Anvil Foundry Testing

This is a a project to demonstrate my understanding of how to fork a chain and deploy smart contracts using Anvil (Foundry's local Ethereum node) and viem.

Prerequisites

• Node.js (v16 or higher)
• npm or yarn
• Foundry (for Anvil)

git clone https://github.com/cortisiko/anvil-foundry-blockchain-testing.git
cd anvil-foundry-testing

2. Install dependencies:

npm install

3. Install foundry:

yarn install-foundry

The project includes a sample ERC20 token deployment:

• Name: CurtToken
• Symbol: CURT
• Decimals: 4
• Initial Supply: 10
