CoinFello, an AI agent built for secure smart contract interaction, has unveiled an open-source OpenClaw skill in partnership with MetaMask to enable Moltbot’s AI agents to execute on-chain transactions using delegated smart wallet permissions.
Built on ERC-4337 smart accounts and ERC-7710 delegations via the MetaMask Smart Accounts Kit, the framework allows users to maintain custody of private keys while granting limited permissions to agents like CoinFello.
The system follows a least-privilege model. CoinFello converts natural-language user requests into delegated transactions that are validated before execution, reducing the need to expose private keys or API credentials, CoinFello stated.
The release reflects growing momentum around AI agents interacting with blockchain infrastructure.
According to CoinFello CTO Brett Cleary, the industry needs more robust security approaches if AI agents are to play a meaningful role in the onchain economy, rather than relying on models that provide autonomous systems with private keys.
