Hello 
I was working on a kindred EIP (Idea: ERC for redeem codes - #2 by dohzya) but it seems like you were too fast (or I was way too slow 
).
My proposal is focused on securing the redeeming part: how to allow your target user to redeem the token while avoiding anyone else to redeem it. I don’t understand how to do that on a EIP-5560 contract.
To make a redeeming secure with a EIP-5560 contract, do I have to pre-assign the token to the right account?
To be honest, I’m trying to understand if we are working on the same thing (if yes I will try to adapt my code to use this EIP) or if we have distinct goals (if so, maybe we both should use a less ambiguous name 
)
