Through this article, we have realized the Web3 Tron package based on the FMZ Quant platform, and connected to SunSwap DEX successfully, completing the complete process from querying the trading pool to executing the exchange and parsing the transaction results. This not only provides an efficient automation solution for DEX transactions in the Tron ecosystem, but also demonstrates the powerful scalability of the FMZ Quant platform.

I hope that the practical experience in this article can provide valuable reference for your quantitative trading system. Next, I will study the DEX on SOL. Thank you for reading~
