Citrea is a Bitcoin L2 zk-rollup with a Type-2 zkEVM that keeps data availability and settlement on Bitcoin—via its BitVM-based “Clementine” two-way peg—bringing full EVM compatibility to BTC.
The Citrea API allows interaction with the Citrea network through a set of JSON-RPC methods. Its design is familiar to developers who have worked with Ethereum’s JSON-RPC APIs, making it intuitive and straightforward to use.
