Build Your Own Decentralized Token Exchange with Smart Contracts

Centralized exchanges control funds and charge high fees. A decentralized exchange gives users full control over their assets, allows peer-to-peer token trading, and removes middlemen by using automated smart contracts.

Create a DEX platform with token swapping, liquidity pool creation, and AMM logic. Users can provide liquidity, earn fees, or swap tokens seamlessly. The platform should be fully non-custodial, transparent, and open to anyone with a Web3 wallet.

The exchange uses a factory contract to deploy liquidity pools for token pairs. A router contract manages swaps, liquidity additions, and fee calculations. The frontend interacts with these contracts via Web3, providing a seamless swap experience.

• Factory Contract: Creates and tracks token pair pools
• Router Contract: Manages token swaps, LP additions, and withdrawals
• ERC-20 Compatible Token Contracts
• Frontend: Token selector, price chart, slippage tolerance UI, and pool analytics
• Wallet Integration via MetaMask or WalletConnect

• Uniswap v2 Core Contracts
• Uniswap Router Logic
