### Envs
Please make sure that these variables are set correctly (creds for Kafka are the same as before):
```env
RPC_URL=<mainnet RPC url>
KAFKA_USERNAME=<username>
KAFKA_PASSWORD=<password>
KAFKA_BROKER_ADDRESS_1=pkc-l7q2j.europe-north1.gcp.confluent.cloud:9092
WALLET_PRIVATE_KEY
```
The other ENV variables do not need to be changed, they should have default values:
```env
PORT=3000
LOG_LEVEL=debug
LOG_FORMAT=json
PUBSUB_SERVICE=kafka
KAFKA_TOPIC=defender
KAFKA_SASL_MECHANISM=plain
KAFKA_SSL=true
```
The new version will reset the cache, the start will take more than 30 minutes.
