Subsquid

Subsquid is a blockchain indexing SDK that features specialized data lakes, known as Archives, designed to efficiently extract large amounts of historical on-chain data. The SDK provides a highly adaptable Extract-Transform-Load-Query framework, boasting indexing speeds that can exceed 50,000 blocks per second for events and transactions.

To illustrate its capabilities, Subsquid can index all 10,000 events within 4 million blocks of Uniswap V3 Factory contract history in approximately 8 minutes. For a more demanding Uniswap V3 Positions NFT contract, which consists of 3.1 million events and function calls, the indexing process takes around 40 minutes.
