Cross-Chain Arbitrage Bot with Smart Contract Execution -- 2

Job ID: 39144468

Budget: $750 – $1,500 SGD

Project Overview:

Please see attached image.

We are looking for an experienced blockchain developer to build a cross-chain arbitrage bot that can detect and execute profitable trades across decentralized exchanges (DEXs) on multiple blockchains.

The system should include:
1. An API to determine arbitrage opportunities.
2. A smart contract to execute buy and sell orders across different chains.

Bonus: Utilization of flash loans for capital efficiency is a significant advantage.

Requirements & Deliverables:

1. API for Arbitrage Detection
• Fetch real-time price data from multiple DEXs on different chains.
• Calculate arbitrage opportunities based on fees, slippage, and gas costs.
• Identify profitable trade routes between DEXs and chains.
• Provide API endpoints to expose detected opportunities in a structured format (e.g., JSON).

2. Smart Contract for Trade Execution
• Execute buy and sell orders on different chains.
• Handle cross-chain asset transfers efficiently.
• Optimize for gas fees and implement slippage protection.
• Integrate flash loans (if possible) to maximize arbitrage gains.

3. Cross-Chain Bridge Integration
• Implement or integrate with existing cross-chain bridges for asset movement.
• Ensure minimal delays and secure execution of trades.

4. Security & Testing
• Implement safety checks to prevent failed transactions or losses.
• Simulate trades before execution to confirm profitability.
• Code audit for security vulnerabilities and gas optimization.

Skills Required:
• Solidity & Smart Contract Development
• Web3.js / ethers.js
• Cross-chain communication protocols (e.g., LayerZero, Axelar, Wormhole)
• DEX Aggregators & Liquidity Pools
• Flash Loans & Gas Optimization
• API Development & Real-time Data Processing

Budget & Timeline:

Please provide an estimated budget and development timeline when applying. Preference will be given to developers with experience in DEX arbitrage, MEV strategies, and cross-chain trading.
