Event Listening from Aurora Testnet

1

Hi,

When I try to listen events from aurora testnet I get below error… This my WS url, wss://aurora-testnet.infura.io/ws/v3/. Can someone please tell me how to fix this. I may provide the eventlistener coe if requested. It is a basic, straightforward approach.

Hi @ferdaozdemirsonmez, please note that websockets are not supported for Aurora. Currently wss is supported just for Ethereum mainnet, Goerli and Sepolia.

Hi,
Thanks for the response. I will try Goerli now. I also couldn’t listen events on Hardhat and Ganache. I tried different event listener codes, subscription and the on method. Do you know which two chains (preferably test or local) are best to test a scenario where I will be listening events deployed to two different chains via typescript code?

I have been trying this simple event listener for different chains for the last 15 days. I am thinking I might not be the only person who as to listen events so at some chains this should work. Please help…

Any input is greatly appreciated.
Have a great day.
Ferda
