Gate News 消息，3 月 12 日，AI 代理开发商 CoinFello 发布开源技能 OpenClaw，允许 AI 代理安全连接 MetaMask 并执行链上交易，全程无需访问用户私钥。该技能基于 MetaMask 智能账户套件构建，采用 ERC-4337 智能账户与 ERC-7710 委托机制。用户可为 AI 代理授予执行特定任务所需的最小权限，有效规避现有 AI 代理钱包普遍面临的提示注入攻击风险。CoinFello 首席技术官 Brett Cleary 表示："如果我们希望代理有意义地参与链上经济，就需要一个比直接交出私钥更好的安全模型。"支持功能涵盖 ERC-20 代币兑换、跨 EVM 链桥接、NFT 交互、质押、借贷及多步交易策略，均可通过自然语言指令触发。该技能以 MIT 许可证发布。
