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.
Check out our XMTP API Quickstart guide to get started building on XMTP.
The XMTP API lets you interface with the XMTP mainnet. You can execute transactions, query onchain data, and interact with the XMTP network using the JSON-RPC standard.
Yes, XMTP is EVM compatible.
XMTP uses the JSON-RPC API standard. This API enables blockchain interactions on the XMTP network, letting you read block/transaction data, query chain information, execute smart contracts, and store data onchain.
XMTP supports standard Ethereum JSON-RPC methods. Some chain-specific methods may vary. Please check the XMTP API Endpoints for a complete list.
When accessing the XMTP network via a node provider like Alchemy, you use an API key to send transactions and retrieve data from the network. For the best development experience, we recommend that you sign up for a free API key.
Common Ethereum libraries like ethers.js should be compatible with XMTP, given its EVM nature.
