mnemonic seed – hierarchical deterministic wallets – creation of public keys

In BIP32 key derivation, having the parent extended public (xpub) key suffices for computing child public keys.

That parent xpub can be derived in a number of ways, but all eventually boil down to a seed. However, that seed is only used indirectly to construct the xpubs. Once you have the xpub, you can compute the child keys.
