Initialize a new Node.js project (if you don't have one already):

mkdir solana-key-import
cd solana-key-import
npm init -y

Install required packages:

npm install @solana/web3.js bs58

Create a script to import the private key:

Create a file named importKey.js and add the following code:

const bs58 = require('bs58');
const { Keypair } = require('@solana/web3.js');

const privateKey = '4YFq9y5f5hi77Bq8kDCE6VgqoAqKGSQN87yW9YeGybpNfqKUG4WxnwhboHGUeXjY7g8262mhL1kCCM9yy8uGvdj7';

const keypairData = Keypair.fromSeed(Uint8Array.from(bs58.decode(privateKey).slice(0, 32)));

console.log('Public Key:', keypairData.publicKey.toString());
console.log('Secret Key:', keypairData.secretKey.toString());

Run the script:

node importKey.js

Export the private key for use with Solana CLI:

The Solana CLI expects the private key in a JSON file. You can generate this file by modifying your script slightly to save the secret key:

Update importKey.js:

const fs = require('fs');

const bs58 = require('bs58');
const { Keypair } = require('@solana/web3.js');

const privateKey = '4YFq9y5f5hi77Bq8kDCE6VgqoAqKGSQN87yW9YeGybpNfqKUG4WxnwhboHGUeXjY7g8262mhL1kCCM9yy8uGvdj7';

const keypairData = Keypair.fromSeed(Uint8Array.from(bs58.decode(privateKey).slice(0, 32)));

const secretKey = `[${keypairData.secretKey.toString()}]`;

fs.writeFileSync('keypair.json', secretKey);

console.log('Public Key:', keypairData.publicKey.toString());
console.log('Secret Key saved to keypair.json');

Run the script again:

node importKey.js

This will create a file named keypair.json with your secret key.

Import the keypair into Solana CLI:

Use the Solana CLI to set the keypair:

solana config set --keypair ./keypair.json

Now your Solana CLI is configured to use the imported keypair.
