Create Wallet

Creates a new Solana wallet (more specifically a KeyPairSigner).

If you like, the wallet will have a prefix/suffix of your choice, the wallet will have a SOL balance ready to spend, and the keypair will be saved to a file for you to use later.

Returns: Promise<KeyPairSigner>


const wallet = await connection.createWallet({
  prefix: "be", // Optional: Generate address starting with these characters
  suffix: "en", // Optional: Generate address ending with these characters
  envFileName: ".env", // Optional: Save private key to this .env file
  envVariableName: "PRIVATE_KEY", // Optional: Environment variable name to store the key
  airdropAmount: 1_000_000_000n, // Optional: Amount of test SOL to request from faucet
});

Options

All options are optional:

prefix: string | null - Prefix for wallet address
suffix: string | null - Suffix for wallet address
envFileName: string | null - Path to .env file to save keypair
envVariableName: string - Name of environment variable to store keypair (default: “PRIVATE_KEY”)
airdropAmount: Lamports | null - Amount of SOL to airdrop (default: 1 SOL)
