A contract serves as a proof of promise, having someone agree to a trade of any sorts is a contract, even when verbal. The issue is that there is no way to verify that the contract wasn’t forged or tempered with, which is why an unaffiliated third party must observe the promise being made in real time and record it on their own.
This serves as a two-step verification process that, while not foolproof , is much more reliable than a random screenshot.
Now, if it wasn’t obvious enough, the unaffiliated third party that must be free of bias under all purpose in this context is you, @anon904914.
You are the one that has a say in the reward’s transaction, meaning that you are the one which must be informed of such promises.
ill share but half the key that I have so far is literally “To Pandora’s Box” which gives like half of the answer, I just need to find the rest I think
