@attestate/crawler

A JavaScript library for retrieving on-chain storage and generating data derivatives.

Modular: Extract, Transform and Load stage separation makes composing simple components into complex workflows possible. Stages are reunnable to recover errors.
Embedded: Unlike Graph Protocol, Attestate's Crawler does not have a separate server process. It writes directly to LMDB, an embedded database that can be read-from thread-safely at any time.
Batteries-included: Support for Ethereum, IPFS, Arweave, GraphQL and rate-limit pooling for Infura and Alchemy.
