It supports BIP32 keys, WIF, and addresses (bitcoin and alt coins). This implementation supports ed25519. For convenience, each keychain may have a label. Since the recovery phrase is the seed from which every xPub’s corresponding xPriv (extended private key) is derived, all of the private keys of all addresses derived within the wallet are contained within it. Because the child key is generated from a known seed there is a relationship between the child and parent keys that is invisible to anyone without that seed. We’re getting somewhere.
