A fully self-custodial agent wallet that lets AI agents trade autonomously without forcing users to give up control. Deploying an agent on a self-custody wallet can mean choosing between giving the agent freedom to act and keeping users’ funds safe. MetaMask Agent Wallet ends that trade-off. Your agent operates inside user-defined limits.
:::info Early Access MetaMask Agent Wallet is available through the Early Access Program. :::
After setup, prompt your agent in plain language:
| You ask your agent | What happens |
|---|---|
| "Show the wallet address and USDC balance on Base" | Your agent checks auth, then queries balances. |
| "Send 10 USDT to 0x123… on Base" | Your agent confirms details, then submits a transfer. |
| "Swap 0.1 ETH to USDC on Base" | Your agent fetches a quote, confirms with you, then executes. |
| "Open a 5x long on BTC with $100 on Hyperliquid" | Your agent deposits if needed, quotes, and opens the position. |
| "Bet 10 USDT on YES for BTC 5-min price up" | Your agent searches markets, confirms odds, and places the order. |
Security by default, not configuration. Supported EVM transactions pass through a mandatory 3-step security pipeline. Backed by Transaction Protection: transactions through Agent Wallet deemed safe are guaranteed against loss up to $10,000.*
- Transaction simulation: What will this transaction actually do? Balance changes, approvals, and gas are surfaced before signing.
- Transaction Shield: Automated security checks flag malicious contracts and scams; flagged transactions require your approval before they execute.
- Smart Transactions: Smart transaction execution with built-in MEV protection, fewer fails, and better gas where supported on the target chain.
