FAQ
stUSD is a staked version of USDA earning a native USD yield paid in USDA. It is a yield-bearing ERC-20 token that can be freely transferred and that is always redeemable for an ever-growing amount of USDA. The value of 1 stUSD is not meant to be $1: it increases over time as yield continuously accrues to it.
The yield is generated by the assets the Angle Protocol holds across its different minting modules. In particular, the Angle Protocol collects yield from the interest rates paid by USDA borrowers in the context of the loans that can be taken through its Borrowing module, and from specific yield-bearing assets in reserve by the protocol.
Aside from the smart contract risk, trust assumptions are the same for stUSD and USDA. Returns may vary without notice but the deposited USDA cannot be lent or used in any way. For the risk associated with holding USDA, please refer to the documentation.
There are no protocol fees to deposit or withdraw from the stUSD contract. Withdrawals can be performed at any time.
When you deposit through this page, either you provide USDA and these are directly deposited in the stUSD contract in exchange for stUSD tokens or your tokens are swapped into USDA before being deposited in the contract. You can deposit as much as you want and withdraw at any moment. There are no lock-ups and no protocol fees for using stUSD.
Your USDA is deposited into a dedicated contract within the Angle Protocol commonly referred to as the stUSD contract.
You will start earning immediately after depositing your first USDA. You can then stay in the contract and keep earning for as long as you wish (from one block to years). Even in cases where Angle changes the savings rate schedule, your USDA will remain there until you withdraw it.
You do not need to manage this position, you will earn more USDA at the rate shown continuously until the rate is adjusted by Angle Protocol following the schedule voted by governance. You do not need to do anything if the USDA Savings Rate changes. You can leave your USDA in the contract and keep your stUSD for as long as you see fit.
When users own crypto like stUSD, they have two keys: a public key for receiving funds and a private key for signing transactions. If the private key is shared or compromised, they risk losing access to their funds.
Users can manage their stUSD with online or offline wallets. Online wallets, or hot wallets, store the private key on internet-connected devices like smartphones, vulnerable to attacks. In contrast, offline wallets, also known as hardware wallets, keep the private key offline in a secure environment.
Angle Protocol recommends using the Ledger crypto wallet, the industry-leading hardware wallet, to secure stUSD. Ledger ensures robust security with private keys stored on a military-grade security chip and requires a PIN code for access. With complete isolation between private keys — kept on the hardware wallet — and users' computer or mobile device when interacting with crypto service & DApp, the ERC20 wallet Ledger keeps keys safe, granting full control over stUSD.
