ChainCatcher report: AI agent developer CoinFello has released OpenClaw, an open-source skill that enables AI agents to securely connect to MetaMask and execute on-chain transactions without requiring access to user private keys. Built on MetaMask’s Smart Account Suite, OpenClaw leverages ERC-4337 smart accounts and ERC-7710 delegation mechanisms. Users can grant AI agents only the minimal permissions necessary to perform specific tasks, effectively mitigating the prompt injection attack risks commonly associated with existing AI agent wallets. Brett Cleary, Chief Technology Officer at CoinFello, said, “If we want agents to meaningfully participate in the on-chain economy, we need a better security model than simply handing over private keys.” Supported functionalities include ERC-20 token swaps, cross-EVM chain bridging, NFT interactions, staking, lending, and multi-step trading strategies—all triggerable via natural language commands. The skill is released under the MIT License.
