Development Setup

Install prerequisites

Prepare Node.js 18+, a package manager, Git, and a wallet such as MetaMask.

Choose a framework

Hardhat setup

npx hardhat init
npm install --save-dev @nomicfoundation/hardhat-toolbox dotenv

Foundry setup

curl -L https://foundry.paradigm.xyz | bash
foundryup
forge init my-goat-project

Fund your wallet

On Testnet3, use the faucet. On mainnet, bridge or deposit BTC before attempting contract deployment, because BTC is also the native gas asset.

Deploy a test contract

contracts/HelloGOAT.sol

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.24;

contract HelloGOAT {
  string public message = "Hello, GOAT!";

  function setMessage(string memory nextMessage) external {
    message = nextMessage;
  }
}

First Deployment Commands

Hardhat deploy

npx hardhat run scripts/deploy.ts --network goatMainnet

Foundry deploy

forge script script/Deploy.s.sol \
  --rpc-url https://rpc.goat.network \
  --broadcast
