# Chainscout Chains List

> Chainscout is a JSON-based directory of EVM networks running Blockscout, including chain IDs and metadata contributed via pull requests.

<Info>
  Chainscout is currently in Beta. Visit a live instance at [https://chains.blockscout.com/](https://chains.blockscout.com/)
</Info>

* Chainscout includes chain IDs and other chain information formatted as a JSON file. Add your own chain details through a pull request.
* Visit the repository to learn more: [https://github.com/blockscout/chainscout](https://github.com/blockscout/chainscout)
* Once all chains have been added, Chainscout will replace the current Blockscout chains and projects page located at [https://www.blockscout.com/chains-and-projects](https://www.blockscout.com/chains-and-projects).

## Find a chain ID

Chain IDs are standard EVM network identifiers. The same value is used in wallet configuration and in the `chain_id` parameter of the [PRO API](/devs/pro-api).

1. Open [chains.blockscout.com](https://chains.blockscout.com/) and search by chain name.
2. The chain's entry shows its chain ID and the URL of its hosted explorer instance.

Common examples:

| Chain            | Chain ID |
| ---------------- | -------- |
| Ethereum Mainnet | `1`      |
| OP Mainnet       | `10`     |
| BNB Smart Chain  | `56`     |
| Robinhood Chain  | `4663`   |
| Base             | `8453`   |
| Scroll           | `534352` |

Chainscout lists every chain running Blockscout. To confirm a chain is queryable through the PRO API, check the supported chains list on the [PRO API page](/devs/pro-api) or at [dev.blockscout.com](https://dev.blockscout.com).
