Utilizing zkEVM technology, Citrea processes transactions off-chain, generating zero-knowledge proofs that are then recorded on the Bitcoin mainnet, ensuring native settlement and data availability. The platform aims to support BTC-collateralized lending and structured products. The ctUSD stablecoin is issued by MoonPay and is based on the M0 stablecoin infrastructure. It is fully backed by short-term U.S. Treasury bills and cash, complying with the GENIUS Act requirements.
