The setup for savings sponsors to make deposits into the kids account is handled directly by the legal guardians within the client area.
As the legal guardian, log in to your client area and navigate to Profile > Your Children and select "Invite savings sponsor" You can add up to six sponsors. To do this, you will need the person's name and the IBAN of the account from which the deposits will be made. In the final step, select the specific product for the child that is to be funded. Once the setup is complete, the authorized person is permitted to make transfers to the child's account.
Important: The activation as a sponsor exclusively authorises deposits. Sponsors receive no access to the Kid's account, its assets, or the ability to carry out trades or withdrawals.
