This is a production‑ready decentralized exchange developed from scratch and deployed independently. Core features include: - Swaps: Integrated with Uniswap V3 Router, supporting exact input/output swaps. - Liquidity Management: Add/remove liquidity, collect fees, query positions. The liquidity addition process involves real‑time pool data fetching and rendering of price range selectors, with dynamic calculations for position ticks and liquidity amounts. - Real‑Time Data: Backend polls pool data via The Graph and pushes updates to the frontend through WebSocket, avoiding RPC overload. Tech Stack: Next.js, TypeScript, Tailwind, Wagmi, Express, MongoDB, Hardhat, Solidity Deployment: Independent domain, fully tested on testnet, stable operation Code: 100% hand‑written, no template forks Website: https://app.bestdex-by-janessatech.com
