MetaMask has launched early access for Agent Wallet, a new wallet setup built for AI agents operating on Ethereum. This isn’t just a new user interface; it’s a different wallet model for software that may need to act autonomously while the user still keeps control.
The core feature is that it stays non-custodial: MetaMask does not hold the keys or assets; the user does. What changes is how the wallet puts guardrails around that autonomy. Every transaction an agent wants to initiate must go through mandatory simulation before submission. MetaMask says those simulations predict the balance changes a transaction would cause before it is sent on-chain.
Agent Wallet also uses spending limits, so an AI agent can be authorised to act within a defined budget rather than getting open-ended access to funds. The point is not to hand full control to AI, but to let software handle on-chain actions inside boundaries set by the wallet owner. In MetaMask’s framing, the key issue with AI agents is not only what they can do, but what they can do safely.
