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.
“The CoinFello Skill introduces hardware-isolated keys and fine-grained delegations, giving AI agents a secure way to execute transactions while helping bootstrap onchain capabilities for the broader agent ecosystem,” Cleary stated.
The launch comes as the OpenClaw ecosystem sees rapid growth, with over 150,000 GitHub stars, 22,000 forks, and more than 416,000 npm downloads in the past month.
Moltbots can perform actions such as ERC-20 swaps, cross-chain bridging, NFT interactions, staking, lending, portfolio rebalancing, and multi-step trading strategies through natural-language prompts.
The skill follows the Agent Skills specification, works with OpenClaw environments and Claude Code, and is released under the MIT license for developer use and modification.
CoinFello says Moltbots can delegate permissions to any compatible onchain agent, with future development focusing on expanded permission frameworks and deeper MetaMask Smart Accounts Kit integration.
