The stablecoin and governance ecosystem developed from MakerDAO, including USDS, its sUSDS savings-vault representation, and the SKY governance token.

An Ethereum validity rollup with Cairo-based execution and native smart-contract accounts; proofs establish valid state transitions while transaction receipts separately report execution and settlement status.
