Thanks to the use of blockchain explorer or by recovering it from the smart contracts that manage them, it is possible to find the metadata of an NFT . Basically, metadata is data that provides information about more data. In the case of an NFT, we will obtain information about its fundamental properties: name, description and anything that its creator will consider important..
Sometimes the metadata of an NFT has links to different images and other digital assets that provide value to this non-fungible token.
NFTs are not usually divided into smaller parts. Instead, structured metadata related to real or virtual things is represented by NFTs. In some cases, tokens are not connected to objects and function as distinct identifiers, enhancing interoperable merchandising of physical or digital items..
Find the metadata of any NFT
Once an NFT project is available for minting and we acquire it, a random number generator will provide our NFT with a set of features. It is the metadata that has this information. The blockchain has an immutable record of token information. In this record we will find information about the idea of the token, who the owner is and the past transactional activity.
Therefore, we can see the metadata, confirm its ownership and it is even feasible to track the transaction history thanks to a non-fungible token tracking and verification service with which we can verify that the token ID and contract address are really connected to the real owner using a market database..
Etherscan, an Ethereum blockchain explorer, is an extremely popular tool for locating and confirming NFTs. It provides the ability for its users to view transaction history, addresses, metadata, smart contracts, and various other on-chain data. In a similar way, we can find all NFT metadata on the BNB chain network using BscScan.
But in order to find the metadata of an NFT from the smart contracts that control it, we are going to have to access it. The metadata must be accessible for inspection and verification in the “Details” section of the contract. In case the NFT meets current standards, it should show this:
ash-nft.json{
«description»: «OpenSea friendly creature»,
«image»: «https://opensea-prod.appspot.com/puffs/3.png»,
"name": "Dave Starbelly",
» attributes»: [
{ «trait_type»: «Base», «value»: «Starfish» },
{ «trait_type»: «Eyes», «value»: «Large» },
{ «trait_type»: «Mouth», «value»: «Surprised» },
]
}
NFTs can be linked to data outside of their smart contract, this allows the network to refer to data off-chain. The result is simple, running NFTs on a network like Ethereum has lower compute overheads than they would otherwise be.
But the asset itself is often kept off-chain, while the NFT that defines the origin of an asset is on the blockchain. However, there are some exceptions; We find the famous OnChain Monkeys collection, which was developed completely on chain in a single transaction. Since the collection is hosted on-chain, there is no need for a file storage solution.
