lil-defi is a repro that deconstructs popular defi protocols and dapps to their core, inspired by lil-web3 from m1guel. Developed and tested with DappTools as an exploration into this library as an alternative to hardhat.
A very simple and limited adaptation of uniswap, built to deconstruct the protcol to it's barebones to understand how it functions
V3 maxis will note I ignored tick spacing/concentrated liquidity, but given the nature of this project, I excluded them for simplicity. The two contracts are intended to divide the logic appropriately, LilUniswap acts as the central contract (UniswapFactoryV3Factory), allowing the creation and deployment of token pools. LilUniswapPool represents the liquidity pools for each token pair and contains the logic for interacting with them.

A super simple smart contract wallet
lil smart wallet is a simple demonstration of how a smart contract can be used as a wallet. The observation here is that we can quite simply check owners of contracts + validate callers of functions.

A very limited MEV contract to explore how smart contracts can be used to capitalise on arbitrage oppurtunities between exchanges
