Foundry

In this tutorial, we'll walk through creating a basic Foundry project.

Here's a video walkthrough:

Prerequisites​

Before you begin, Ensure you've:

  1. Set up your wallet

  2. Funded your wallet with Linea ETH

    curl -L https://foundry.paradigm.xyz | bash

    Then, open a new terminal, and call foundryup to install the latest release.

Create a Foundry project​

To create an empty Foundry project, run:

forge init linea-tutorial

And change into the directory:

cd linea-tutorial

Write the smart contract​

Running forge init sets you up with a sample contract, test, and script for Counter.sol. To build it, simply run forge build.

Deploy the smart contract​

To deploy a smart contract, we highly recommend using an Infura endpoint, as the public endpoint may experience rate limiting. You can find out how to get an API key here. Then, you can run the following command.

Using Infura:

forge create --rpc-url https://linea-goerli.infura.io/v3/YOUR-INFURA-API-KEY src/Counter.sol:Counter --private-key YOUR_PRIVATE_KEY

Using the public endpoint:

forge create --rpc-url https://rpc.goerli.linea.build/ src/Counter.sol:Counter --private-key YOUR_PRIVATE_KEY

Your output should look a little something like this:

Deployer: YOUR_ACCOUNT_NUMBER
Deployed to: 0xED0Ff7E8B655dFFfCA471ea3B6B649ce7C2C1b83
Transaction hash: 0x967e1290b285e67b3d74940ee19925416734c345f58bd1ec64dcea134647d7ee

Next, you can optionally verify your contract on the network.
