Introduction
Decentralized exchanges (DEXs) on Ethereum have revolutionized trading by eliminating intermediaries. However, effectively monitoring DEX activity requires strategic tools and methodologies. This guide explores practical approaches to track transactions, liquidity, and trends on ETH-based DEX platforms.
Key Methods for DEX Monitoring
1. Smart Contract Event Listening
- Purpose: Capture real-time transactions, swaps, or liquidity changes.
Tools:
- Ethers.js: Interact with Ethereum smart contracts and filter events.
- Web3.js: Alternative library for contract interactions.
Example:
contract.on("Swap", (from, to, amount) => { console.log(`New swap: ${amount} tokens from ${from} to ${to}`); });
2. Liquidity Pool Analytics
Track:
- Total Value Locked (TVL) fluctuations.
- Pair-specific liquidity changes (e.g., ETH/USDC).
Platforms:
- Dune Analytics for customizable dashboards.
- DeFiLlama for cross-DEX comparisons.
3. Transaction History Parsing
Use Block Explorers:
- Etherscan API to query historical trades.
- The Graph for indexed blockchain data.

FAQ Section
❓ How do I set up real-time alerts for DEX trades?
→ Use tools like Ethers.js with WebSocket providers or third-party platforms like Tenderly.
❓ Which DEX platforms support API-based monitoring?
→ Uniswap, Sushiswap, and Curve offer public APIs; others require custom contract interactions.
❓ Can I track impermanent loss through these methods?
→ Yes, by monitoring liquidity pool ratios and price fluctuations programmatically.
