Overview

Package hdwallet implements SLIP-0010 hierarchical deterministic key derivation for Ed25519. Solana uses hardened-only derivation paths of the form m/44'/501'/0'/0'.

Types

type Key

type Key struct {
	PrivateKey []byte
	ChainCode  []byte
}

Key holds an Ed25519 private key and its chain code as produced by SLIP-0010 derivation.

func CKDPriv

func CKDPriv(key Key, index uint32) Key

CKDPriv performs SLIP-0010 hardened child key derivation. index must have the hardened bit set (index >= 1<<31).

func CreateMasterKey

func CreateMasterKey(seed []byte) Key

CreateMasterKey derives the master key from a BIP39 seed using the SLIP-0010 Ed25519 domain string "ed25519 seed".

func Derived

func Derived(path string, seed []byte) (Key, error)

Derived derives a child key from seed following path. path must be of the form m/44'/501'/0'/0' (all components hardened). Returns an error if the path is malformed.
