    AGGREGATOR = "aggregator"
    // SEQUENCER is the sequencer component identifier
    SEQUENCER = "sequencer"
    // RPC is the RPC component identifier
    RPC = "rpc"
    // SYNCHRONIZER is the synchronizer component identifier
    SYNCHRONIZER = "synchronizer"
    // ETHTXMANAGER is the service that manages the tx sent to L1
    ETHTXMANAGER = "eth-tx-manager"
    // L2GASPRICER is the l2 gas pricer component identifier
    L2GASPRICER = "l2-gas-pricer"
    // SEQUENCE_SENDER is the sequence sender component identifier
