GA_CHAIN_IDwill map to the command line flag
--chain-id. Note that while explicit command-line flags will take precedence over environment variables, environment variables will take precedence over any of your configuration files. For this reason, it's imperative that you lock down your environment such that any critical parameters are defined as flags on the CLI or prevent modification of any environment variables.
