I want to connect Blynk to ESP32 via Ethernet, do we have any library to do this?
yes. the ESP32 WiFi library can work with LAN8720 or TLK110. see the examples of the WiFi library

[/quote]Can you give me a sample example? I looked and didn’t find it
see examples of the esp32 Arduino WiFi library
Wifi libraries for ESP32 mostly talk about Wifi, don’t see any mention of Ethernet
so it is called WiFi because of the original use, but the TCP stack has defined layers and the lower layers can be switched between different interfaces. see the ETH examples of the esp32 WiFi library
