We have multiple testnet runtimes configured for the node. A new pallet I'm building is only available for testing in one testnet. There is also a new custom RPC I have written to call into the new pallet. How do I prevent errors caused by some of the runtimes not implementing the RPC interface because they don't have the new pallet included/configured when building the node?

I wonder if cargo features might help here, but not sure how to use it

you can just define some empty/dummy impl of the rpc interface, e.g beefy pallet is enabled in rococo but not yet in polkadot

or you can define particular rpc collections for each runtime

  • I guess I will go with the dummy impl approach for now. Thanks. But can you elaborate on how rpc collections approach would solve the problem?

  • just try dummy impl, with rpc collections approach much more effort
