Hi, you can already test it now, we went live with it, we have to do some more tests.

Chain id: 0x14a34

Update: we released web3api today. I’ll have to check streams api.
Update: streams api should work also, the UI is not ready yet, but you could use the API or swagger interface.


Thanks! I can confirm that it works!

Hi, @cryptokid! Is there a way to test a stream on Base Sepolia other than going through the UI? Thanks!

Hi @gabrielstoica

You can use the API endpoints directly to use the Base Sepolia chain. Please have a look at the below swagger docs for the stream endpoint details.

Feel free to reply if you have any questions.
