Icon LinkCreating a wallet from mnemonic phrases

A mnemonic phrase is a cryptographically-generated sequence of words that's used to derive a private key. For instance: "oblige salon price punch saddle immune slogan rare snap desert retire surprise"; would generate the address 0xdf9d0e6c6c5f5da6e82e5e1a77974af6642bdb450a10c43f0c6910a212600185.

In addition to that, we also support Hierarchical Deterministic Wallets Icon Link and derivation paths Icon Link, allowing multiple wallets to be derived from a single root mnemonic. You may recognize a derivation path like:

"m/44'/60'/0'/0/0"

In simple terms, this structure enables the creation of multiple wallet addresses from the same mnemonic phrase.

The SDK gives you two wallets from mnemonic instantiation methods: one that takes a derivation path and one that uses the default derivation path, in case you don't want or don't need to configure that.

Here's how you can create wallets with both mnemonic phrases and derivation paths:

1 - Using the default derivation path m/44'/60'/0'/0/0

const mnemonic =
  'oblige salon price punch saddle immune slogan rare snap desert retire surprise';
 
const wallet = Wallet.fromMnemonic(mnemonic);

2 - Using a Custom Derivation Path

const mnemonic =
  'oblige salon price punch saddle immune slogan rare snap desert retire surprise';
 
const path = "m/44'/60'/1'/0/0";
 
const wallet = Wallet.fromMnemonic(mnemonic, path);
