# Covalent (Analytics)

Covalent's GoldRush is a set of data tools that enable easy web3 development across 200+ blockchains.

The GoldRush API is RESTful and provides a unified approach to fetch blockchain data with a consistent request and response object format. For example, a developer can fetch all token balances for an address across any of the 200+ supported networks by changing the unique network name in the URL.
