In this project video, I’m building and deploying a 100% custom decentralized exchange from scratch—no theory fluff, just real code and a real production-style DApp. Users can launch their own token, create pools, add liquidity, remove liquidity, and swap tokens while tracking every trade happening inside the liquidity they created. The key point: every single contract in this project is independent and custom—router, factory, pair, token factory, and even the quotation/pricing logic—so you’re not just “forking” something and calling it a DEX. I walk you through the full UI like a real exchange: dashboard stats, tokens list, pools + pool detail pages (TVL, fees, swaps, graphs), transactions explorer, swap screen with slippage control, and a liquidity manager where you can add/remove liquidity with full control. I also show the documentation section where anyone can copy contract addresses, ABIs, and integrate the router/factory/pair like an SDK-style setup. Finally, I show you how to set up the full codebase locally (Node, Hardhat local node, env variables, deploy scripts, and project architecture) so you can test everything end-to-end and then deploy to Ethereum, BNB, Polygon, Avalanche—any EVM network.
