Note

Right now the change is in the testing phase.

Testing

Tested with latest mezod v1.0.0-rc0 binary.

testnet

Command:

/var/mezod/bin/mezod-v1.0.0-rc0/mezod ethereum-sidecar --log_format=json --ethereum-sidecar.server.ethereum-node-address="<redacted>" --ethereum-sidecar.server.network="sepolia"

Output:

{"level":"info","module":"server","module":"ethereum-sidecar","address":"0.0.0.0:7500","time":"2025-04-04T11:36:52+02:00","message":"gRPC server started"}
{"level":"info","module":"server","module":"ethereum-sidecar","startBlock":7828023,"endBlock":8048023,"time":"2025-04-04T11:36:52+02:00","message":"fetching AssetsLocked events from range"}
{"level":"info","module":"server","module":"ethereum-sidecar","time":"2025-04-04T11:36:53+02:00","message":"no new events to process"}

mainnet

Command:

/var/mezod/bin/mezod-v1.0.0-rc0/mezod ethereum-sidecar --log_format=json --ethereum-sidecar.server.ethereum-node-address="<redacted>" --ethereum-sidecar.server.network="mainnet"

This file is for mainnet, so what about hardcording mainnet value here?
As it is hardcoded for native

I think that the network name does not be placed in secret. It's not confidential information.
Actually, we don't need to define any new parametr in values.yaml.
We can add condition to the StatefulSet, as follows:

            - --ethereum-sidecar.server.ethereum-node-address=$(ETHEREUM_ENDPOINT)
            {{- if eq .Values.env.NETWORK "mainnet" }}
            - --ethereum-sidecar.server.network=mainnet
            {{- else if eq .Values.env.NETWORK "testnet" }}
            - --ethereum-sidecar.server.network=sepolia
            {{- end }}

Or we can add env.MEZOD_ETHEREUM_SIDECAR_SERVER_NETWORK to the values.yaml and use it:

- --ethereum-sidecar.server.network={{ .Values.env.MEZOD_ETHEREUM_SIDECAR_SERVER_NETWORK }}

Yeah, that sounds good, i will adjust it ;)
