ERC20 Token Deployment Using Foundry

This project demonstrates how to create and deploy a simple ERC20 token using Foundry, a powerful toolkit for Ethereum application development.

Overview

This project includes:

• An ERC20 token contract
• A deployment script for easy token deployment
• Configuration for multiple networks (including Ethereum testnets)

Prerequisites

Before you begin, ensure you have the following installed:

• Foundry
• Git

Installation

1. Clone the repository:

   git clone https://github.com/your-username/erc20foundry.git
   cd erc20foundry
   

2. Install dependencies:

   forge install
   

Configuration

1. Create a .env file in the root directory with the following contents:

   PRIVATE_KEY=your_private_key_here_without_0x_prefix
   TOKEN_RECEIVER=0x_address_to_receive_initial_tokens
   RPC_URL=https://your-rpc-url
   ETHERSCAN_API_KEY=your-etherscan-api-key
   

   Replace the values with your actual private key, token receiver address, and RPC URL.

2. Load the environment variables:

   source .env
   

Compilation

Compile the contracts:

forge build

Testing

Run the tests:

forge test -vvv

Deployment

To deploy the ERC20 token:

forge script script/DeployErc20.sol:DeployERC20 --rpc-url $RPC_URL --private-key $PRIVATE_KEY --etherscan-api-key $ETHERSCAN_API_KEY --broadcast --verify -vvvv

This command will:

• Deploy the ERC20 token contract
• Transfer the initial supply to the specified receiver address
• Verify the contract on Etherscan (if supported by the network)

Contract Details

• Token Name: "TokenName"
• Token Symbol: "MyToken"
• Initial Supply: 1,000,000 tokens

You can modify these details in the ERC20Token.sol file.

Networks

This project is configured to work with multiple networks, including Ethereum testnets like Sepolia. Ensure you have the correct RPC URL in your .env file for the network you want to deploy to.

Security

• Never commit your .env file or expose your private keys.
• Ensure you're using a dedicated testnet account for development and testing.
