Citrea

Citrea is a zero-knowledge (ZK) rollup platform that enables the creation of Bitcoin-native applications (Bapps) secured by the Bitcoin network. The platform provides a BitVM-based bridge for trust-minimized Bitcoin (cBTC) and a fiat-backed stablecoin (ctUSD) to facilitate Bitcoin capital markets. It targets institutional and retail users by offering financial primitives such as lending, yield products, and decentralized exchanges on a programmable layer.
