Call payment runtime API directly instead of using custom RPC

[xlc]

As we are deprecating custom RPC in favour of runtime API, we should avoid transaction payment RPC and use the runtime API directly.

api/packages/api/src/submittable/createClass.ts

Line 143 in 0473b03

api.callAt(blockHash || optionsOrHash as string).pipe(

Helps with paritytech/substrate#12633 as there is no more RPC to deal with and support of new runtime API can be done purely on client side without the requirement of updating Substrate node & upgrading all deployments from multiple node providers.

The above linked/code sample uses state_call via api.call already. So missing the specific request here.

(Apps UI is the same - it uses the api.call interfaces without custom RPCs for paymentInfo.

Same applies to both the API and UI for other areas, eg. Contracts - if there is a state call, it is used instead of the old-generation RPCs.

Where state_call interfaces are available, the RPC itself on the API is also marked deprecated on the RPC with the name of the runtime calls)

Right. I misread the code.
