Unified Schema

A Single API for Token Balances across 150+ Blockchains

No need to engineer around expensive RPC calls, missing tokens, and unsupported blockchains - time that can be better invested in enhancing your user experience.

Protect User Funds by Showing Approvals and Assets At Risk

Balances and Approvals go hand in hand. The approvals endpoints shows you assets at risk, categorized by spender creating a more secure and confident Web3 experience.

Native Name Resolution via ENS, RNS and Unstoppable Domains

Relying on 3rd party APIs results in inconsistent results, incomplete coverage and additional latency to your user experience. Every Class-A endpoint on Covalent resolves multiple name services, making for a user-friendly experience.


Historical Token Holders

Covalent has balances for each wallet on each block - building a snapshot of a token and its holders at a historic block is one call away.

Contract Metadata

Covalent has cached token logos and contract metadata for millions of tokens across chains. Developers don't have to integrate external APIs and add further latency to their queries.

Wallet Activity

Users have their assets and data scattered across dozens of blockchains. Covalent's Wallet Activity is a single API to show you what networks a user has assets on.
