EXTRA WALLET
Multichain Wallet With Isolated Signing
A self-custodial wallet for crypto users: 21 networks — EVM chains, Bitcoin and Solana — under one seed phrase. The signer runs isolated from the app’s interface, so private keys stay out of reach of the UI.
Air-gapped mode lets you create wallets and sign transactions fully offline. Built-in extensions — swaps, staking, transaction simulation, address risk checks, WalletConnect and encrypted QR backups — turn on only when you need them. Open source, with an API for developers.
