bitcoin core – The way to import handle with personal key utilizing importmulti

Downside. importmulti operate has lots of parameters and they’re harder to understanding then the parameters of one other Bitcoin RPC-API features. Those that are usually not profi in trendy cryptographic achievements have troublesome with understanding how one can use importmulti operate.

Right here is the duty that demonstrates the issue.
There may be 2 wallets with the Bitcoin Core v.0.19.1:
wallet1 – the pockets with personal key for export.
wallet2 – empty pockets into which we have to import the PK+handle from wallet1.

So within the wallet1 now we have the bitcoin handle created by getnewaddress.
