The tools that accentuate and aggregate the data within blockchains are integral for a multi-chain future. Parachains will need robust and secure ways to index and aggregate data, such as a data aggregation layer.
is an open-source framework for building tailored GraphQL APIs to query Substrate chain state and history.
Subsquid replaces direct gRPC node access with perfomant Squid archive gateways, allowing quick synchronization of the API with the historical on-chain data.
Subsquid-powered APIs support filtering, pagination, union types, interfaces and full-text search out-of-the-box, and can be further extended with custom GraphQL resolvers.
is an indexer that allows for the indexing, transforming, and querying of Substrate chain data to power applications. The decentralized network acts as a chain-agnostic data aggregation, indexing, and querying layer between blockchains and applications.
SubQuery abstracts away blockchain-specific data idiosyncrasies using the .
is a Polkadot-based open data analytics platform that provides infrastructure and tooling to help users visualize, curate, share, and analyze on-chain data.
is a layer-1 indexing tool and querying layer for the decentralized web, who announced an integration plan to bring .
The Graph allows developers to build and publish open APIs, called subgraphs. Applications can query subgraphs using .
Covalent captures the entire history of blockchains and offers a way to zoom into data points recorded in smart contracts that are often not accessible.
As you can imagine, blockchain explorers also offer data analytics through an interface where users can examine common data points.
offers a unified API to understand the data on a blockchain, and is currently live on the network, bringing visibility to billions of blockchain data points to Polkadot via their unified API. The approach to deploy on Moonbeam simplifies the development of Polkadot-based blockchain applications as compared to implementing a full parachain or parathread.
Some block explorers in the Polkadot ecosystem are listed on the .
