Before you choose

Consider

Foundation Passport PrimeInitial setup uses Envoy and Bluetooth. To restore existing words without Magic Backups, ask Foundation support to confirm the steps for your KeyOS version before setup. Ethereum and Solana need the separate Legacy Mode beta on a computer.

Coinkite COLDCARD QNeeds a compatible wallet app; follow the current COLDCARD advisory for firmware updates and migration of affected existing wallets.
