This session provides a fast-paced, practical demonstration of leveraging AI (Cursor with Claude Sonnet 4.5) to accelerate Web3 development using the Scaffold ETH framework. The demo quickly moves from setting up a local blockchain and debugging a simple smart contract to defining a "Max Extract" ERC20 token, implementing ownership and transfer logic, and finally integrating a live token sale contract with a Uniswap V2 liquidity pool, testing the entire system on a forked Base network. š To learn everything about building on Ethereum, go to https://speedrunethereum.com/ -------- 0:00 Week Recap: From First App to Zero Knowledge Proofs 0:01:26 Essential Curriculum: Why Speedrun Ethereum is the Best Way to Learn 0:02:27 Key Tool Introduction: Scaffold ETH & Starting the Live Build with AI 0:03:05 Using Cursor with Claude Sonnet 4.5 in Agent Mode 0:03:38 Reviewing the Example Greeter Smart Contract 0:04:18 Debugging: Interacting with the Contract on the Auto-Adapting Front End 0:05:03 Live Coding Demo: Building a Simple Counter with an Owner Check 0:06:54 EVM Lesson: Why Solidity Doesn't Use Decimals 0:07:48 Implementing the "Fake Decimal System" (Using 10^18 for ETH Values) 0:08:36 Security Testing: Using an Incognito/Attacker Wallet to Test Access Control 0:09:58 Setting Up the Hackathon Project: ERC20 Token & Token Sale Idea 0:10:24 Defining the Token: Creating the "Max Extract" Ownable ERC20 0:11:45 Defining the Tokenomics: Treasury, Buy Backs, and Burning Tokens 0:12:56 Explaining AI Modes: Ask Mode vs. Plan Mode vs. Agent Mode 0:15:38 Debugging with AI: The Iterative Process of Prompting and Fixing Bugs 0:17:42 Demoing Token Transfer (Sending Max Extract to 'Vitalic') 0:20:05 Planning the Token Sale: Locking ETH for a Future Treasury Contract 0:22:27 Building the TokenSale.sol Contract 0:24:20 Q&A: Hardhat vs. Foundry in Scaffold ETH 0:26:22 Next Big Feature: Integrating a Uniswap V2 Liquidity Pool 0:28:31 Prompting AI: Generating the Button to Add Uniswap V2 Liquidity 0:31:11 Asking the AI to Calculate Liquidity Ratio ("You're the Math Machine") 0:32:39 Testing on a Fork: Preparing for Live Deployment on Base Network 0:34:41 Deploying to the Base Fork and Testing Token Purchase 0:36:41 Planning to Go Live: Final Steps and Scaling Down Values for Production Testing --------
