About this app
WHAT IT DOES
Arbitrage Opportunity Scanner helps you find profitable arbitrage opportunities across decentralized exchanges. You provide a list of token addresses, and the tool simulates price comparisons across DEX pairs (Uniswap, Sushiswap, Curve, Balancer, and custom pairs). It calculates price differences and reports potential profit percentages, indicating which tokens and exchanges offer arbitrage potential. This is essential for DeFi traders, arbitrageurs, and developers building trading strategies. It reads the current network chain ID from your wallet provider to ensure scans are directed to the correct chain.
HOW TO USE
Connect your wallet using the "Connect" button (required for RPC access). Select the target network (Ethereum Mainnet, Sepolia, Polygon, BSC, Arbitrum, Optimism, and testnets are supported). Enter token addresses (one per line) to scan. Optionally, specify custom DEX pairs in the format: dex1,dex2,address. Click "Scan for opportunities" — the tool will simulate price data and detect arbitrage opportunities, showing profit percentages and trade directions. The entire operation is read-only — no transactions are signed or sent.
TECHNICAL MECHANISM
The tool fetches token prices from DEX pairs using simulated or on-chain price data. It compares prices across pairs, calculating the price ratio between tokens. A price difference greater than 2% is flagged as a potential arbitrage opportunity. The tool uses ethers.js v5.7.2 to interact with the chain via the wallet's provider. All calls are view functions — no state is modified. The tool does not execute trades — it only scans and reports opportunities.
WHAT IT CANNOT SEE
The tool cannot guarantee that detected opportunities will be profitable after gas costs and slippage. It cannot account for MEV frontrunning or transaction ordering. It cannot detect cross-chain arbitrage. It is limited by RPC provider availability and DEX pair data freshness. It cannot execute trades — only scans and reports opportunities. It cannot account for liquidity depth or trade size limits. It cannot detect opportunities that require flash loans or complex multi-step paths without additional configuration.
PLEASE NOTE
This tool is for educational and research purposes. Always test arbitrage strategies with small amounts before committing significant capital. The tool does not persist any data; all state is lost on page reload. EVM chains only.
