I’ve exported my xpub from bluewallet and generated a few derived addresses from it using invoice numbers as derivation indexes. Then I sent a few sats to one of those address as a test. As I’m new learning this technology, I got surprised because the wallet didn’t show the balance. I made a small research and realized that the wallet doesn’t monitor all the addresses derived from my xpub, it only tracks incoming transactions for 20 addresses by default.
Said that I have a few questions:
1- To maintain a record of the real balance, should I request a Bitcoin/API node asking for info related to each derived addresses?
2- There’s any wallet I can use to monitor specific derived addresses and allows me to spend that balance?
3- How can I spend that balance without a wallet or compromising my seed?
Context: I’m learning how to process Bitcoin payments with nodejs.
Thanks so much in advance!
