Direct investments into your Vault via bank transfer or card payment are not currently possible.
To invest in your Vault, you must first transfer funds into your main SmartSaver account. Once the funds are available in your main account, you can easily move the desired amount into your Vault.
Also, please remember that you have a 10-day window to invest any additional funds into your Vault after it has been opened. This timeframe is important to keep in mind as you plan your investments.
If you have any questions about this process feel free to reach out!
