Backup Verification

How It Works

Backup verification means periodically restoring your wallet from backup to confirm it produces the expected addresses and balances. For a single-sig wallet, this involves entering your seed phrase (and passphrase, if used) into a hardware wallet and verifying that it generates the same addresses that hold your funds. For multisig, verification is more complex — you need to confirm that each key, the wallet descriptor, and the coordination software all work together to reconstruct the wallet.

The most common failure modes are subtle. A seed phrase with one wrong word. A passphrase that was remembered slightly differently. A multisig configuration file that wasn't backed up alongside the seed phrases. A derivation path that changed between wallet software versions. Each of these errors can make recovery impossible. Verification catches them while you still have access through your primary setup.

Verification should follow a checklist. Confirm the seed phrase produces the correct extended fingerprint (XFP). Verify the derivation path matches your wallet configuration. For multisig, confirm the wallet descriptor is backed up and produces the correct addresses. Check that metal backups are legible and undamaged. Test the full recovery procedure, not just reading the words — actually restore a wallet and verify it shows your funds. Schedule verification at least annually, or whenever you change any part of your custody setup.

Key Points

• An untested backup is not a backup — verify recovery works before you depend on it
• Common failures include wrong word order, missing passphrases, and lost multisig configurations
• Verify the extended fingerprint (XFP) matches your expected keys during restoration
• For multisig, the wallet descriptor is as critical as the seed phrases — back it up and verify it
• Schedule verification at least annually and after any changes to your custody setup
