Can anyone point me to working implementations of BIP85?

The only one I'm aware of is the Coldcard Wallet implementation.

As of today (2020-08-13) there are seem to be none. I've opened some tickets. Hopefully developers find some time to implement.


check out https://github.com/scgbckbone/btc-hd-wallet

Besides the iancoleman app, as of 2022-02 I only know of Coldcard & AirGap Vault.

See the spec for libraries
