Struct Mnemonic 

pub struct Mnemonic { /* private fields */ }

A BIP-39 mnemonic phrase.

Implementations

impl Mnemonic

pub fn generate(word_count: usize) -> Result<Self, SignerError>

Generate a new random mnemonic with the given word count.

Supported counts: 12 (128-bit), 15 (160-bit), 18 (192-bit), 21 (224-bit), 24 (256-bit).

pub fn from_entropy(entropy: &[u8]) -> Result<Self, SignerError>

Create a mnemonic from raw entropy bytes.

Entropy length must be 16, 20, 24, 28, or 32 bytes.

pub fn from_phrase(phrase: &str) -> Result<Self, SignerError>

Parse a mnemonic phrase from a string.

Validates word count and checksum.

pub fn to_seed(&self, passphrase: &str) -> Zeroizing<[u8; 64]>

Convert the mnemonic to a 64-byte seed using PBKDF2-SHA512.

The passphrase is optional (use "" for no passphrase).

pub fn phrase(&self) -> &str

Return the mnemonic phrase as a string.

pub fn word_count(&self) -> usize

Return the number of words in the mnemonic.

pub fn to_ethereum_signer( &self, passphrase: &str, account_index: u32, ) -> Result<EthereumSigner, SignerError>

Derive an Ethereum signer from this mnemonic.

Uses BIP-44 path m/44'/60'/0'/0/{account_index}.

pub fn to_bitcoin_signer( &self, passphrase: &str, account_index: u32, ) -> Result<BitcoinSigner, SignerError>

Derive a Bitcoin signer from this mnemonic.

Uses BIP-44 path m/44'/0'/0'/0/{account_index}.

pub fn to_solana_signer( &self, passphrase: &str, account_index: u32, ) -> Result<SolanaSigner, SignerError>

Derive a Solana signer from this mnemonic.

Uses BIP-44 path m/44'/501'/{account_index}'/0'.

Note: Solana uses Ed25519, but BIP-32 derives secp256k1 keys. This returns the raw 32-byte derived key as the Ed25519 seed, which is the convention used by Phantom and other Solana wallets.

pub fn to_xrp_signer( &self, passphrase: &str, account_index: u32, ) -> Result<XrpEcdsaSigner, SignerError>

Derive an XRP ECDSA signer from this mnemonic.

Uses BIP-44 path m/44'/144'/0'/0/{account_index}.
