Cross-Chain Arbitrage Bot with Smart Contract Execution
Budget: $750 – $1,500 SGD
Project Overview:
I am looking for an experienced blockchain developer to create a cross-chain arbitrage bot that can detect and execute profitable trades across different decentralized exchanges (DEXs) on multiple blockchains.
The system should include:
1. An API to determine arbitrage opportunities
2. A smart contract to execute the buy and sell across different chains
Utilization of flash loans for capital efficiency will be 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
• Provide API endpoints to expose detected opportunities
2. Smart Contract for Trade Execution
• Execute buy and sell orders on different chains
• Handle cross-chain asset transfers efficiently
• Optimize gas fees and 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 and gas optimization
Preferred Experience:
• Solidity & smart contract development
• Cross-chain bridge integrations (e.g., LayerZero, Wormhole, Axelar, Celer)
• DEX aggregators and on-chain data fetching
• Experience with flash loans (Aave, dYdX, UniswapX, etc.)
If you have experience with Ethereum, BSC, Solana, or other EVM-compatible chains, that would be a plus.
Budget & Timeline:
• Please provide your estimated timeline and cost breakdown.
• Include relevant past work examples or GitHub repositories.
Looking forward to your proposals!
