An NFT collection is simply a related grouping of NFTs, which may or may not have been minted together. In the world of NFTs, "Contract" and "Collection" are terms that distinguish two types of groupings. An NFT contract, especially on EVM-based chains, is an on-chain smart contract that issues NFTs and has a unique address. This address and the token ID identify any NFT under standards like ERC-721 or 1155.

Collections, conversely, on EVM chains are mostly off-chain entities tied to specific marketplaces. For instance, Moonbirds on OpenSea has a unique identifier for its collection. While contracts often match collections one-to-one, there are exceptions. OpenSea's storefront contract, for instance, encompasses numerous individual collections. Other non-EVM chains have different approaches for collections (e.g., the Metaplex standard is popular on Solana). Given these complexities, SimpleHash offers a unique identifier for each collection. Using the SimpleHash API, you can effortlessly discern contract and collection data for any NFT.
