Experienced Web3 & Frontend Developer Needed to Build Polygon-based DEX
Budget: $15 – $25 USD
I’m looking for an experienced Web3 and frontend developer to collaborate on a long-term project: building a decentralized exchange (DEX) on the Polygon network, similar to PancakeSwap.
What You’ll Do:
Fork the PancakeSwap codebase
Deploy and configure the exchange protocol on Polygon
Build a modern, performant frontend (React/Next.js preferred)
Work with and integrate smart contracts for swaps, farms, pools, and governance
Ensure complete Web3 wallet integration (Metamask, WalletConnect, etc.)
Maintain and extend the protocol over time
What You Must Have:
Proven experience with Web3 development (ethers.js/web3.js, Solidity, hardhat/foundry)
Strong frontend development skills using React, Next.js, or Vue
Experience deploying and testing DEX protocols
Deep understanding of EVM-compatible chains (especially Polygon & BSC)
Ability to independently deploy, debug, and test smart contracts
Technical Test:
To filter for real experts, please complete this small task as part of your application:
Fork and deploy the PancakeSwap exchange protocol:
https://github.com/andrewbaxter225/exchange-protocol
Deploy the smart contracts on BSC Testnet
Compare your deployment with the real PancakeSwap protocol (identify any key differences or limitations)
This task will demonstrate your understanding of the codebase and smart contract deployment.
