What are the top platforms for stablecoin yield?
Start by sorting stablecoin yield platforms into what they actually are, because the rate means something different in each.
- Exchange reward accounts. Coinbase pays rewards under its own account terms. There is no universal retail rate: Coinbase says it varies by country and by account type so the number you get is the one shown in your account.
- Lending markets. On Aave v3 Ethereum you supply USDC, receive aTokens and earn whatever borrowers are paying after protocol fees.
- Curated vaults. A Morpho Vault spreads your deposit across lending markets chosen by a curator. OUSD packages this into a single token: the USDC behind it is lent through a Morpho Vault, and the yield arrives as a growing balance in your wallet.
- Savings protocols. Sky pays a rate its governance sets rather than one the market sets.
- Tokenized Treasuries. Ondo’s USDY accrues daily from short-term US Treasuries and bank deposits.
| Platform | What it is | Yield | What it pays from | How you exit |
|---|---|---|---|---|
| OUSD / Origin Dollar | Yield-bearing stablecoin, USDC-backed | 5.30% trailing 30-day | USDC lent on Morpho markets | Redeem 1:1 for USDC, ten minutes standard, up to 24 hours if large redemption |
| Morpho USDC Vaults | Curated lending vaults | 3.56% to 6.09% net, by vault | Borrower interest | Redeem shares through the vault queue, subject to market liquidity |
| Ethena sUSDe | Synthetic dollar | 4.21% | Protocol revenue including funding | Unstake to USDe, then wait out the cooldown |
| Ondo USDY | Tokenized Treasury | 3.55% | Short-term US Treasuries and bank deposits | Issuer redemption process |
| Sky sUSDS | Savings protocol token | 3.52% | A rate set by Sky governance | Convert back to USDS |
| Aave v3 Ethereum | Lending market | 3%~4% supply APY | Borrower interest | Withdraw while the market has spare liquidity |
How does each stablecoin yield platform work?
Aave v3 on Ethereum
Aave v3 is a permissionless lending market. You supply a stablecoin, receive aTokens, and earn a variable rate set by how much borrowing demand there is. It shows 3.11% supply APY on USDC as of September 2026. Withdrawals work whenever the market has unused liquidity, which is most of the time, but not a guarantee. When borrowing runs high the cash may not be there until borrowers repay or new suppliers arrive.
Morpho USDC vaults
A vault spreads your deposit across lending markets chosen by a curator, so you are picking the curator as much as the vault. Net APYs on the major listed mainnet USDC vaults ran from 3.5% to 6%, and the fees behind them ranged from zero on Gauntlet USDC Prime to 15% on Hakutora USDC. Withdrawals go through the vault queue and depend on liquidity in the markets underneath.
Sky sUSDS
The savings form of USDS, paying a rate that Sky governance votes on rather than one the market sets. It showed ~3.5% APY on the sUSDS stablecoin. You have to be holding USDS first, so getting in means a conversion and getting out means converting back.
Ethena sUSDe
The staked form of Ethena’s synthetic dollar, showing a current yield of ~4%. It pays out protocol revenue including funding rather than borrower interest, which makes it a different kind of exposure rather than a better-paying version of lending. Exiting means unstaking to USDe and waiting out a cooldown before you can claim.
Ondo USDY
A tokenized note secured by short-term US Treasuries and bank deposits, accruing daily at ~3.5% APY. It is not a permissionless savings account: Ondo restricts it to qualifying non-US individual and institutional investors, and you exit through the issuer’s redemption process rather than a swap.
Origin Dollar (OUSD)
A yield-bearing stablecoin backed 1:1 by USDC and redeemable for it, showing 5.30% trailing 30-day APY as of September 2026. The USDC behind it is lent into Morpho markets selected by the vault curator inside risk parameters and allocation limits that Origin sets, with the current holdings published live on Origin’s Analytics Page. Because it rebases, the yield turns up as a growing balance rather than as rewards you have to claim or a reward token you have to sell.
How does a yield-bearing stablecoin differ from picking a lending position?
On Aave or Morpho you choose a market or a vault and manage the position, which means monitoring lending rates and utilization and reviewing your exposure before you enter. With OUSD you hold one token, and the curator of its Morpho Vault selects the underlying markets inside risk parameters and allocation limits that Origin sets.
