Building Uniswap V2
Build the actual Uniswap V2 protocol from scratch. Every line of code. Modernized to Solidity 0.8.x. When you finish, you have a complete, deployable fork you understand because you wrote it.
What you are building
You will write the actual Uniswap V2 code: UniswapV2ERC20, UniswapV2Pair, UniswapV2Factory, UniswapV2Library, and UniswapV2Router02. Five contracts, modernized to Solidity 0.8.x. The architecture, math, and invariants are identical to the production protocol that handles billions in daily volume.

Fork ready, audit ready next
Built or forked Uniswap V2? Run a Krait readiness check before a full review.
Krait helps teams catch fork specific AMM risks in reserves, LP accounting, TWAP assumptions, router paths, and fee on transfer behavior before they ask Zealynx for a scoped audit.
