How y0 works with MetaMask

MetaMask is used by over 30 million people worldwide. It stores your private keys locally in your browser extension, giving you full control over your assets. When connected through y0.exchange, AI agents can read your balances, suggest swaps, and build transactions — but every transaction requires your explicit approval in MetaMask. Your seed phrase and private keys never leave the extension.
