MetaMask has launched Agent Wallet, a self-custodial wallet designed for AI agents to autonomously execute on-chain transactions. The wallet includes transaction simulation, threat detection, and mandatory security checks to reduce risks from autonomous software. Early Access Program admits about 200 users, with broader availability planned this summer. The launch addresses risks from AI agents directly accessing private keys—a practice that could reintroduce custodial mistakes. Agent Wallet routes transactions through MetaMask's security infrastructure, including Blockaid-powered threat scanning and Clear Signing. Default Guard Mode lets users define spending limits and approved protocols; transactions exceeding rules trigger 2FA. Beast Mode allows more freedom but still requires 2FA for flagged transactions. The wallet supports EVM chains, Hyperliquid, and agent frameworks like OpenAI Codex. It uses Cubist's TEE to keep private keys hardware-isolated. Other companies like Coinbase and MoonPay are also launching similar infrastructure.
