Below is my wsh descriptor compiled from two Coldcards Mk4. This will allow you to actually send and receive bitcoins to and from this bitcoin address. If the address does NOT match, alter the order of the public keys and try again. Double check that the address generated matches the 3-of-3 MultiSig address. Also you can scan QR code keys from paper wallet. Replicate the 3-of-3 MultiSig using the 'New -> MultiSig Address' feature of Coinb.in: Enter the 3 public keys for the 3 private keys into the boxes provided. You can enter WIF (Wallet Import/Export Format) or compressed private key. ![]() Then click Import Existing Bitcoin Address.
