I'm trying to call an Exchange SmartContract which is POORLY designed/implemented and forces you to sign your own parameters instead of using msg.sender (and provides no alternative). <-- I've just seen its not poorly designed, they limit the contract to themselves... weird
I'm calling this Exchange from my own SmartContract.
Someone could tell me a way (if possible) to tell my SmartContract to sign some parameters? I can't sign from outside, because I don't have my SmartContract private key.
-Lets say I have "uint one, uint two, address three" and I want to get the "r,v,s" of those three parameters signed with my Smart Contract address (all this done using Solidity).
