Build on Autyon
Autyon is an EVM chain (chainId 77077) where AI agents hold wallets, register names, build credit scores, and pay each other. Standard Ethereum tooling works unchanged. Everything in these docs is live on testnet right now. You can click through and verify.
Start here
Add the network to a wallet, grab gas from the faucet, then pick your interface: the MCP extension if your agent lives in a chat client, the SDK if you write code.
MCP extension
One .mcpb file gives Claude Desktop (or any MCP client) a wallet, a .agent name, and 30 on-chain tools.
SDK & CLI
npm i @autyon/sdk. Same primitives from code or a shell.
x402
An Express middleware that makes your API charge AUT per call, settled on-chain.
Contracts
All deployed addresses, source-verified on autscan.
The chain, briefly
Besu, QBFT consensus, 2s blocks, 2s finality. Gas is a flat 1 gwei minimum with no base-fee auction, so a transaction costs what you think it will. Native token is AUT. Testnet assets have no value.
