public final class Slip10
- Object
- Slip10
SLIP-10 key derivation for Ed25519, the scheme Solana, Stellar, Cardano-style and
Aptos/Sui wallets use on a Mnemonic seed. Ed25519 has no public derivation, so every
index is hardened: m/44'/501'/0'/0' is the usual Solana account.
(SLIP-10 over secp256k1 is BIP-32 itself; use Bip32 for that curve.)
Methods
public static Slip10 master(byte[] seed) | The master node of a seed (16 to 64 bytes). |
public Slip10 child(long index) | The hardened child at index. |
public Slip10 derive(String path) | Derives along a path such as m/44'/501'/0'/0'. |
public Slip10 derive(DerivationPath path) | Derives along a path; every index is taken as hardened. |
public byte[] privateKey() | A copy of the 32-byte Ed25519 private key (the RFC 8032 seed). |
public byte[] publicKey() | The 32-byte Ed25519 public key. |
public byte[] chainCode() | A copy of the 32-byte chain code. |
public int depth() | The distance from the master node. |
public long childNumber() | The hardened index this node was derived with. |
public int parentFingerprint() | The parent’s fingerprint; 0 for the master node. |
public int fingerprint() | The first four bytes of HASH160(0x00 || publicKey), as SLIP-10 defines it. |
public void destroy() | Wipes the private key and chain code. |

Method details
master
public static Slip10 master(byte[] seed)The master node of a seed (16 to 64 bytes).
child
public Slip10 child(long index)The hardened child at
index. An index below DerivationPath.HARDENED is hardened
for you, since Ed25519 has no other kind.derive
public Slip10 derive(String path)Derives along a path such as
m/44'/501'/0'/0'.derive
public Slip10 derive(DerivationPath path)Derives along a path; every index is taken as hardened.
privateKey
public byte[] privateKey()A copy of the 32-byte Ed25519 private key (the RFC 8032 seed). Wipe it after use.
publicKey
public byte[] publicKey()The 32-byte Ed25519 public key.
chainCode
public byte[] chainCode()A copy of the 32-byte chain code.
depth
public int depth()The distance from the master node.
childNumber
public long childNumber()The hardened index this node was derived with.
parentFingerprint
public int parentFingerprint()The parent’s fingerprint; 0 for the master node.
fingerprint
public int fingerprint()The first four bytes of
HASH160(0x00 || publicKey), as SLIP-10 defines it.destroy
public void destroy()Wipes the private key and chain code.
