	CommandSync(ctx context.Context, cmd txn.Command, payload proto.Message, f func(string, error), bo *backoff.ExponentialBackOff)
}

type Config 

type Config struct {
	// Level specifies the logging level of the Event Forwarder engine.
	Level                                    encoding.LogLevel `long:"log-level"`
	RetryRate                                encoding.Duration `long:"retry-rate"`
	KeepHashesDurationForTestOnlyDoNotChange encoding.Duration
	// a list of allowlisted blockchain queue public keys
	BlockchainQueueAllowlist []string `description:" " long:"blockchain-queue-allowlist"`
	// Ethereum groups the configuration related to Ethereum implementation of
	// the Event Forwarder.
	Ethereum   ethereum.Config   `group:"Ethereum"   namespace:"ethereum"`
