Getting the correct Solana wallet address in TypeScript
In this article, we’ll look at how to get a valid Solana wallet address using TypeScript and the @solana/web3.js library.
Prerequisites
Before continuing, make sure you have the following installed:
- Node.js (version 16 or higher)
- Package
@solana/web3.js
- Solana CLI installation.
Import Dependencies
First, import the necessary dependencies:
import {key pair} from "@solana/web3.js";
import * as bip39 from "bip39";
import bs58 from "bs58";
// Import key pair functions to obtain the initial value based on the mnemonic
const DeriveKey = require('./deriveKey');
const generateSeedFromMnemonic = require('./generateSeedFromMnemonic');
// Import other service functions as needed
Getting the wallet address by mnemonic
To generate a wallet address using a mnemonic seed, we use the deriveKey function. This function takes an initial mnemonic and generates an instance of the key pair.
const mnemonic = 'mnemonic_seeds_from_here'; // Replace self with the actual mnemonic seed
// Generate an instance of a key pair from a mnemonic initial number
const keypair = DerivateKey(mnemonic);
Conversion of key pair to Solana wallet address
The Solana wallet address is represented as a URL-encoded string. We convert our keypair object to this format using the urlEncode function.
// Convert the Keypair instance to the Solana wallet URL
const WalletAddress = keypair.publicKey.url;
Authentication Check
To verify that the generated address is valid, we can use the isSolanaWalletAddress function from the @solana/web3.js library.
// Check if the generated address is a Solana wallet address
const isValid = isSolanaWalletAddress(walletAddress);
Connect all of this
Here is the full code example:
import {key pair} from "@solana/web3.js";
import * as bip39 from "bip39";
import bs58 from "bs58";
// Import key pair functions to obtain initial values based on mnemonics
const DerivEKey = require('./deriveKey');
const generateSeedFromMnemonic = require('./generateSeedFromMnemonic');
// Define a function for converting the Solana wallet address URL into an instance of a key pair
function toKeypair(url: string): keypair {
// Convert a URL-encoded string into an instance of a key pair
return DerivedKey(generateSeedFromMnemonic(mnemonic, url));
}
// Define a function to check the correctness of the generated address
function isValidWalletAddress(address: string): boolean {
ask {
const keypair = toKeypair(address);
// Check if the generated address is a Solana wallet address
return isSolanaWalletAddress(keypair.publicKey.url);
} catch (error) {
// Error handling or invalid input
console.error(error);
return a lie;
}
}
// Usage example:
const mnemonic = 'mnemonic_seeds_from_here'; // Replace self with the actual mnemonic seed
const WalletAddress = toKeypair(mnemonic);
if (isValidWalletAddress(walletAddress.publicKey.url)) {
console.log(Valid Solana wallet address: ${walletAddress.publicKey.url});
} more {
console.error('Invalid Solana wallet address');
}
This code example shows how to get the wallet address from a mnemonic seed, how to convert the generated key pair instance to a URL-encoded string, and verify that this is a valid Solana wallet address.
