 Cardano hierarchical deterministic wallets use an extended private key which requires them to implement a custom adaptation of the BIP-0032 child key derivation scheme. The Cardano wallets currently in existence implement several mutually incompatible schemes for the derivation of the master node from a BIP-0039 mnemonic and passphrase. Unfortunately all of these derivation schemes fail to separate the derivation of the seed from the derivation of the key tree, making it impossible to integrate them with new seed derivation schemes. This specification aims to rectify this by defining a new scheme for the derivation of the master node from a seed. The new scheme is primarily intended for use with SLIP-0039 Shamir's Secret-Sharing for Mnemonic Codes.

 This scheme adapts the master node derivation used in BIP-0032 and SLIP-0010 by defining a new curve name "ed25519 cardano seed" for the Ed25519 curve with the Cardano deterministic key hierarchy. The curve name is used as salt in BIP-0032 and SLIP-0010 when deriving the master node from the seed. This is necessary to ensure proper domain separation between different elliptic curves or different types of key hierarchies. The root extended private key (*k*<sub>L</sub>,&nbsp;*k*<sub>R</sub>) is computed by taking the SHA-512 hash of the root private key *I*<sub>L</sub>, modifying certain bits to make it a valid EdDSA key and clearing the third highest bit of *k*<sub>L</sub> to ensure compatibility with Cardano child key derivation.
