Complete Protocol

Key takeaway: This is the capstone of the Uniswap V2 reconstruction at Zealynx Academy. Five contracts complete: UniswapV2ERC20 (LP token + permit), UniswapV2Pair (AMM with TWAP and flash swaps), UniswapV2Factory (CREATE2 deploys), UniswapV2Library (helpers and fee math), UniswapV2Router02 (slippage, deadlines, multi-hop, FoT support). The full 217-test suite runs against your code and verifies every invariant (x * y >= k, MINIMUM_LIQUIDITY lock, _mintFee ordering, _update dual arithmetic). Pass them all and you have a deployable AMM that you understand line by line.

What You Built

You have written the entire Uniswap V2 protocol from scratch. Five contracts. Every function body. Every invariant. Every edge case handler. This is the same code that secures billions of dollars across hundreds of forks.

Here is what you built, contract by contract.
