Setting up a Wallet

Initializing an ethers.js wallet constructed from a private Ethereum key.

The code snippet below returns an ethers wallet constructed from a private Ethereum key.

Note: For secure production environments, we recommend utilizing a secrets manager or vault to invoke the private key, instead of a plain-text environment variable.

function getWallet() {
  const privateKey = process.env.PRIVATE_KEY;
  if (!privateKey) {
    throw 'PRIVATE_KEY environment variable must be defined';
  }

  return new ethers.Wallet(privateKey);
}
