Operator FAQ

The EigenLayer Operator installation guide is available here.

How do I get whitelisted to run an operator?

To get whitelisted, you need to fill out the form available here 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.

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

• Blast

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.

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.

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.

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:

  curl https://mainnet.telemetry.alignedlayer.com/versions/<operator_address>

• Sepolia:

  curl https://sepolia.telemetry.alignedlayer.com/versions/<operator_address>

• Hoodi:

  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

• Sepolia Operators Explorer

• Hoodi Operators Explorer

How do I check the operator version locally?

To see the operator version, run:

./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:

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

• Sepolia:

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

• Hoodi:

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

Note: You need to have installed Foundry

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