Query Vault is a repository built to help backends and indexers retrieve specific on-chain data efficiently through Cairo smart contracts. Instead of relying on event-based indexing, it uses on-chain get functions to access data directly, ensuring continuous and reliable data retrieval.
- Support for dApps: Enables batch retrieval of data when a user connects to the application.
- Indexer Replacement: Acts as a fallback solution in scenarios such as:
- The indexer is down.
- There are issues with event data.
- The indexer is undergoing a re-indexing phase.
By leveraging on-chain get functions, Query Vault avoids common pitfalls associated with event handling, offering a robust and scalable solution for developers working on decentralized applications and blockchain integrations.
