use an air-gapped method to interact with your seed phrase whilst using Sparrow.
Discussion
Thanks a lot mate
It's good to see how it works under the hood.
The rough steps once you have a 12-/24-word seed phrase involve juggling the non-sensitive data from an air-gapped device (SeedSigner) to your internet connected device (Sparrow on a laptop) using QR codes:
1. Load your seed phrase into SeedSigner
2. Scan you master public (xpub) key from SeedSigner into Sparrow
3. Create a partially signed transaction with Sparrow.
4. Load this partially signed transaction into SeedSigner.
5. Fully sign the transaction with SeedSigner.
6. Load the fully signed transaction into Sparrow.
7. Broadcast the fully signed transaction with Sparrow.
and voila ... The fully signed transaction gets propagated through the network via bitcoin nodes and hopefully get validated by a bitcoin miner shortly after.
Try these steps with a small amount of bitcoin until you become more comfortable.
That's really helpful. Once I've done it once or twice I'll be confident. I'm going to repost so other people know. Thanks again
