In the context of blockchain and dApps, indexers go beyond traditional databases, facilitating streamlined access to on-chain data. This includes transaction histories, smart contract states, and event logs. In the dynamic and decentralised world of blockchain, indexers contribute to the efficiency of data queries, supporting real-time updates and ensuring the seamless functionality of diverse applications and platforms.

There are several indexer solutions available, each offering different levels of decentralisation, ease of development, and performance for you to consider. These solutions serve as intermediaries to assist in indexing the UX network.


SubQuery is a leading blockchain data indexer that provides developers with fast, flexible, universal, open source and decentralised APIs for web3 projects. SubQuery SDK allows developers to get rich indexed data and build intuitive and immersive decentralised applications in a faster and more efficient way. SubQuery supports 100+ ecosystems including UX, Cosmos, Ethereum, Polygon, Polkadot, Algorand, NEAR, and Avalanche.

Another one of SubQuery's competitive advantages is the ability to aggregate data not only within a chain but across multiple blockchains all within a single project. This allows the creation of feature-rich dashboard analytics, multi-chain block scanners, or projects that index IBC transactions across zones.

Other advantages include superior performance with multiple RPC endpoint configurations, multi-worker capabilities and a configurable caching architecture. To find out more, visit our documentationopen in new window.
