CoinFello, an AI agent built for secure smart contract collaboration, partnered with MetaMask to discover an open-source OpenClaw skill to enable Moltbot’s AI agents to execute on-chain transactions using authorized smart wallet permissions.
Built on ERC-4337 smart accounts and ERC-7710 delegations via the MetaMask smart account suite, the framework allows users to maintain private key storage while granting limited permissions to agents like CoinFello.
The system follows the model of least privilege. CoinFello turns natural user requests into authorized transactions that are validated before execution, reducing the need to expose private keys or API credentials, CoinFello said.
The release reflects the growing pace of AI agents interacting with blockchain infrastructure.
According to CoinFello CTO Brett Cleary, the industry needs robust security approaches if AI agents are to play an effective role in the onchain economy, rather than relying on models that provide autonomous systems with private keys.
“CoinFello Skill introduces hardware-decoupled keys and precision delegation, offering AI agents a secure way to execute transactions while helping to leverage onchain capabilities for the broader agent ecosystem,” Cleary said.
The launch comes as the OpenClaw ecosystem has seen rapid growth, with more than 150,000 GitHub stars, 22,000 forks, and more than 416,000 npm downloads in the past month.
Moltbots can perform operations such as ERC-20 swaps, cross-chain money, NFT collaboration, staking, lending, portfolio balancing, and multi-step trading strategies through natural language queries.
The skill follows the Agent Skills specification, works with the OpenClaw and Claude Code environments, and is released under the MIT license for developer use and modification.
CoinFello says Moltbots can delegate permissions to any suitable onchain agent, and future development will focus on broader permission frameworks and deeper MetaMask Accounts Kit integration.
