CoinFello, an AI agent that works directly with smart contracts, has unveiled its open-source OpenClaw skill in collaboration with MetaMask. This partnership allows AI agents to securely carry out onchain transactions using delegated smart wallet permissions. The announcement was shared with Finbold on March 11.
The integration of OpenClaw enables Moltbots, personal AI agents operating on the OpenClaw framework, to execute blockchain actions while users maintain control over their private keys.
The system utilizes ERC-4337 smart accounts and ERC-7710 delegations via the MetaMask Smart Accounts Kit, allowing agents like CoinFello to perform specific tasks on behalf of users.
Delegated permissions framework for AI agent transactions
CoinFello’s framework connects AI agents with crypto wallets without the need for agents to store private keys or API credentials. Permissions are granted through a delegated access model, where a user’s Moltbot can authorize another agent to complete a particular transaction without full 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 verifies 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,” stated Brett Cleary, CTO at CoinFello. “The CoinFello Skill introduces hardware-isolated keys and fine-grained delegations, providing AI agents with a secure way to execute transactions while aiding in the development of onchain capabilities for the wider agent ecosystem.”
CoinFello highlighted that their 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 mitigate this risk through server-side trusted execution environments, they still rely 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.
Through natural-language prompts, Moltbots can perform various blockchain actions using the system, such as swapping ERC-20 tokens, bridging across EVM networks, interacting with NFTs like ERC-721 and ERC-1155 tokens, staking, lending, rebalancing token portfolios, and executing multi-step trading strategies.
The OpenClaw skill from CoinFello is based on the Agent Skills specification and is compatible with OpenClaw environments and Claude Code. The implementation has been made available under the MIT license, enabling developers to deploy and customize it in their own AI agent environments.
The company also mentioned that while CoinFello serves as the default Web3 agent in the system, Moltbots can delegate permissions to any compatible onchain agent. Future developments will focus on expanding permission frameworks and further integrating with the MetaMask Smart Accounts Kit.
This release comes amidst the growth of the OpenClaw ecosystem. The project’s GitHub repository has exceeded 150,000 stars and 22,000 forks in the last two months, with npm downloads surpassing 416,000 in the previous 30 days.
