One of the unique benefits of NFTs is the ability to track every transaction on the blockchain. Every NFT has an owner, creator, history, and this information or "provenance" is verifiable on-chain.
On each item’s page there is a section marked Details where you can verify details about the contract used to create it.
Clicking in will reveal important information about the NFT, such as:
- Contract address of the collection.
- Token ID of this particular NFT.
- Blockchain the NFT resides on, eg: Ethereum, Polygon/Matic, Klatyn.
- Whether the NFT metadata is centralized or "frozen".
