Hardware wallet: Emergency checklist

Preserve access. Assess the situation. Check the recovery route.

As of 6 October 2026

  1. Establish whether you can still open the affected wallet and sign transactions.
  2. Assess device loss, backup loss and possible disclosure separately.
  3. Never enter recovery words, PINs, passphrases or private keys on websites, in chats or in support messages.
  4. Check the required recovery method before a reset; preserve your only working device.
  5. Identify the backup format, required number of shares and any additional passphrase offline.
  6. Check the replacement device's supported assets, networks and accounts in the official documentation.
  7. If the backup has been exposed, prepare a new wallet with new key material.
  8. Verify the destination address on the intended trusted device; account for a test transfer and fees.
  9. After securing access, use the manufacturer's backup check and store backups separately.
