and Ethena moves backing from futures into stablecoins. Holders also tend to redeem, which shrinks the trade. If negative funding were severe and long enough to exhaust the reserve fund while the futures book was still large, USDe's backing could fall below one dollar per token. That has not happened to date.
Is USDe like Terra's UST?
Structurally, no. UST was backed by its sister token LUNA and collapsed in a self-reinforcing spiral. USDe is backed by outside assets and ENA plays no part in the backing. The similarity is behavioural: much of the demand came for yield and left when yield fell.
What is the ENA token for?
ENA is the governance token. Holders elect the Risk Committee and vote on backing assets and revenue use. A fee switch approved in September 2026 will use protocol revenue to buy back ENA once USDe supply averages more than $7.5 billion for 14 days. ENA does not back USDe.
Who founded Ethena?
Guy Young, a former Cerberus Capital Management investor, founded Ethena Labs in 2023. The design was inspired by Arthur Hayes's March 2023 essay Dust on Crust. Hayes is an investor through his family office Maelstrom.
Can I use Ethena in the United States or Europe?
Ethena's app is closed to US users, and Ethena withdrew from the EU and EEA in 2025 after action by the German regulator BaFin. USDe and ENA still trade on some exchanges that serve those regions, and Kraken began offering USDe rewards in April 2026. Availability depends on the platform and your country.
What is USDtb?
USDtb is a fiat-backed stablecoin from the Ethena ecosystem, issued by Anchorage Digital Bank under the US GENIUS Act framework and backed mainly by BlackRock's tokenised Treasury fund BUIDL. It is used inside USDe's backing, in the reserve fund and behind white-label stablecoins.
How much USDe is there?
About $4.8 billion in early October 2026. The peak was about $14.8 billion on October 10, 2025, and the 2026 low was about $3.9 billion at the end of April.
What is StablecoinX?
A Nasdaq-listed company, ticker USDE, that holds about 3 billion ENA, close to 20% of total supply. It began trading on June 26, 2026. Its shares are equity in a company and are not USDe.
Did the Converge blockchain launch?
Not as far as we could verify by October 2026. Converge was announced with Securitize in March 2025 with a mid-2025 target. A project built for it shut down in December 2025 saying the chain was indefinitely postponed.
Is this site affiliated with Ethena?
No. whatisethena.com is an independent educational resource. It is not affiliated with Ethena Labs or the Ethena Foundation, and nothing here is financial advice.
