Web3.js

What is Web3.js?

Web3.js is a collection of tools that enable programmers to communicate with Ethereum nodes through HTTP, IPC, or WebSocket protocols using JavaScript. Dexfin has a similar API, which can be used with the same JSON RPC calls as Ethereum, allowing developers to utilize the Web3.js library to interact with a Dexfin node as if it were Ethereum.

Getting Started with Web3.js

1. Create a JavaScript Project to store all of the files you'll be creating

   mkdir web3-examples && cd web3-examples

2. Install the Ethers.js library and the Solidity compiler

   npm install web3 solc@0.8.0

3. Setup Web3.js with Caldera chain

   const Web3 = require('web3');
   
   // Create Web3 instance
   const web3 = new Web3("RPC URL"); // Insert your RPC URL here
