I also want to know that some of the ones I found are old versions

This is not yet possible unfortunately.
We are working on a solution called "chain extensions" that will allow runtimes to customize the contracts API in order to further allow calling into the runtime if the runtime chooses to provided this functionality.
However, implementation on the Substrate side is not yet done.

Parity is a cross chain ecology, but the biosphere is a prison. I'm so sad @Robbepop @athei

The chain-extension feature is well on the top of our priority list to work on. Hopefully won't take too long to get it done.

Is Call contract from runtime the same case as this one and can be supported by the chain-extension feature?

[athei]

Yes. Chain extensions is the means to call custom functions in your runtime.

Chain extensions have just been implemented in #592.
Closed.
