Despite all the progress we’ve made in crypto tooling the last couple of years, one difficult task remains unsolved: extracting data from blockchains. Blockchain data is messy, disorganized and time-consuming even for an experienced engineer. Today, we are excited to announce a software development kit (SDK) to query data from the Ethereum blockchain – a problem we’ve been trying to solve for many years. We’ve been dogfooding the SDK internally for the last few months and used it to instrument over 20 DeFi protocols supporting over a dozen customers and thousands of users.
