A script to generate random 12 words mnemonic and checking balances

Generate random addresses and check balances

A script that generates random 12 words mnemonic, derives the address and check for balance.

How to use it

• Run npm i

• Create a .env file in the root directory
  The env file should look like this (the Sendgrid api key is not mandatory):

  ETHEREUM_PRC_NODE =
  SENDGRID_API_KEY =

• If the Sendgrid api is set, you must set the sender and the receiver email addresses (modules/sendgrid)

this.message = {
  to: null,
  from: null,
  subject: '[Wallet Scan Script] - New wallet found',
  text: '',
}

• Run npm start

In case a valid wallet is found

The wallet information (mnemonic, address, amount of tokens held) is displayed in the console.
If the Sendgrid API key is set, the script sends an email.
