Exit validator instance / validator(s)

A validator can be exited with following command: 
lighthouse --network "$chain" account validator exit --keystore /path/to/keystore --password-file "$HOME/exit/keystore-password.txt" --beacon-node http://localhost:5052
Where:
  • --network is mainnet for Ethereum chain and gnosis for Gnosis chain
  • --keystore is a path to the keystore file of specific validator
  • --password-file is a file with exit passowrd placed in
  • --beacon-node is a beaconnode url

Example request can look as below:

/usr/local/bin/lighthouse --network mainnet account validator exit --keystore /var/lib/lighthouse/vi1/validators/keystore... --beacon-node http://localhost:5052
/usr/local/bin/lighthouse --network gnosis account validator exit --keystore /var/lib/lighthouse/vi1/validators/keystore... --beacon-node http://localhost:5052

For confirmation, place exit phrase Exit my validator

    /usr/local/bin/lighthouse_exit_validators.sh mainnet /var/lib/ethereum/lighthouse/vi1/validators http://localhost:5052
    /usr/local/bin/lighthouse_exit_validators.sh gnosis /var/lib/gnosis/lighthouse/vi1/validators http://localhost:5052
    • Replace /var/lib/gnosis/lighthouse/vi1/validators/ for a path to your instance keystores
    • Run the script
    • On Confirm exit request for listed validators? (y/n):, press y to confirm the exit request
