Send Bitcoin

In order to send bitcoin, you will need to sign on 2-of-3 of your hardware wallets.

At this point, you should’ve completed all the previous sections. Once you’ve verified your receive addresses and backed up your wallet, it’s safe to receive bitcoin.

Now we’ll go over how to spend some of them.

  1. On Specter-Desktop: Your Multisig Wallet (e.g. Redundant Multisig) > Send > New. Fill out the transaction info and hit Create unsigned transaction:

  2. The transaction will now exist in an unsigned state. Click Open so you can sign it with your hardware wallets (Keystone (formerly Cobo Vault) and Coldcard):

  3. Select Keystone to sign with first (order doesn’t strictly matter):

  4. Sign via QR code (best airgap & UX):

  5. On Keystone: Menu > Multisig Wallet > scanner icon (in the top right) and scan the QR code that Specter-Desktop is displaying.

  6. On Keystone: sign the transaction.

  7. On Specter-Desktop: Scan signed transaction and hold up Keystone to your computer’s QR code scanner:

  8. Select Coldcard to sign with second (order doesn’t strictly matter):

  9. Select USB and pick which USB device to do the signing:

  10. On Coldcard: confirm transaction:

  11. Broadcast the signed transaction:
