RetryAttempts is how many attempts are made to reconnect to an Ethereum client before failing.

const RetryAttempts = 60 * 60

RetryDelay is the delay between reconnects to an Ethereum client.

const RetryDelay = 1 * time.Second

var ServiceDelayType = retry.DelayType(func(n uint, err error, config *retry.Config) time.Duration {
    return retry.FixedDelay(n, err, config)
})

var ServiceRetryAttempts = retry.Attempts(RetryAttempts)

var ServiceRetryDelay = retry.Delay(RetryDelay)
