A real explorer would query a factory contract to discover all pairs dynamically. Step 4: Making It Useful – Real-Time Monitoring A script that runs once is a toy. A script that runs forever is a tool.

If you’ve ever wanted to peek under the hood of a decentralized exchange (DEX) like Uniswap or PancakeSwap, you’ve probably realized that while the data is public , it’s not exactly easy to read.
