    - update `AGGREGATOR` if needed - Contract address of aggregator instance.
    - update `CONFIRMATIONS` if needed - how many block confirmations to wait before processing an event. Not recommended to set less than 3
    - update `MAX_GAS_PRICE` if needed - maximum value of gwei value for relayer's transaction
+   - update `BASE_FEE_RESERVE_PERCENTAGE` if needed - how much in % will the network baseFee increase
 
      If you want to use more than 1 eth address for relaying transactions, please add as many `workers` as you want. For example, you can comment out `worker2` in docker-compose.yml file, but please use a different `PRIVATE_KEY` for each worker.
