MetaMask Launches AI Agent Wallet With Built-In Security Controls
MetaMask launched Agent Wallet, a self-custodial wallet for AI agents to trade and interact with DeFi under user-set security controls. It is in early access for about 200 users, with broader release planned for later this summer. MetaMask says many agent products expose private keys directly, creating risk from mistakes or prompt-injection attacks, so Agent Wallet is built to reduce damage when agents go wrong rather than assuming models are fully safe. The wallet uses MetaMask security tools such as transaction simulation, scam and malicious-contract detection, Clear Signing, and MEV protection. In default Guard Mode, users set spending limits, approved protocols, and other rules; suspicious or out-of-policy actions require 2FA. Beast Mode is more autonomous, but malicious transactions still trigger approval. Agent Wallet supports EVM chains, Hyperliquid, and several AI frameworks, and keeps keys inside a hardware-isolated enclave via Cubist TEE technology. MetaMask’s move follows similar agent-wallet offerings from Coinbase and MoonPay.
