I believe this will reduce robustness and will add complexity to the test software instead. If the derivation path is hardened in 'production code' and is unhardened in 'test code', then: code paths that depend on hardened derivation may not be tested; there will be unnecessary code that will need to deal with 'un-hardening' the paths for test code. It is much more robust to just change the 'purpose' part of the path, and leave the rest unchanged. It is OK to require privkey access to hardened paths in test software, because the same behaviour is expected in 'production'. _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
