Dear Zhuojia I've experienced similar project before with PHP (laravel) If you want to get information from blockchain itself like ethereum, I will use REST api or GraphQL (websocket also can be used). If you want to get information from exchange, I will use CCXT library. But the principle is same in case of JavaScript. I hope to discuss the details via direct message. Regards
