Hardware wallets

BAL works with any hardware wallet supported by Electrum — Ledger, Trezor, Coldcard, BitBox02, Jade, KeepKey and others.

{ .screenshot } The plugin builds the transaction; your device signs it.

The division of labour is the same as for a normal Electrum transaction:

• the plugin builds the inheritance transaction,
• Electrum submits it for signature,
• your device signs — with your physical confirmation.

The plugin never has access to your keys and never signs on your behalf.

!!! tip "Cold signing setup" For maximum security, use a dedicated computer for signing. Note that with BAL you will need to sign more than once over time: every refresh of the will requires a new signature — see Keeping the will up to date.
