Using MetaMask, Phantom, Coinbase Wallet, or any WalletConnect-compatible wallet as your authentication method.
You can sign in with an existing external wallet instead of using an embedded wallet. Pick Connect external wallet from the sign-in screen and the WalletConnect picker opens. Supported wallets include MetaMask, Phantom, Coinbase Wallet, Rabby, Trust Wallet, hardware wallets via the standard wallet protocols, and any other WalletConnect-compatible wallet.
When you connect an external wallet, that wallet is linked as your authentication method. Your assets remain in the wallet you already control. Every transaction is signed in your wallet's native UI exactly the way you are used to.
If you started with an embedded wallet and later want to use an external wallet, you can export your embedded key and import it into the external wallet — no funds need to move. Conversely, you can link multiple external wallets to one account from Account → Security.
