What you're literally buying is just a uint256 number + the address of the minting wallet, not even a URL or link. The URL comes from feeding that number into a function of the smart contract, but you don't "own" that smart contract. You just "own" the number. See the spec as it were: https://eips.ethereum.org/EIPS/eip-721 https://eips.ethereum.org/EIPS/eip-721 > The pair (contract address, uint256 tokenId) will then be a globally unique and fully-qualified identifier for a specific asset on an Ethereum chain. And while the code of that smart contract is immutable, it's still code and the outputs of any given function can change even when given the same inputs. The code can of course poison itself by observing other state or even delegating to other contracts, allowing forms of mutability of the contract itself. Which, reminder, you don't own in an NFT. So hope you really really like the uint256 you bought. Also hope you have a good grasp of solidarity & really did an analysis of that smart contract first. That's a totally reasonable thing to expect people to do, right?
