Struct Wallet 

pub struct Wallet { /* private fields */ }

A unified HD wallet that can derive keys for multiple cryptocurrencies.

This wallet holds a BIP39 mnemonic and derives a seed that can be used to generate addresses for Bitcoin, Ethereum, and other coins following BIP32/44/49/84 standards.

Passphrase Support

The wallet supports an optional BIP39 passphrase (sometimes called “25th word”). This provides an extra layer of security - the same mnemonic with different passphrases will produce completely different wallets.

Implementations

impl Wallet

pub fn from_entropy( entropy: &[u8], passphrase: Option<&str>, ) -> Result<Self, Error>

Create a wallet from raw entropy bytes.

This is useful in no_std environments where you provide your own entropy source instead of relying on the system RNG.

Arguments

• entropy - Raw entropy bytes (16, 20, 24, 28, or 32 bytes for 12-24 words)
• passphrase - Optional BIP39 passphrase for additional security

Errors

Returns an error if the entropy length is invalid.

pub fn from_mnemonic( phrase: &str, passphrase: Option<&str>, ) -> Result<Self, Error>

Create a wallet from an existing mnemonic phrase.

Arguments

• phrase - BIP39 mnemonic phrase
• passphrase - Optional BIP39 passphrase

Errors

Returns an error if the mnemonic is invalid.

pub fn mnemonic(&self) -> &str

Get the mnemonic phrase.

Security Warning: Handle this value carefully as it can reconstruct all derived keys.

pub fn seed(&self) -> &[u8; 64]

Get the seed bytes for key derivation.

This seed can be used by chain-specific derivers (Bitcoin, Ethereum, etc.) to generate addresses following their respective standards.

pub const fn has_passphrase(&self) -> bool

Check if a passphrase was used to derive the seed.

pub fn word_count(&self) -> usize

Get the word count of the mnemonic.

Trait Implementations

impl Debug for Wallet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
