How important is the finger print? I tried to compute the fingerprint, but mine was not the same as the one sparrow shows. Probably due to the fact that it show the Master Fingerprint.
It's not too important when it comes with the watch-only wallet's functions since it can derive public keys and create unsigned transactions without it.
It's mainly a requirement of hardware wallets to verify that you're using the correct signer.
Because it's computed (
hashed) from the master private key itself.
Here's how to actually compute it:
/index.php?topic=5444628.msg61903879#msg61903879You need another tool to separate the private key from the chain code of your master private key (
xprv),
and it has to be the "
m" and not any other child xprv derived from it.
