I don't know smart contracts well enough, but this is probably a simple question for someone who does: can you make a contract that only allows an address to mint one NFT? i.e. I couldn't buy seven farcats, the contract would stop me at one

You mean limit one mint per address? That’s pretty common I think (unless I’m misunderstanding)

we did this so you couldn't buy more than 3 pieces of merch per wallet. don't believe it was very expensive https://github.com/gallery-so/contracts/blob/main/contracts/merch/MerchNFT.sol#L261-L266

Mint? Yes Buy/Transfer? ...Difficult. A wrapper contract around the NFT could be used to keep the illusion of each address having one NFT. This can be averted by limiting transfers only to EOAs & whitelisted smart wallets, though the latter will take up more time to identify & approve.

There have been many NFT projects that have had the 'n' mint/s per wallet rule. Some have even had 'n' free mints + 'm' paid mints. etc. This is definitely possible at the smart contract level & has been in practice for a while. Source: I'm a degen 😄

Of course! That's actually the default with the unlock protocol! One address can only own a single membership NFT!

You seem to understand the Sybil challenges, so why would you want to do this?

It is common. Even transfers could be "blocked" easily. Even There are no transferrable NFTs called SBTs (Soul Bound Tokens) The problem is that everyone is able to use a different wallet and break this rule. Own 2 in 2 diff wallets. There are some mechanisms like KYCs or biometrics auth to help with that, but..
