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. return swaps latest = w3

for s in swaps[:5]: print(f"Swap by s['sender']: s['amount0_out'] tokens out") Hardcoding a single pair address is fine for testing. 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.
