Blockchain Development Programming Tutorials, Guides & Best Practices

    const { ethers } = require('ethers');
    const randomBytes = ethers.utils.randomBytes(32);
    console.log(randomBytes); // Uint8Array of random bytes

• crypto.randomBytes is part of Node.js, so it requires no external dependencies. This makes it ideal for Node.js environments where minimal dependencies are desired.
• ethers.randomBytes requires the installation of the ethers.js library, which is primarily designed for blockchain-related projects. This is useful if you're already working with Ethereum, but it adds an external dependency to the project.

Once you’ve added the code, run the script:

node getTokenBalance.js

By the end of this tutorial, you will be able to send Ether, call smart contract functions, and deploy contracts using Infura as your provider.

To follow along with this tutorial, you’ll need:

Run the following command in your project folder to install it:

npm install ethers

and reactive Java and Android library for working with smart contracts and integrating with Ethereum nodes.
