# Operator FAQ

The EigenLayer Operator installation guide is available [here](https://docs.eigencloud.xyz/products/eigenlayer/operators/howto/operator-installation).

### How do I get whitelisted to run an operator?

To get whitelisted, you need to fill out the form available [here](https://docs.google.com/forms/d/e/1FAIpQLSdH9sgfTz4v33lAvwj6BvYJGAeIshQia3FXz36PFfF-WQAWEQ/viewform) and wait for the Aligned team to approve your request.

### What Strategies Tokens are supported in Mainnet?

The list of supported strategies can be found [here](https://github.com/yetanotherco/aligned_layer/blob/testnet/docs/3_guides/7_contract_addresses.md).

### What RPC should I use?

We suggest you use your own nodes for better performance and reliability. Note that the node must support HTTP and WebSockets.

We also recommend the following RPC providers:

* [Infura](https://infura.io/)
* [Blast](https://blastapi.io/)

Two RPCs are used, one as the main one, and the other one as a fallback in case one node is working unreliably.

Default configurations is set up to use the same public node in both scenarios.

{% hint style="danger" %}
PUBLIC NODES SHOULDN'T BE USED AS THE MAIN RPC. We recommend not using public nodes at all.

FALLBACK AND MAIN RPCs SHOULD BE DIFFERENT.
{% endhint %}

Most of the actions will pass through the main RPC unless there is a problem with it. Events are fetched from both nodes.

### How can I check if the version I'm using is the latest one?

You can check the latest version available on the [releases' page](https://github.com/yetanotherco/aligned_layer/releases).

### How do I check the operator version registered on the Aligned version tracking system?

You can get the registered version of your operator by running the following command:

* Mainnet:

  ```bash
  curl https://mainnet.telemetry.alignedlayer.com/versions/<operator_address>
  ```
* Sepolia:

  ```bash
  curl https://sepolia.telemetry.alignedlayer.com/versions/<operator_address>
  ```
* Hoodi:

  ```bash
  curl https://hoodi.telemetry.alignedlayer.com/versions/<operator_address>
  ```

Replace `<operator_address>` with your operator address.

Also, you can check the operator version in the Explorer:

* [Mainnet Operators Explorer](https://explorer.alignedlayer.com/operators)
* [Sepolia Operators Explorer](https://sepolia.explorer.alignedlayer.com/operators)
* [Hoodi Operators Explorer](https://hoodi.explorer.alignedlayer.com/operators)

### How do I check the operator version locally?

To see the operator version, run:

```bash
./operator/build/aligned-operator --version
```

You have to be in the root `aligned-layer` directory to run this command.

This will show the version of the operator you have built in your filesystem.

### How do I get the ID of the operator?

You can get the ID of the operator by running the following command:

* Mainnet:

  ```bash
  cast call \
      --rpc-url https://ethereum-rpc.publicnode.com \
      0x3CcfB7e6e8fe2A8d941a8Ce4C69A944a770E8228 \
      "getOperatorId(address operator)(bytes32)" <operator_address>
  ```
* Sepolia:

  ```bash
  cast call \
      --rpc-url https://ethereum-sepolia-rpc.publicnode.com \
      0x0Ef1920F089DD02d3A28BF2e34342FD3e74160A3 \
      "getOperatorId(address operator)(bytes32)" <operator_address>
  ```
* Hoodi:

  ```bash
  cast call \
      --rpc-url https://ethereum-hoodi-rpc.publicnode.com \
      0xD06AAf23d136ECBfb5Bdb349Dd7a87aDc74673Dd \
      "getOperatorId(address operator)(bytes32)" <operator_address>
  ```

> Note: You need to have installed [Foundry](https://book.getfoundry.sh/)

This will return the operator ID if the operator is registered, otherwise it will return `0x`.
