Subsquid

Subsquid is an API framework that supercharges the development of multichain dApps and analytics dashboards. With a modular architecture and dozens of networks and parachains supported, we offer the best possible backend for applications in DotSama.

Subsquid takes a multi-layered approach that separates raw data ingestion from data processing and presentation.

This is very useful for the vast majority of developers, as it adds a layer of abstraction, taking care of data ingestion and synchronization, and exposing decoded Substrate chain entities (Events and Extrinsics, as well as entire Blocks), for developers to process.
