Jade Plus can scan QR codes of Bitcoin addresses with its camera to verify whether or not the address belongs to the wallet stored on Jade Plus. This is best practice before sharing a receiving address with a sender.
Jade Plus can verify addresses for singlesig and multisig wallets (if one is registered), as well as an address on any path when using USB or Bluetooth. However, when using the camera, Jade Plus will check addresses for any account index or change address on the paths below:
- Singlesig: m/84'/0'/0' and m/49'/0'/0'
- Multisig: m/48'/0'/0'/2' and m/48'/0'/0'/1'
Note: An address that cannot be verified does not necessarily point towards malicious behavior. A failed validation may happen if checking an address on an unsupported path, or if your address belongs to an unusually high index. If your wallet platform displays your address index, make sure Jade has a chance to check it before exiting.
Verifying a Receive Address
1.
Start your Jade Plus session using a QR communication option, then select Scan QR. Point the Jade Plus camera at the QR code of a Bitcoin address that you would like to verify.
2.
Make sure the address on Jade Plus matches the one in your companion app and is the address you want to verify. Jade Plus will then begin checking each address of your wallet to see if it finds a match. If you know the address belongs to an index greater than 499, you may select the Skip button. This will automatically jump to the next interval of 500 addresses. If you need to check a change address or adjust the account index, you can find additional settings under Edit Root.
