# Block Explorers

***

The [Validium Block Explorer](https://testnet.explorer.validium.network) details comprehensive data about transactions, blocks, batches, wallets, tokens, and smart contracts on the Validium network.

## Block Explorer API

We’ve developed the Validium Block Explorer API for developers to access Validium Block Explorer data directly via HTTP requests.

* [Mainnet Block Explorer API](https://block-explorer-api.mainnet.zksync.io/docs)
* [Testnet Block Explorer API](https://block-explorer-api.sepolia.zksync.dev/docs)

The API provides various endpoints for many use cases you might want in your app. It is compatible with [Etherscan API](https://docs.etherscan.io/), which makes it easy to transition your existing apps to Validium network.

Feel free to contribute and create issues and feature requests in [Validium Chain Block Explorer GitHub repo](https://github.com/Validium-Chain/validium-block-explorer).
