Is there a Filecoin test network and test coins used?

Filecoin transfer test address and faucet?

Hi @hekang, and welcome to the Infura community! You can learn more about Filecoin and its networks here in their docs, and you should be able to get FIL from this faucet.

How to get test url?@Leiya_Kenney

Hi @hekang, from the link in my previous post, Calibration is the primary live testing network

@Leiya_Kenney What I want to ask is the rpc address of Calibration.

Where can I find the rpc address of Calibration?

You can build on Lotus - instructions for this can be found in the Filecoin docs.
