CoinFello, an AI agent that interacts directly with smart contracts, has introduced its open-source OpenClaw skill in partnership with MetaMask, allowing AI agents to securely execute onchain transactions through delegated smart wallet permissions, according to an announcement shared with Finbold on March 11.
The integration enables Moltbots, personal AI agents running on the OpenClaw framework, to carry out blockchain actions while users retain control of their private keys.
The system uses ERC-4337 smart accounts and ERC-7710 delegations through the MetaMask Smart Accounts Kit to allow agents such as CoinFello to perform narrowly defined tasks on behalf of users.
Delegated permissions framework for AI agent transactions
According to CoinFello, the framework connects AI agents with crypto wallets without requiring agents to store private keys or API credentials. Instead, permissions are granted through a delegated access model in which a user’s Moltbot can authorize another agent to complete a specific transaction without broader access to the wallet.
The system follows a least-privilege design. When a user submits a natural-language request, CoinFello converts the instruction into a delegated transaction and validates it through an evaluation layer before execution.
“If we want agents to participate meaningfully in the onchain economy, we need a security model that is better than handing an autonomous system a private key,” said Brett Cleary, CTO at CoinFello. “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.”
CoinFello said the approach differs from many existing AI agent wallet designs that rely on storing private keys or API credentials within the agent environment. While some newer systems attempt to reduce this risk through server-side trusted execution environments, they still depend on centralized infrastructure.
With the OpenClaw skill, the signing key remains on the user’s device, while agents carry out tasks through ERC-7710 delegations. This allows agents to execute transactions without direct access to the private key.
Using natural-language prompts, Moltbots can perform various blockchain actions through the system, including swapping ERC-20 tokens, bridging across EVM networks, interacting with NFTs such as ERC-721 and ERC-1155 tokens, staking, lending, rebalancing token portfolios, and executing multi-step trading strategies.
CoinFello said the OpenClaw skill is built on the Agent Skills specification and is compatible with OpenClaw environments and Claude Code. The implementation has been released under the MIT license, allowing developers to deploy and modify it in their own AI agent environments.
The company also noted that while CoinFello acts as the default Web3 agent in the system, Moltbots can delegate permissions to any compatible onchain agent. Future development will focus on expanding permission frameworks and further integration with the MetaMask Smart Accounts Kit.
The release arrives amid growth in the OpenClaw ecosystem. In fact, the project’s GitHub repository surpassed 150,000 stars and 22,000 forks in the past two months, and npm downloads exceeded 416,000 in the previous 30 days.
