MetaMask is testing a sharper version of the AI-agent idea: an agent that can hold a self-custodial wallet and act in DeFi. Agent Wallet opened in early access on June 8.
Trading access with guardrails
The wallet supports swaps, perpetuals, prediction markets and liquidity provision across Ethereum, Linea, Arbitrum, Avalanche, Optimism, Base, Polygon, BSC, Sei and Hyperliquid. It is designed to connect to agent environments such as Claude Code, OpenAI Codex, Cursor, OpenClaw and Nous Research’s Hermes.
MetaMask is framing security as the product. Every transaction passes simulation, Blockaid threat scanning and MEV protection. Guard Mode sets daily spending limits and protocol allowlists, while Beast Mode gives agents more room but still requires 2FA for suspicious activity.
The bet is that agents will eventually manage real capital, not just draft text or code. MetaMask wants to be the wallet layer that lets that happen without handing unlimited authority to software.
