Drawback. importmulti operate has lots of parameters and they’re tougher to understanding then the parameters of one other Bitcoin RPC-API capabilities. Those that should 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’s 2 wallets with the Bitcoin Core v.0.19.1:
wallet1 – the pockets with non-public key for export.
wallet2 – empty pockets into which we have to import the PK+deal with from wallet1.

So within the wallet1 we’ve got the bitcoin deal with created by getnewaddress.

I’ve tried to import that deal with to wallet2 however have failed.
