summary
• A keypair is a matching pair of public key and secret key.
• The public key is used as an “address” that points to an account on the Solana network. A public key can be shared with anyone.
• The secret key is used to verify authority over the account. As the name suggests, you should always keep secret keys secret.
• @solana/web3.js provides helper functions for creating a brand new keypair, or for constructing a keypair using an existing secret key.

- Using @solana/web3.js to make a keypair
npm i @solana/web3.js
import { Keypair } from "@solana/web3.js"; const keypair = Keypair.generate(); console.log(`The public key is: `, keypair.publicKey.toBase58()); console.log(`The secret key is: `, keypair.secretKey);

- Install
mkdir generate-keypair cd generate-keypair npm init -y npm install typescript @solana/web3.js esrun @solana-developers/helpers
import { Keypair } from "@solana/web3.js"; const keypair = Keypair.generate(); console.log(`✅ Generated keypair!`)
import "dotenv/config" import { getKeypairFromEnvironment } from "@solana-developers/helpers"; const keypair = getKeypairFromEnvironment("SECRET_KEY"); console.log( `✅ Finished! We've loaded our secret key securely, using an env file!` );
