How to setup a connection to a chain without gRPC enabled

Problem

This is a question, not really a bug.

• grpc_addr is required in chain config
• Some cosmos chain does not enable gRPC in their node, e.g. Akash Testnet-3

How can I set up Hermes to connect to it?

Hi,

In general, we don't support a "restricted" mode that can do without gRPC connectivity.

But it depends on your use-case. What would you like to achieve exactly? If you're looking to simply do some queries about the IBC state of Akash Testnet-3 (e.g., query a client state might work without gRPC), then you can try to set grpc_addr to some incorrect address and its possible Hermes will work, though note we never tested this scenario. If you want to do any more advance query or submit transactions to/from Akash Testnet-3, then gRPC is necessary.

Thanks,

I got a transport error for setting it to some random value.
I'm creating an IBC channel and may submit transactions, so seems grpc is mandatory here.
I will try to address this on Akash's side then.
