Building an ERC20 Token & Uniswap V2 Liquidity Pool with AI - BuidlGuidl's Builder Bootcamp

Date: Jul 2026
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.
