USDS risks

Collateral and liquidations

A sharp crash in the crypto collateral can outrun liquidations and leave the system under-backed.

Smart contracts and oracles

Bugs, governance attacks or bad price feeds can drain collateral or trigger wrongful liquidations.

Bridged versions

Copies of a stablecoin moved by third-party bridges depend on those bridges. Prefer the issuer's native contract on each chain.

Regulation

Rules such as the US GENIUS Act and the EU's MiCA can restrict which stablecoins exchanges list in a given country.
