NFT Indexers
What is Indexer
An NFT indexer is a tool that reads, processes, and organizes blockchain data, making NFT metadata, ownership, and transaction history easily accessible for applications without directly scanning the blockchain.
Applications
- dApps & Marketplaces – Need fast and structured access to NFT data for seamless user experiences.
- Wallet Interfaces & Block Explorers – Require standardized metadata retrieval to display NFTs properly.
- Analytics Platforms – Depend on reliable transaction history and ownership tracking.
- Developers – Need indexing APIs to avoid manually querying blockchain data.
