SQD is a full-stack blockchain indexing SDK and specialized data lakes optimized for extraction of large volumes of historical onchain data. The Squid SDK offers a customizable Extract-Transform-Load-Query stack for building custom GraphQL APIs and ETLs for advanced blockchain use cases.
SQD provides access to a specialized data lake designed for onchain data and optimized for batch data access. The data lake is meant to be used as a data source for Squid SDK processors. Compared to data access using a conventional chain node RPC, it allows one to access data in a more granular fashion and from multiple blocks at once, thanks to its rich batching and filtering capabilities.
