CoinFello, an AI agent that interacts directly with smart contracts, has partnered with MetaMask to deploy open source OpenClaw skills to enable AI agents to securely execute on-chain transactions through delegated smart wallet privileges, according to an announcement shared with Finbold on March 11.
This integration enables Moltbot, a personal AI agent running on the OpenClaw framework, to perform blockchain actions while giving users control over their private keys.
This system uses ERC-4337 smart accounts and ERC-7710 delegation through the MetaMask smart account kit to enable agents such as CoinFello to perform narrowly defined tasks on behalf of users.
Delegated authority framework for AI agent transactions
According to CoinFello, the framework connects AI agents to cryptocurrency wallets without the need for agents to store private keys or API credentials. Instead, privileges are granted through a delegated access model. This model allows a user’s Moltbot to authorize another agent to complete a specific transaction without extensive access to the wallet.
The system follows a least privilege design. When a user submits a natural language request, CoinFello converts that instruction into a delegated transaction and validates it through an evaluation layer before execution.
“If we want agents to meaningfully participate in the on-chain economy, we need a better security model than handing over private keys to autonomous systems.” Brett Cleary, CTO of CoinFello, said: “The CoinFello skill introduces hardware-separated keys and fine-grained delegation, giving AI agents a secure way to execute transactions while helping bootstrap the on-chain functionality of the broader agent ecosystem.”
CoinFello said this approach differs from many existing AI agent wallet designs that rely on storing private keys and API credentials within the agent environment. Some new systems attempt to reduce this risk through server-side trusted execution environments, but still rely on centralized infrastructure.
With OpenClaw skills, the signing key remains on the user’s device while the agent performs the task through ERC-7710 delegation. This allows the agent to perform transactions without direct access to the private key.
Using natural language prompts, Moltbot can perform a variety of blockchain actions through the system, including exchanging ERC-20 tokens, bridging between EVM networks, interacting with NFTs such as ERC-721 and ERC-1155 tokens, staking, lending, rebalancing token portfolios, and executing multi-step trading strategies.
According to CoinFello, OpenClaw skills are built on the Agent Skill Specification and are compatible with the OpenClaw environment and Claude code. This implementation is released under the MIT license, allowing developers to implement and modify it in their own AI agent environments.
The company also noted that CoinFello acts as the default Web3 agent in the system, while Moltbot can delegate authority to compatible on-chain agents. Future development will focus on extending the permissions framework and further integration with the MetaMask Smart Account Kit.
This release comes amidst growth in the OpenClaw ecosystem. In fact, the project’s GitHub repository has surpassed 150,000 stars and 22,000 forks in the past two months, and over 416,000 npm downloads in the past 30 days.
