Alright, this week imma keep it commin: Now you can make the editor interact with contracts that are already existing on chain! You need to have both the correct code (pasted in the editor) and address, and there you go:
Caution: Currently, the SDK does not check whether the address you provided “makes sense” (e.g. is there a contract / the contract you expect?), it does only so if you actually call some function. I Created an issue on this. The check also requires the code having been compiled with the same compiler version I think, but if the issue is being handled the way I suggested this shouldn’t be a big deal anymore.
