Tutorial: How to Send a Transaction in Moonbeam Using the Web3 Library with JavaScript

In this video, Alberto will explain how to send a transaction in Moonbeam using only the Web3 library and simple JavaScript code. Moonbeam is a Polkadot parachain (currently in active development) that is Ethereum-compatible, enabling integration with popular Ethereum DApps and tools like MetaMask, Remix IDE, Truffle Suite, and more.

For this video, you will need to have a local Moonbeam. If you haven't done that yet, you can find the tutorial here:

This tutorial was created using the pre-alpha release of Moonbeam. It also assumes an Ubuntu 18.04-based environment and will need to be adapted accordingly for MacOS or Windows.
