Struct Bip39Account 

pub struct Bip39Account { /* private fields */ }

A BIP-39 compatible neo account that uses mnemonic phrases for key generation and recovery.

This implementation follows the BIP-39 standard for generating and recovering neo accounts using mnemonic phrases. The account can be created with a new random mnemonic or recovered from an existing mnemonic phrase.

Examples

Creating a new account

use neo3::neo_wallets::Bip39Account;

// Create a new account with a password
let password = "your_secure_password";
let account = Bip39Account::create(password).unwrap();

// The account will have a randomly generated 24-word mnemonic
let _mnemonic = account.mnemonic().to_string();
// SECURITY: Store the mnemonic securely offline. Avoid logging it.

Recovering an existing account

use neo3::neo_wallets::Bip39Account;

// Recover an account using an existing mnemonic and password
let mnemonic = "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon art"; // Your 24 word mnemonic
let password = "your_secure_password";
let recovered = Bip39Account::from_bip39_mnemonic(password, mnemonic).unwrap();

Implementations

impl Bip39Account

pub fn mnemonic(&self) -> &str

Returns the mnemonic phrase used for this account

pub fn account(&self) -> &Account

Returns a reference to the underlying Neo account

pub fn create(password: &str) -> Result<Self, Box<dyn Error>>

Creates a new BIP-39 compatible neo account with a randomly generated mnemonic.

The private key for the wallet is calculated using: Key = SHA-256(BIP_39_SEED(mnemonic, password))

The password is used as a BIP-39 passphrase and is required to recover the account later. The same password must be provided during recovery to generate the same keys.

Arguments

• password - The passphrase used in BIP-39 seed generation. This must be saved to recover the account.

Returns

A Result containing the new Bip39Account or an error if creation fails.

Example

use neo3::neo_wallets::Bip39Account;

let account = Bip39Account::create("my secure password").unwrap();
// Save the mnemonic securely
let mnemonic = account.mnemonic().to_string();

pub fn from_bip39_mnemonic( password: &str, mnemonic: &str, ) -> Result<Self, Box<dyn Error>>

Recovers a neo account from an existing BIP-39 mnemonic phrase and password.

This method will reconstruct the exact same neo account if provided with the same mnemonic and password combination that was used to create the original account.

Arguments

• password - The same passphrase that was used when generating the original account
• mnemonic - The 24-word mnemonic phrase from the original account

Returns

A Result containing the recovered Bip39Account or an error if recovery fails

Example

use neo3::neo_wallets::Bip39Account;

let mnemonic = "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon art"; // Your saved 24-word mnemonic
let password = "your_secure_password";      // Original password used
let account = Bip39Account::from_bip39_mnemonic(password, mnemonic).unwrap();

Trait Implementations

impl Debug for Bip39Account

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

Formats the value using the given formatter.

impl Drop for Bip39Account

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
