Dumpprivkey doesn't work for becuase it's not a legacy wallet, I can do dumpwallet and get something called a descriptor, how do I decode wif key from that if possible.
Use listdescriptors true command, find the proper descriptor for your addresses and find a way to import the descriptor to Sparrow.Since it's all TapRoot, it must be your "tr" descriptor that isn't 'internal' since that's for your change addresses.
For example, you're looking for:
Code:
"desc": "tr(xprv.../86'/0'/0'/0/*)#nnnnnnnn",
-snip-
"internal": false,
You can also use iancoleman's BIP39 tool to extract the private key based from the "master private key" (xprv) and derivation path included in the descriptor.
After exporting that from Bitcoin Core, it's altcoin territory and you might need to create a new topic in Altcoin Boards on how to spend it.
Thank you, I'll try that
