Here I added the Cronos smart contract example, and I want to test it on the staging environment.
Can you guys check it?

Thank you for your contribution! It seems this CDS file is for ERC-20 token contract, is that correct? We already have a CDS file for that, it is usable on all supported chains and we don't need to create a new CDS file for Cronos, after we add support for Cronos in our driver we can just use that.

Thanks for your reply. I now understand more about this product. The thing I will do for integrating Cronos is create new a new driver (connector) for Cronos, is that right?

We don't need to add an entirely new connector/driver, since Cronos is an EVM chain we just need to modify the existing web3 driver to support it. Specifically, just add API endpoint for Cronos, modify some code to support non-ANKR API, and then update the UI to enable it.
