Truffle Smart Contract Documentation

Welcome to the documentation for Truffle, a powerful development framework for Ethereum and related technologies. This guide will help you get started with writing, testing, and deploying smart contracts using Truffle.

Getting Started

Before you dive into writing smart contracts, make sure you have the following prerequisites:

Writing Your First Smart Contract

To write a smart contract, you'll need to create a new Truffle project. Here's a simple example of a smart contract in Solidity:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract SimpleStorage {
    uint256 public storedData;

    function set(uint256 x) public {
        storedData = x;
    }

    function get() public view returns (uint256) {
        return storedData;
    }
}

Testing Your Smart Contract

Testing is a crucial part of the smart contract development process. Truffle provides a powerful testing framework to help you write and run tests for your contracts.

// test/SimpleStorage.test.js
const { expect } = require("chai");
const SimpleStorage = artifacts.require("SimpleStorage");

contract("SimpleStorage", function (accounts) {
    it("should store the value 42", async function () {
        const simpleStorage = await SimpleStorage.deployed();
        await simpleStorage.set(42);
        const result = await simpleStorage.get();
        expect(result).to.equal(42);
    });
});

Deploying Your Smart Contract

Once you've written and tested your smart contract, you can deploy it to the Ethereum network using Truffle's migration tools.

truffle migrate --network mainnet
