Bitcoin Layer 2 project Citrea, backed by Founders Fund and Galaxy, has officially launched its mainnet and introduced its native stablecoin ctUSD. Citrea uses zkEVM to batch process transactions off-chain, generate zero-knowledge proofs, and inscribe them onto the Bitcoin mainnet, enabling native Bitcoin settlement and data availability. Citrea will focus on BTC collateralized lending and structured products. ctUSD is issued by MoonPay, built on the M0 stablecoin infrastructure, fully backed by short-term U.S. Treasury bonds and cash, and complies with GENIUS Act requirements.
