. is their any way to call the read methods using this api? and what should be contract call data for read method in my case it doesn’t any parameters to be passed

here is abi for the contract :  
[{“inputs”:[{“internalType”:“uint256”,“name”:“a”,“type”:“uint256”},{“internalType”:“uint256”,“name”:“b”,“type”:“uint256”}],“name”:“add”,“outputs”:,“stateMutability”:“nonpayable”,“type”:“function”},{“inputs”:,“name”:“getResult”,“outputs”:[{“internalType”:“uint256”,“name”:“”,“type”:“uint256”}],“stateMutability”:“view”,“type”:“function”}]

Hey @SvvrCg,

We currently don’t support read calls via Fireblocks API. To do so you’ll need to use an external RPC provider.

Hello, is this the case? No way to call a read method on a deployed contract?  
Please can you provide an example of how to do this C# and external RPC provider  
Thank you
