Solana: How do derive a keypair from mnemonic using web3.js v2?

Keying the keyboard with mnemonic using web3.js v2

The Mnemonic phrase using the web3.js v2 library. We will also discuss the equivalent implementation in Typescript.

Preliminary Requirements

Before you start, make sure you have:

Set the Solan Environment with a Portfolio provider (e.g. metamask).

Download the keyyair-sign.d.ts from the official solana website: <

Read the Web3.js v2 Library.

Keying the keyboard with mnemonic

Mnemonic phrases are safe and can be used to obtain keyboards. Here is an example of implementation:

`Typescript



Import {mnemonictoseed, mnemonicseed} with "@solana/web3.js";

Import {keyyair} z "./ keypair-signer.d.ts";

Const Mnemonic = "Your-Manemonic-Faza"; // replace with your mnemonic phrase

// Equip the keyboard with mnemonic seeds

Const keyyair = new keypair ();

Const Mnemonica Seeds = Mnemonactoseed (Mnemonic, Mnemonica);

Keypair.privatey = mnemonica;

Equivalent Implementation in Typescript

Unfortunately, there is no direct equivalent of keyyair.fromseed () in the keyyair-signer.d.tsfile. However, we

Typescript



Import {mnemonictoseed} with "@solana/web3.js";

Import {keyyair} z "./ keypair-signer.d.ts";

Const Mnemonic = "Your-Manemonic-Faza"; // replace with your mnemonic phrase

// move to the keyboard with the help of manually mnemonic seed

DeriveKeyPair Function (Mnemonicseed: String): Keypair {

  Const private = keyyair.generatefromseed (Mnemonicseed, {Length: 32});

  Return Keyey;

}

Const keyyair = derivkeypair (Mnemmonictoseed (Mnemonic, Mnemonictoseed));

`To create a new "keyboard" instance from seeds.



 With Web3.js V2 


By using web3.js v2, you can lead the keyboard out of the mnemonic

Typescript



Import {mnemonictoseed} with "@solana/web3.js";

Import {keyyair} z "./ keypair-signer.d.ts";

Const Mnemonic = "Your-Manemonic-Faza"; // replace with your mnemonic phrase

// Equip keyboard using mnemonic functions and web3.js

Async Derivkeypair Function () {

  Const privateys = wait for the promise. All ([[

    New Keypair (). Privatey,

    New Keypair (). Secretkey,

  ]);

  Return Private Keys;

}

Const keypairs = wait for derivekeypair ();

In Then we print the resulting keyboard for further processing.

By following these steps, you should be able to lead the keyboard out of the mnemonic phrase using web3.js v2.
