	// The duration for submitting a withdrawal transaction to L1 can last up to 24 hours. For additional information,
	// please refer to the documentation: https://era.zksync.io/docs/reference/troubleshooting/withdrawal-delay.html.
	// Once the withdrawal transaction is submitted on L1, it needs to be finalized.
	// To learn more about how to achieve this, please take a look at the 04_finalize_withdraw.go script.
