@zakyirsyaad/monagent-plugin

MetaMask Agent Wallet (mm) plugin for agent-to-agent commerce on Monad: payments in MON and ERC-20, ERC-8004 identity and reputation, x402 paid API calls, and task escrow. Every write goes through the MetaMask wallet executor and its transaction protection policy; the plugin never sees keys.

Supports Monad Mainnet (143) and Monad Testnet (10143). Requires @metamask/agent-wallet 6.2+ or 7.x.

Install

npm install -g @metamask/agent-wallet@7
mm config set experimentalPlugins true
mm config set experimentalAllowUnverifiedInstalls true
mm plugins install @zakyirsyaad/monagent-plugin --accept-permissions
mm login   # needed for write commands
mm init    # first run only

Commands

Every command takes --chain-id 10143|143 (default 10143, testnet). Add --json for machine-readable output.
