Ethereum DeFi DEX Development
Budget: $25 – $50 USD
I’m building a fully‐on-chain decentralized exchange on Ethereum and need a developer who can take the project from smart-contract architecture to a clean, responsive front-end. The core of the platform is straightforward: seamless token swapping driven by automated market-maker logic, robust liquidity pool management, and an integrated staking mechanism that lets users earn protocol fees or governance tokens for locking their LP positions.
Here’s what I’m expecting:
• Smart contracts written in Solidity, audited internally for common vulnerabilities and optimized for gas efficiency.
• A web interface (React, Next.js or similar) that interacts with the contracts through ethers.js/web3.js, displaying real-time pool metrics and staking rewards.
• Subgraph or comparable indexing so users see up-to-date liquidity, volume and APY figures.
• Clear deployment scripts and documentation so I can spin up testnet and mainnet instances with minimal friction.
Acceptance criteria
• Swap transactions must settle on Ethereum mainnet with deterministic slippage and fee calculations matching the contract spec.
• Liquidity additions and removals should update pool balances instantly and emit verifiable events.
• Staking dashboard must show accrued rewards to the second and support claim/unstake in a single transaction.
• Full source code, README and a brief Loom/Zoom walkthrough delivered at hand-off.
If you’ve shipped AMM-based protocols before and are comfortable navigating the nuances of Ethereum gas, re-entrancy protection and front-end wallet connectivity, I’d love to see your approach and estimated timeline.
