Cap is a stablecoin protocol that provides credible financial guarantees via two products: the dollar-denominated cUSD and the yield-bearing stcUSD. cUSD is a digital dollar issued on the Ethereum blockchain that can be used on any network. cUSD's reserve is backed by blue chip stablecoins such as USDC, USDT, pyUSD, BUIDL, and BENJI, i.e. issued by regulated institutions with transparent attestations. It is 1:1 redeemable for any of the available reserve assets.
