Call smart contract functions using web3.js

This simple project shows how to interact with a smart contract using the JavaScript library web3.js.

Find the code showcasing how to call a view/pure function from a smart contract in the index.js file.

The contract directory holds the smart contract used for this project.

• In this case, it is a simple smart contract that allows a user to store and retrive a string.

Requirements

• Node.js
• Access to an Avalanche Fuji testned node

Quickstart

Deploy an Avalanche Fuji node

1. Sign up with Chainstack.
2. Deploy a node.
3. View node access and credentials.

Clone the repo.

git clone https://github.com/soos3d/Call-smart-contract-functions-using-web3.js.git

Install dependencies.

npm i

Setup .env file

1. Rename the .env.sample file to .env.
2. Add the Chainstack Avalanche Fuji endpoint.

Run the script

node index.js

This script works out of the box because the smart contract is already deployed.

Use on any smart contract

To use this script for another smart contract, edit the following:

• The abi variable.

const abi = [ADD_THE_NEW_ABI]

• The smart contract address.

const address = "NEW_ADDRESS"

• Replace with the new function's name.

contract.methods.aFunction().call
