Advanced Foundry
1. ERC20 Welcome To Advanced
A preparatory guide to Advanced Foundry - Prepare for deep dives into advanced Foundry features, building upon prerequisite knowledge. This introduction outlines the course scope, emphasizes best practices, and highlights the importance of these skills for advanced smart contract development. Duration: 1min
2. Introduction to ERC fundamentals and ERC20
A foundational overview to Understanding EIPs, ERCs, and the ERC-20 Token Standard - Explore Ethereum's proposal system (EIPs/ERCs) and dive into the crucial ERC-20 standard for fungible tokens. Learn its required smart contract interface, the goal of interoperability, and common extensions like ERC-677/777. Duration: 5min
3. Creating an ERC20
A practical guide to Building an ERC20 Token Manually with Foundry - Step through setting up Foundry and manually coding key ERC20 token functions like `name`, `decimals`, `totalSupply`, and `balanceOf`. Understand the underlying Solidity mechanisms and EIP-20 requirements by building from the ground up. Duration: 7min
4. Explore Open Zeppelin
A step-by-step guide to Implementing an ERC20 Token with OpenZeppelin and Foundry - Learn how to efficiently create ERC20 tokens by integrating the secure OpenZeppelin library into your Foundry project. Follow steps for installation, remapping configuration, contract inheritance, and minting initial tokens upon deployment. Duration: 5min
5. Deploy your ERC20 crypto currency
A practical guide to Deploying Your ERC20 Token with a Foundry Script - Learn how to create a basic `.s.sol` Foundry script to deploy an ERC20 token. Utilize `vm.startBroadcast`, deploy the contract to a local Anvil node, and simplify the workflow using a `Makefile`. Duration: 3min
6. Test your ERC20 using AI
A hands-on exploration of Writing and Understanding ERC20 Unit Tests with Foundry and AI Assistance - Master ERC20 unit testing in Foundry, covering setup, core function tests (`transfer`, `approve`), and `vm.prank` usage. Evaluate the benefits and pitfalls of using AI like Copilot/ChatGPT for accelerated test development, stressing the need for developer review. Duration: 15min
