Method 1: Configure on validator keys

Validator Clients

Teku

Assuming your Teku validator client is already set up, stop your Teku validator client.

sudo systemctl stop tekuvalidator.service

Find the pubkey values of your own non-CSM validator keystores generated.

sudo find /var/lib -name "keystore*.json"

For each resulting filepath, run:

grep -oP '"pubkey": *"\K[^"]+' RESULTING_FILEPATH

You should now have a list of all your own non-CSM validator keystore pubkeys.

Create a custom proposer configuration file.

sudo nano /var/lib/teku_validator/validator/proposer_configuration.json

Paste the following contents into the file.

{
  "proposer_config": {
    "YOUR_OWN_VALIDATOR_PUBKEY_(NOT_CSM)_01": {
      "fee_recipient": "YOUR_OWN_FEE_RECIPIENT_ADDRESS",
      "builder": {
        "enabled": true
      }
    },
    "YOUR_OWN_VALIDATOR_PUBKEY_(NOT_CSM)_02": {
      "fee_recipient": "YOUR_OWN_FEE_RECIPIENT_ADDRESS",
      "builder": {
        "enabled": true
      }
    },
    "YOUR_OWN_VALIDATOR_PUBKEY_(NOT_CSM)_03": {
      "fee_recipient": "YOUR_OWN_FEE_RECIPIENT_ADDRESS",
      "builder": {
        "enabled": true
      }
    }
  },
  "default_config": {
    "fee_recipient": "LIDO_EXECUTION_LAYER_REWARDS_VAULT",
    "builder": {
      "enabled": true
    }
  }
}

Replace YOUR_OWN_VALIDATOR_PUBKEY_(NOT_CSM) with your own actual validator pubkeys (NOT CSM).

Replace YOUR_OWN_FEE_RECIPIENT_ADDRESS with your desired wallet address.

Replace LIDO_EXECUTION_LAYER_REWARDS_VAULT with the following options.

• Mainnet

suggested_fee_recipient: "0x388C818CA8B9251b393131C08a736A67ccB19297"

• Hoodi

suggested_fee_recipient: "0x9b108015fe433F173696Af3Aa0CF7CDb3E104258"

CTRL+O, ENTER, CTRL+X to save and exit.

Set the permissions of the custom proposer configuration file.

sudo chown -R teku_validator:teku_validator /var/lib/teku_validator/validator

Adding more non-CSM validator keystores:

If you want to add more of your own validator keystores, replicate the following segment, taking note of the indentation.

    "YOUR_OWN_VALIDATOR_PUBKEY_(NOT_CSM)_03": {
      "fee_recipient": "YOUR_OWN_FEE_RECIPIENT_ADDRESS",
      "builder": {
        "enabled": true
      }
    }

CTRL+O, ENTER, CTRL+X to save and exit.

Edit the Teku validator client service file.

sudo nano /etc/systemd/system/tekuvalidator.service

Add the --validators-proposer-config flag and point it to the proposer_configuration.json file. Then remove the --validators-proposer-default-fee-recipient flag. e.g.,

[Unit]
Description=Teku Validator Client
Wants=network-online.target
After=network-online.target

[Service]
User=teku_validator
Group=teku_validator
Type=simple
Restart=always
RestartSec=5
Environment="JAVA_OPTS=-Xmx6g"
Environment="TEKU_OPTS=-XX:-HeapDumpOnOutOfMemoryError"
ExecStart=/usr/local/bin/teku/bin/teku vc \
  --network=hoodi \
  --data-path=/var/lib/teku_validator \
  --validator-keys=/var/lib/teku_validator/validator_keystores:/var/lib/teku_validator/keystore_password \
  --beacon-node-api-endpoint=http://<Internal_IP_address>:5051 \
  --validators-proposer-config=/var/lib/teku_validator/validator/proposer_configuration.json \
  --validators-builder-registration-default-enabled=true \
  --validators-graffiti="<your_graffiti_of_choice>" \
  --metrics-enabled=true \
  --metrics-port=8108 \
  --doppelganger-detection-enabled=true 

[Install]
WantedBy=multi-user.target

CTRL+O, ENTER, CTRL+X to save and exit.

Restart your Teku validator client.

sudo systemctl daemon-reload
sudo systemctl start tekuvalidator.service
sudo systemctl status tekuvalidator.service

Monitor for errors.

sudo journalctl -fu tekuvalidator -o cat | ccze -A

Nimbus

Configure a separate validator client and set the fee_recipient address to the Lido Execution Layer Rewards Vault there. Refer to the subpage below.

Method 2: Configure on separate validator client

Lodestar

The --proposerSettingsFile feature of Lodestar and its format is in alpha and subject to change. Hence we will fallback to running a separate validator client to customise the fee_recipient address.

Create a custom proposer_settings.yml file.

sudo nano /var/lib/lodestar_validator/proposer_settings.yml

Use the following template and make the necessary edits.

proposer_config:
  'YOUR_OWN_VALIDATOR_PUBKEY_(NOT_CSM)_01':
    graffiti: 'non-CSM graffiti'
    strict_fee_recipient_check: true
    fee_recipient: 'YOUR_OWN_FEE_RECIPIENT_ADDRESS'
    builder:
      enabled: true
      gas_limit: "30000000"
  'YOUR_OWN_VALIDATOR_PUBKEY_(NOT_CSM)_02':
    fee_recipient: 'YOUR_OWN_FEE_RECIPIENT_ADDRESS'
    builder:
      enabled: "true"
      gas_limit: "30000000"
default_config:
  graffiti: 'CSM graffiti'
  strict_fee_recipient_check: true
  fee_recipient: 'LIDO_EXECUTION_LAYER_REWARDS_VAULT'
  builder:
    enabled: true
    gas_limit: "30000000"
    selection: "maxprofit"
    boost_factor: "100"

Replace YOUR_OWN_VALIDATOR_PUBKEY_(NOT_CSM) with your own actual validator pubkeys (NOT CSM).

Replace YOUR_OWN_FEE_RECIPIENT_ADDRESS with your desired wallet address.

Replace LIDO_EXECUTION_LAYER_REWARDS_VAULT with the following options.

• Mainnet

suggested_fee_recipient: "0x388C818CA8B9251b393131C08a736A67ccB19297"

• Hoodi

suggested_fee_recipient: "0x9b108015fe433F173696Af3Aa0CF7CDb3E104258"

CTRL+O, ENTER, CTRL+X to save and exit.

Set the permissions of the custom proposer configuration file.

sudo chown -R lodestar_validator:lodestar_validator /var/lib/lodestar_validator

Adding more non-CSM validator keystores:

If you want to add more of your own validator keystores, replicate the following segment and place them under the proposer_config section, taking note of the indentation.

proposer_config:


    'YOUR_OWN_VALIDATOR_PUBKEY_(NOT_CSM)':
    fee_recipient: 'YOUR_OWN_FEE_RECIPIENT_ADDRESS'
    builder:
      enabled: "true"
      gas_limit: "30000000"

CTRL+O, ENTER, CTRL+X to save and exit.

Edit the docker-compose.yml file in the Lodestar folder.

cd ~/lodestar_validator
sudo nano docker-compose.yml

Add the --proposerSettingsFile flag and point it to the proposer_settings.yml file.

      - --proposerSettingsFile
      - /var/lib/lodestar_validator/proposer_settings.yml

Then remove the following flags.

      - --suggestedFeeRecipient
      - "<your_designated_ETH_wallet_address>"

New example:

services:
  validator_client:
    image: chainsafe/lodestar:latest
    container_name: lodestar_validator
    user: <UID>:<GID>
    restart: unless-stopped
    volumes:
      - /var/lib/lodestar_validator:/var/lib/lodestar_validator
    command:
      - validator
      - --dataDir
      - /var/lib/lodestar_validator
      - --importKeystores
      - /var/lib/lodestar_validator/validator_keystores
      - --importKeystoresPassword
      - /var/lib/lodestar_validator/keystore_password/<validator_signing_keystore_password_file_name>.txt
      - --network
      - hoodi
      - --beaconNodes
      - http://127.0.0.1:5052
      - --builder
      - --proposerSettingsFile
      - /var/lib/lodestar_validator/proposer_settings.yml
      - --doppelgangerProtection
      - --metrics
      - --metrics.port
      - "5064"
      - --graffiti
      - "your_graffiti_of_choice"
    environment:
      NODE_OPTIONS: --max-old-space-size=2048
    ports:
      - "5064:5064"

CTRL+O, ENTER, CTRL+X to save and exit.

Restart your Lodestar validator client.

docker compose down
docker compose up -d

Monitor for errors.

docker logs lodestar_validator -f

Method 2:

Alternatively, to configure a separate validator client and set the fee_recipient address to the Lido Execution Layer Rewards Vault there, refer to the following subpage.

Method 2: Configure on separate validator client

Lighthouse

Assuming you have set up your Lighthouse validator client and imported your CSM validator keystores. Stop your validator client.

sudo systemctl stop lighthousevalidator.service

Then, edit the validator_definitions.yml file with the designated fee_recipeint address.

sudo nano /var/lib/lighthouse_validator/validators/validator_definitions.yml
# Actual filepath might vary according to your configurations

Find the pubkeys of each of your CSM validator keystores.

sudo find /var/lib -name "keystore*.json"

For each resulting filepath, run:

grep -oP '"pubkey": *"\K[^"]+' RESULTING_FILEPATH

and add the following line under each keystore as a new line. Note: Take note of the exact indentation.

• Mainnet

suggested_fee_recipient: "0x388C818CA8B9251b393131C08a736A67ccB19297"

• Hoodi

suggested_fee_recipient: "0x9b108015fe433F173696Af3Aa0CF7CDb3E104258"

Automation Tools

ETH Docker

With ETH Docker running (i.e., ethd up), run

./ethd keys list

then

./ethd keys set-recipient 0xPUBKEY 0xADDRESS 

with the public key of the key you wish to set a separate fee recipient for, and the Ethereum address fees should go to.

ETH Pillar

Not straightforward. Designed to assign custom fee_recipient addresses by running a separate validator client. Refer to the subpage below, under "Automation Tools"
