Dex Explorer V2 Script May 2026
Building a DEX Explorer V2 Script: Real-Time Liquidity & Arbitrage Analysis
4.2 Multichain Interoperability
V2 is chain-agnostic. The configuration file allows the operator to toggle chains on or off.
- Supported Chains: Ethereum, Binance Smart Chain (BSC), Base, Arbitrum, Polygon.
- Mechanism: The script spawns a separate listener instance for every active chain defined in
config.json.
5. Smart Contract SDK Integration
Read-only is dead. V2 scripts come with built-in transaction builders. Users can click "Swap" inside the explorer, and the script generates the calldata required to execute the trade via their wallet (WalletConnect/MetaMask). dex explorer v2 script
Core Logic Flow
- User Input → Network, DEX list, token pairs
- Contract Loading → Load factory, router, pair ABI
- Data Fetching → Query reserves, total supply, fee tier
- Price Calculation
- V2:
price = reserve1 / reserve0
- V3: sqrtPriceX96 → decimal conversion
- Arbitrage Check
- Compare prices across DEXs on same chain
- Filter by min profit threshold after gas estimate
- Output → Console table + JSON export
8. Alerting rules (examples)
- High severity:
- Liquidity removal > 50% within 1 hour.
- Owner blacklisted or transfer to known exploit address.
- Medium:
- Single swap > $100K causing >10% price impact.
- New token with 90%+ supply held by single address.
- Low:
- Sustained abnormal volume spikes (>3x 24h avg).
- Repeated small swaps between same set of addresses.
