  • ethers.randomBytes:
  • Library: ethers.randomBytes is provided by the ethers.js library, a popular JavaScript library for Ethereum development. You need to install and include ethers.js as a dependency in your project to use this function.
  • Usage: This function optionally takes the number of bytes you want to generate. If no argument is passed, it defaults to generating 32 bytes. It returns a Uint8Array of random bytes.
  • Example:
    const { ethers } = require('ethers');
    const randomBytes = ethers.utils.randomBytes(32);
    console.log(randomBytes); // Uint8Array of random bytes
