Distinct public keys per account can be guaranteed by using distinct hardened derivation paths. This specification does not mandate hardened derivation in order to maintain compatibility with existing deployments that do not adhere to this recommendation. It is out of scope for this document to guarantee that users do not reuse extended public keys among different wallet accounts. This responsibility is left to the users and their software wallet. |
