# USDr & sUSDr

### USDr

USDr is the USD stablecoin of Rocky. It is a decentralized, overcollateralized asset backed by a basket of cryptocurrencies and stablecoins, including yield-bearing versions such as Morpho vaults. The issuance and redemption of USDr are currently managed by Rocky modules. USDr is deployed on Sei.

## Staked USDr (sUSDr)

sUSDr is the yield-bearing version of USDr. When a user deposits USDr into the Savings Module (an ERC-4626 vault), they receive sUSDr in return. This token represents their claim on the deposited USDr plus the yield generated by the protocol. sUSDr is deployed on Sei.
