INTRODUCING | MetaMask Introduces AI Agent Wallet with Built-in DeFi Controls

MetaMask has rolled out a new ‘Agent Wallet’ that allows artificial intelligence systems to interact with decentralized finance (DeFi) protocols while operating under strict user-defined security limits.

The wallet, currently in early access, is designed to let AI agents execute crypto trades, liquidity provision, and other on-chain actions across multiple blockchain networks, but with guardrails intended to prevent unauthorized or risky activity.

Users can assign operating rules such as spending caps, approved protocols and transaction limits, while all actions remain subject to security checks and approval requirements when activity falls outside those parameters.

The system introduces two operating modes:

• a default ‘Guard Mode,’ which enforces tighter controls and requires human confirmation for certain transactions, and
• an optional ‘Beast Mode,’ which reduces interruptions for more advanced users while still flagging suspicious activity.

All transactions are routed through MetaMask’s security stack which includes simulation, threat detection, and protection against malicious contracts and maximal extractable value (MEV) attacks.

MetaMask said transactions deemed safe may also be covered under its Transaction Protection program offering limited financial coverage in case of loss.

The move comes as AI agents are increasingly being integrated into crypto trading systems raising questions about how to balance automation with user control and security in decentralized markets.

MetaMask’s Agent Wallet is initially available to a limited group of users with broader access expected later in 2026.
