# Covalent

## Introduction

[Covalent](https://www.covalenthq.com/?utm_source=fantom\&utm_medium=partner-docs) is a hosted blockchain data solution providing access to historical and current on-chain data for 100+ supported blockchains, including [Opera](https://goldrush.dev/docs/networks/fantom/).

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](#unified-api) — Incorporate blockchain data into your dApp with a familiar REST API
2. [Increment](#increment) — Create and embed custom charts with no-code analytics

Use 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

## Increment

[![example-increment-chart](https://www.datocms-assets.com/86369/1684974544-increment-example-partner-docs.png)](https://www.covalenthq.com/platform/increment/#/?utm_source=fantom\&utm_medium=partner-docs)

Increment is a novel no-code charting and reporting tool powered by Covalent, revolutionizing how the Web3 space approaches analytics. Many analytics tools let you write SQL to create charts, but *Increment is the only one to encode business logic - Reach, Retention, and Revenue - into an SQL compiler that can write valid SQL for you.*

### **Use Cases**

Increment can be used for:

* [Analyzing Blockchain Networks](https://www.covalenthq.com/docs/increment/data-models/chain-gdp/?utm_source=fantom\&utm_medium=partner-docs)
* [Analyzing DEXs](https://www.covalenthq.com/docs/increment/data-models/swap-land/?utm_source=fantom\&utm_medium=partner-docs)
* [Analyzing NFT Marketplaces](https://www.covalenthq.com/docs/increment/data-models/jpeg-analysis/?utm_source=fantom\&utm_medium=partner-docs)

For example, click on the following table to get the latest number of active wallets, transactions, and tokens by day, week, month, or year for Fantom: \
