Bitcoin Core change derivation path with getnewaddress cmd 0.17 As I'm building a simple HD wallet, I would like to use bitcoin core regtest. My goal is to setup a testing flow where I could have constant seeded address each time I use bitcoin-testnet-box, so that I could cross-check derivated addresses amongst other tests.

Using bitcoin-cli sethdseed and getnewaddress is the way, but I can't figure a solution to derivate child keys using another path than the default bitcoin core's one which seems to be m/0'/0'/i'.

Is there a way to change derivation path in a custom way ?
No. Bitcoin Core currently does not allow you to use a different derivation path.
