Quick question - if I have an ERC1155 that only does transfers, is there a way to modify the contract to make things sellable?

Why wouldn't it be sellable this way?

The contract that sells the erc1155 receives whatever is the asset needed to buy and transfers the erc1155

It was a POAP. The initial constructor only has a transfer from function. Could that be the problem?

If it is a POAP then it is not meant to be sold/transferred

It's like if I try to transfer my degree as an nft, that's not supposed to happen

That thing is used to certify that something that is about the address that receives it

Ohhh. So, there’s no way for it to be minted?

All answers are in the code, but if you tell me that's a POAP then I expect it to be impossible to be transferred

Or to require a trusted centralized party to authorize the transfer

So if for example my degree was issued as an nft and then I want to move it to another address I'd have to contact the university and provide proof that I control both the addresses to put them in a position to authorize the transfer

So the POAP would need proof first before a transfer could happen?

So what would be the best way to transfer it? Airdrop? Could an airdrop work for a POAP?

Ideally that's the concept

POAPs are not meant to be exhanged

Gotcha. I need to clarify what the client is actually looking for then. Could I pop back in here if I have further questions?
