How to determine the reliability of NFT #ZKSwap V3 #NFT

A couple of months ago, I decided to use a service to check the reliability of NFT. I have tested it and it does not work well so far.

For example, for many tokens normally implemented according to the 721st standard, it cannot determine the URI of the metadata at all, although the tokenURI () function in the contract of these tokens works fine.

Therefore, I would advise you to study the information on each project yourself, google, contact the developers on twitter or discord, or study the smart contract on Etherscan.

This is a small overview of ways to store metadata and media for the most popular NFT platforms.


Metadata and media are stored on the blockchain


Hash for metadata and for media - IPFS.


Metadata is on the blockchain.

Metadata: The collection name and artist name are stored on the blockchain. Some job titles are on the blockchain, some off-chain.


LazyMinting technology makes it difficult to uniquely hash a resource. Metadata and art are stored in the project’s own repository.

It is my hope that ZKSwap implements all of the NFT authentication tools on one platform.
