DEX Tools – Uniswap V3 & GluwaDEX Deployment

🔭 Overview

A comprehensive deployment toolkit and CLI for managing DEX smart contracts — covering both the full Uniswap V3 protocol stack and the custom GluwaDEX (SwapPool V1/V2, SwapRouter). Designed for reliable, repeatable deployments across local Docker environments, testnet, and production networks.

🛠️ What I Built

💱 Uniswap V3 Full Protocol Deployment

  • 🏭 Complete Uniswap V3 deployment: UniswapV3Factory, UniswapV3Pool, SwapRouter, NonfungiblePositionManager, NonfungibleTokenPositionDescriptor, QuoterV2
  • ⚙️ Deployment scripts with configurable fee tiers, tick spacing, and initial pool parameters
  • ✅ Post-deployment validation: verifies pool creation, fee configuration, and position manager linkage
  • 💧 Liquidity provision scripts for initializing pools with seed liquidity

🔄 GluwaDEX Deployment

  • 📜 SwapPool V1 and V2 contract deployment with configurable fee parameters
  • 🔀 SwapRouter deployment and integration with pool registry
  • 🔄 Migration scripts for V1 → V2 pool upgrades
  • ⚙️ Administrative scripts for fee updates and pool pausing

⌨️ CLI Tool

  • 💬 Interactive CLI for common DEX operations: create pool, add liquidity, swap, collect fees
  • 🌐 Supports local Docker environment, testnet, and mainnet via --network flag
  • 📋 Human-readable output with transaction hashes, gas costs, and resulting state

🐳 Docker-Based Local Test Environment

  • 🐳 Docker Compose with local Hardhat node + deployed DEX contracts
  • 🌱 Pre-seeded with test tokens, liquidity pools, and funded test wallets
  • 🔄 Deterministic: same environment every time, no state drift between test runs

🧪 Integration Test Suite

  • 🔄 End-to-end tests covering: pool creation → liquidity provision → swap execution → fee collection
  • 📊 Price impact validation: verifies swap outputs match Uniswap V3 price math
  • 🔀 Multi-hop swap tests through multiple pools
  • ✅ Invariant tests: pool invariant (x*y=k) holds after all operations

⭐ Key Highlights

  • 🏭 Full Uniswap V3 protocol stack deployed and validated in a single command
  • 🐳 Docker-based deterministic test environment eliminates "works on my machine" issues
  • ⌨️ CLI tool enables non-engineer team members to interact with DEX contracts safely
  • 🧪 Integration tests validate complete swap lifecycle from pool creation to fee collection
