Hardware wallets

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

Confirming on the hardware wallet 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.

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.
