What does device registration mean?

Device registration allows your key to confirm the legitimacy of addresses displayed by Unchained.

After creating an Unchained vault, you must register the details of your multisig wallet with specific hardware wallets (currently Ledger and Coldcard). Registering allows you to verify multisig addresses on the hardware wallet itself. 

The two devices we support that currently utilize this functionality are Ledger and Coldcard.Trezors can verify addresses without being registered.
