XMTP Chain is a Layer-3 appchain built with Arbitrum that settles to Base, providing a decentralized ledger to consistently order XMTP’s messaging metadata.
The XMTP API allows interaction with the XMTP 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.
