Hi again! I had a call to a developer and can advance in my API. This is an Node + Express API to consume Minter and Ledger canisters from a wallet, only for ckBtc transactions.
I already created addresses, and try to send some ckBtc from nns ic wallet and it already works. I try 2 transactions sending 1000 satoshis and both works, if i user de ledger icrc1_balance_of I get a response 2000n. But when i try to approve some amount to transfer, y get an “insufficient balance” and “balance: 0” for response.
What I am missing?
