[$1000 in SQT] Query chain state at the current height

[stwiname]

It is not always practical or possible to get all the information required from handlers and the only way to get that information is by querying the contract state. Subql-cosmos allows querying contract state through the injected client but this will return the current state and not the state at the height being indexed.

This feature should inject a client to the sandbox that limits querying state to the current height being indexed.

Other requirements

• Documentation should be updated to include the feature
• Tests with examples that query the correct data at a specific height

Here is an example of querying wasm state at a specific height:

So this is for Cosmos?
Shouldn't be that hard with their contract API...
I worked on Mars protocol recently, may be able to come up with a solution

@jilt that is correct, we'd appreciate some pointers here if you know exactly how to do it.

@jamesbayly Hi. I'd like to give this a shot. Is the bounty still valid?
