When you deposit assets, they go into a smart contract from Angle Protocol, called the stUSD contract for Dollar savings or the stEUR contract for Euro savings. You can either deposit USDA or EURA which are directly added to the stUSD or stEUR contracts, or deposit other assets (like USDC or EURC), which are automatically swapped into USDA or EURA before being deposited in the contract. There are no minimum deposits, no protocol fees, no lockup period, and you can withdraw your funds at any time!

stUSD (staked USDA) and stEUR (staked EURA) are yield-bearing USD and EUR stablecoins. You receive stUSD or stEUR when depositing assets (USDA, USDC, EURC…) into the Angle savings product. stUSD and stEUR’s value continuously increases over time by accruing yield. Thus, 1 stUSD is worth more than $1 today, and 1 stEUR is worth more than 1€. stUSD and stEUR are ERC20 tokens available on multiple networks — you can freely swap them for any other token, anytime, anywhere.

stUSD and stEUR holders start earn a passive & native yield within seconds of acquiring stUSD or stEUR (whether by directly swapping assets or depositing stablecoins into the Angle savings product). Yield stems from returns generated by assets backing USDA and EURA (such as real-world assets and DeFi yield-bearing assets) as well as interest paid by USDA and EURA borrowers.

You will start earning yield immediately after acquiring stUSD or stEUR. Yield is distributed with every block (≈ 12 sec. on Ethereum). You’ll keep earning as long as you hold your stUSD or stEUR tokens. You can swap your stUSD or stEUR — whose value increases over time — at any time, but you will stop earning yield once you do.

As with any DeFi product, zero risk doesn't exist. Although the stUSD and stEUR smart contracts are undergoing regular audits, there are risks associated with interacting with them, as well as counterparty risk or blockchain risk. Learn more about the risks in the documentation.
