Covalent is a hosted blockchain data solution providing access to historical and current on-chain data on Cronos and other blockchains.

Covalent maintains a full archival copy of every supported blockchain, meaning every balance, transaction, log event, and NFT asset data is available from the genesis block. This data is available via:

  1. Unified API - Incorporate blockchain data into your app with a familiar REST API

  2. Increment - Create and embed custom charts with no-code analytics

Consider using Covalent if you need:

  • Structured and enhanced on-chain data well beyond what you get from RPC providers

  • Broad and deep multi-chain data at scale

  • Enterprise-grade performance
