USDe is a dollar-tracking token issued by Ethena that is not backed by dollars in a bank. It is backed by a portfolio of crypto, stablecoins and loans, with the volatile part hedged by short futures so the whole holds a steady dollar value. sUSDe is what you get when you stake USDe, a vault token that grows in value against USDe as the protocol pays rewards into it. On 25 October 2026 that yield was about 5.1% a year, according to DefiLlama, far below the double-digit rates that made sUSDe famous in 2024. USDe itself traded at $0.9996 with about $4.6 billion in circulation, per CoinGecko.
Many explainers stop at the textbook version, ETH and bitcoin held against short futures, with the fees those futures pay as the yield. Ethena's own docs say backing was concentrated in that trade for most of the protocol's history. Today that trade is a minority of the backing. On Ethena's transparency dashboard, hedged crypto made up 15% of USDe's backing on 25 October 2026, behind DeFi lending at 35% and plain stablecoins at 27%. Supply has shrunk by more than two thirds since its October 2025 peak, and the protocol has come through two stress events since then.
What USDe is and what it is not
USDe is a synthetic dollar. A fiat-backed stablecoin such as USDT or USDC holds mostly cash and short-term government debt and promises redemption at $1 to its verified customers. USDe's value comes instead from a portfolio built to hold steady, which Ethena's backing overview describes as volatile assets paired with short derivatives positions, alongside stable assets that need no hedge. Our PYUSD explainer covers how the fiat-backed kind works, and our ranking of the safest stablecoins explains why USDe should not be judged on the same scale.
The difference that matters most to a retail holder is redemption. A verified USDC customer can hand coins back to the issuer for dollars, but a retail holder cannot hand USDe back to Ethena. Only whitelisted counterparties can, and everyone else trades it on the market.
USDe on its own also earns nothing, since Ethena's staking documentation says you have to stake it to receive rewards. ENA, Ethena's governance token, is a separate asset with a freely moving price. And sUSDe is a different animal from a tokenised Treasury fund such as Ondo's USDY, whose income comes from government debt rather than a trading and lending portfolio.
How minting and redemption work
Only approved, whitelisted counterparties deal with Ethena directly. Under the USDe terms, a "Mint User" has passed KYC and anti-money laundering checks and been whitelisted with Ethena BVI Limited, and only Mint Users can redeem USDe with Ethena. Ethena's FAQ adds that US users cannot access the application. A Mint User sends stablecoins such as USDT or USDC and receives new USDe in the same transaction, and redemption runs in reverse, only on Ethereum. On 25 October 2026 the dashboard showed about $800 million of stablecoins ready for immediate redemptions, roughly a sixth of supply, and its Fees tab listed no mint or redeem fee for USDC and 0.11% for USDT, plus gas.
That split is what holds the peg. If USDe trades at $0.97 somewhere, a Mint User can buy it there and redeem it for $1 of stablecoins, and if it trades above $1 they can mint and sell. Ethena sets out that loop on its peg arbitrage page. It only works where those arbitrageurs can reach a given venue, and that limit is what broke down on one exchange in the October 2025 crash, covered below.
The hedge inside the backing
The original design is a delta-neutral position, meaning price moves cancel out. Ethena holds ETH or bitcoin and opens a short of the same size in the perpetual future, a futures contract with no expiry that tracks the coin's price. A short gains when the price falls, so if ETH drops 20%, the loss on the coin is roughly matched by the gain on the short. What is left is the funding rate, the fee traders with leveraged long positions pay the short side, plus staking rewards if the ETH held is a liquid staking token, though the dashboard showed almost no staked ETH left in the backing by October 2026. Our guide to funding rate arbitrage covers the trade in depth.
What sets Ethena's version apart is where the collateral behind those hedges sits. Ethena keeps it with custody providers named in its custody documentation as Copper, Ceffu, Kraken and Anchorage Digital, under off-exchange settlement. The custodian keeps the coins and vouches for them to the exchange, which lets Ethena trade against them without the exchange ever receiving them, and profit and loss is settled between the two generally daily. If an exchange failed the way FTX did, the collateral would stay outside its bankruptcy estate and Ethena would lose only the profit accrued since the last settlement. That shrinks exchange risk without removing it, since Ethena still relies on the custodians and on exchange margin rules that can change in a crash. On 25 October 2026 the dashboard attributed about $820 million of hedged positions to derivatives exchanges, around $507 million of it to Binance.
What backs USDe today
On 25 October 2026, half of USDe's backing was loans, DeFi lending at 35% and institutional lending at 15%, and hedged crypto was 15%. Over 2025 and 2026 Ethena shrank the hedged position (traders call it the basis trade) and moved into lending and stable assets, aiming, as its protocol revenue page puts it, at income streams that respond to different drivers.
| Category | Value | Share of backing | Yield on that slice (per Ethena) |
|---|---|---|---|
| DeFi lending (Aave, Morpho) | $1.61B | 35% | 4.7% |
| Liquid stables (USDT, USDC, USDtb, PYUSD) | $1.25B | 27% | 4.0% |
| Institutional lending | $0.70B | 15% | 5% to 7% |
| Hedged crypto (BTC, ETH, SOL, XRP, BNB) | $0.69B | 15% | 6.1% |
| Tokenised funds (RWA) | $0.28B | 6% | 5.0% |
| Hedged shares and gold | $0.05B | 1% | 7.6% |
DeFi lending means supplying stable assets to Aave and Morpho, in overcollateralised markets where borrowers post more collateral than they borrow. Institutional lending, per Ethena's lending documentation, is overcollateralised loans to institutions that post BTC or ETH. Liquid stables include USDtb, which its docs say is issued by Anchorage Digital Bank as of October 2025, so part of the stable buffer is another token from the Ethena family. A year earlier the hedge was far bigger, as Ethena's historical data puts BTC, ETH and staked ETH at a little over a third of backing in early October 2025.
That shift moves the risk rather than removing it. USDe is now less exposed to funding turning negative and more exposed to lending and credit, meaning the health of the markets it supplies, the institutional borrowers and the stablecoin issuers whose tokens it holds. A drop across every income stream at once is less likely than under the old model, but not impossible.
The backing came to $4.59 billion against about 4.58 billion USDe, roughly one dollar per token. On top sits the reserve fund, a separate pot Ethena keeps to cover periods when the protocol loses money, and counting it the dashboard put the backing ratio at 101.4%. Ethena also publishes weekly proof of reserves reports, and the one dated 23 October 2026 was confirmed by three outside parties, HT Digital, LlamaRisk and Chainlink.
How sUSDe earns yield
Staking USDe means depositing it into Ethena's staking vault and receiving sUSDe, which rises in value against USDe as rewards arrive. On 25 October 2026 one sUSDe converted to about 1.255 USDe, read from the sUSDe contract, against one to one at launch. There is no minimum staking period, though leaving takes a cooldown, covered below.
The rewards are discretionary, and Ethena uses that word on purpose. Its rewards mechanism page says the Ethena Foundation, through a subsidiary, sets each week's rewards after the fact and pays them the following week, and the contract drips them into the vault in eight-hour instalments. When revenue is negative, nothing is paid and the reserve fund bears the cost, so sUSDe's value in USDe can stay flat but is not supposed to fall. That floor applies to the sUSDe to USDe rate only. If USDe itself traded below $1, sUSDe would fall with it.
Today's 5.1% sits near the bottom of sUSDe's history. Monthly averages on the DefiLlama series ran from about 38% in March 2024 down to between 3.5% and 5% for every month of 2026. About $1.18 billion of sUSDe was outstanding on CoinGecko, roughly a quarter of all USDe. The rate is also a share of protocol income rather than all of it, since Ethena's reserve fund page says revenue currently goes to rewards and incentives, sUSDe rewards among them, and none to the reserve fund. That fund held about $62.07 million on 25 October 2026, roughly 1.4% of supply, barely changed from about $61.9 million in October 2025. A loss larger than the fund, from a custodian failure or bad debt in a lending market, would fall on the backing and then on USDe's value.
The unstaking cooldown
Leaving sUSDe through Ethena takes two steps. You request to unstake, your USDe moves to a holding contract, and you claim it once the cooldown passes. For most of sUSDe's life that was a fixed seven days, and many guides still quote it. In March 2026 Ethena switched to a dynamic cooldown, which its governance proposal set at one, three, five or seven days depending on how well liquid backing covers expected redemptions. Ethena's governance update says it was cut to one day at activation, and the contract returned one day on 25 October 2026. The admin can raise it to 90 days, per Ethena's staking functions page, so treat today's figure as a parameter rather than a promise.
The other way out is selling sUSDe on a market, immediately but at that day's price, and Ethena's docs say it does not plan to support such markets.
Two stress tests and a shrinking supply
The first test came on 10 October 2025, when more than $19 billion of leveraged positions were liquidated in about a day, as CoinDesk reported. Galaxy Research reports that USDe traded as low as about $0.65 on Binance while it held near par on most other venues and redemption kept working at Ethena, and that Binance had not finished switching its collateral pricing to redemption-based references and later paid about $300 million in compensation. DefiLlama's USDe supply series shows circulation falling from about $14.66 billion to $12.70 billion between 10 and 12 October as holders redeemed. For anyone liquidated on USDe collateral at that exchange's price, the backing was no help, while a holder who simply kept USDe in a wallet was never forced to sell at it.
The second test, in April 2026, was larger relative to supply. On 18 April attackers took about $292 million of rsETH, a restaked-ETH token, from KelpDAO's bridge, according to Chainalysis, putting lending markets that accepted rsETH as collateral at risk. Ethena was not the target, but leveraged loops built on USDe and sUSDe in those markets, where holders borrow against their tokens to buy more, unwound fast. Ethena's governance update says Ethena-related deposits across Aave fell from $2.63 billion at the end of March to $541.5 million at the end of April, and USDe supply fell by about $1.93 billion between 16 and 30 April, roughly a third, part of a slide from $5.92 billion to $3.90 billion over March and April. It reports no peg break and no draw on the reserve fund, and Blockworks Advisory, which sits on Ethena's Risk Committee, found the cooldown stayed at one day throughout. Redemptions absorbed a bigger run than October 2025, and the episode showed how much of USDe's demand rests on leverage in the same lending markets that now hold a third of its backing.
Around those events, supply kept draining, from a peak of about $14.82 billion on 4 October 2025 to $4.59 billion on 25 October 2026, a fall of roughly 69% as yields compressed.
The risks in one place
The risks so far come down to three. The yield can fall to zero with a small buffer behind it, the backing depends on a long list of custodians, exchanges, lending markets, borrowers and issuers, and retail holders exit through markets rather than the issuer.
Central controls exist too. The staking contract has a role that can freeze sUSDe held by sanctioned or high-risk addresses, which Ethena calls a legal requirement and compares to what Circle can do with USDC, and Ethena can reject mint orders.
Regulatory risk has already played out once. Germany's regulator BaFin took action against Ethena GmbH, the German company that had been issuing USDe, and in April 2025 ordered it to wind up the business, stating that "trading in USDe tokens on the secondary market is no longer permissible in the European Union". It later ran a redemption process for holders, and Ethena's staking docs say sUSDe is not offered to EU or EEA residents.
So is the yield worth the risk? At about 5.1%, sUSDe paid roughly a point more than the three-month Treasury bill, which yielded about 4.1% on 23 October 2026 according to the US Treasury, for more counterparties and an exit through markets rather than the issuer. It suits someone who wants a dollar yield token in their own wallet and accepts that structure, and the case is thinner than when it paid double digits.
sUSDe or a managed strategy
You cannot hold USDe or sUSDe through EarnPark, but two of our managed strategies on USDT and USDC earn from related trades. sUSDe and both strategies hand the work to an operator, so the differences are what you hold, who absorbs a loss and how you get out.
Maker Core is an EarnPark strategy on USDT and USDC that runs the trade Ethena started with. Per its full description in our help centre, the usual position is ETH or SOL bought with borrowed stablecoins and staked, held against a short perpetual future of the same size, and the strategy also makes markets by placing buy and sell orders on the exchange. It runs on a major exchange with a collateral pool shared by all participants, and it uses leverage. Ethena earns about 6% on its version and has shrunk it, and Maker Core targets more partly through that leverage.
USDT DeFi and USDC DeFi are the instant option. Their help centre description calls them a delta-neutral cross-exchange interest-rate arbitrage, matched long and short positions across selected exchanges, protocols and trading venues that earn the difference in rates between them. EarnPark tags each strategy with a risk label describing the kind of risk it takes, Market-Neutral for Maker Core and Cross-Venue for DeFi, and a label describes intended exposure, not a promise against loss. Here is how the three compare as of October 2026.
| sUSDe | Maker Core (USDT, USDC) | DeFi (USDT, USDC) | |
|---|---|---|---|
| What you hold | A token in your wallet, redeemable with Ethena only by Mint Users | A claim on the company under the strategy terms | A position under the company's user agreement |
| Yield | About 5.1% realised, floating | 10% target, net of the company's margin | 10% published rate |
| A bad period | Rewards stop, the $62 million reserve fund absorbs losses, then the backing | Returns can turn negative, so you can get back less than you put in | You can lose part or all of what you allocate |
| Where it runs | Custodians, exchanges and lending markets, Binance the largest venue (about $507 million of $820 million) | A pooled exchange account, using leverage | Several exchanges, protocols and venues |
| Peg exposure | Tracks USDe, which can trade below $1 on a thin venue | A stablecoin can lose its peg while the amount owed does not change | Results in USDT or USDC, whose value can move |
| Getting out | One-day cooldown, or sell on a market | Withdrawals arrive 30 days after the request, yield accruing meanwhile | Instant, fee 0.30% plus $3.20 |
| Reserve reporting | Weekly, confirmed by outside parties | Monthly proof of reserves, self-attested | Monthly proof of reserves, self-attested |
The 5.1% is what sUSDe actually paid and the 10% figures are what our strategies target or publish, none of them guaranteed, so the gap is not like for like. The higher number comes partly from leverage, and like any strategy it carries no deposit insurance. Our monthly reserves report is published by the EarnPark group itself rather than independently audited. One more thing not to blur. Our USDT page shows up to 15% as of October 2026, and that top figure comes from Alpha Vault, a Market-Exposed strategy whose withdrawals settle monthly, not from Maker Core or DeFi. USDC, at up to 10% on our USDC page, has no Alpha Vault.
Our risk statement covers the platform-level risks, and every published rate is the base you get holding zero PARK, the platform's own token, as our page on token gating explains.
USDe is now a diversified dollar portfolio with a hedge inside it, not the funding-rate machine it launched as. Judging it means reading the backing table every few months rather than repeating the 2024 description, and that habit applies to any yield product, ours included.

FAQ
What is USDe backed by?
USDe, Ethena's synthetic dollar, was backed on 25 October 2026 by about 35% DeFi lending, 27% liquid stablecoins, 15% institutional lending, 15% hedged crypto, 6% tokenised funds and 1% hedged shares and gold, according to Ethena's transparency dashboard. A reserve fund of about $62 million sits on top as a buffer against loss-making periods.
Is USDe safe, or is it risky?
USDe is not risk free, and its risks differ from a fiat-backed stablecoin's. It is not backed by cash, it depends on custodians, exchanges, lending markets and stablecoin issuers, and its reserve fund is about 1.4% of supply. Only whitelisted counterparties can redeem it with Ethena, so on a thin market its price can briefly fall far below the backing, which matters if you sell there or have USDe posted as collateral.
What is the difference between USDe and sUSDe?
USDe is the synthetic dollar itself and earns nothing, while sUSDe is staked USDe and accrues Ethena's rewards. sUSDe is a vault token whose value in USDe rises as rewards are paid in, and one sUSDe converted to about 1.255 USDe on 25 October 2026. Unstaking goes through a cooldown, one day as of that date.
How long does it take to unstake sUSDe?
Unstaking sUSDe took one day as of 25 October 2026, under the dynamic cooldown Ethena introduced in March 2026. Under the framework its governance proposal set out, the cooldown can rise to as much as seven days when liquid backing is thin, and the contract allows up to 90 days. You can also sell sUSDe on a market straight away, at the market price.
Can USDe lose its peg?
USDe can lose its peg on individual venues, and it did on 10 October 2025, when it fell to about $0.65 on Binance while redemption kept working at Ethena. Arbitrage by whitelisted counterparties that mint and redeem directly with Ethena pulls the price back toward $1, but only where they can reach the market.
What makes USDe different from USDT?
USDT is backed mainly by cash-like reserves such as US Treasury bills held by its issuer, Tether, and verified customers can redeem it for dollars. USDe is backed by lending positions, stablecoins, tokenised funds and hedged crypto managed by Ethena, and only whitelisted counterparties can redeem it with Ethena.
