There is no minimum deposit for bank transfers. For card transfers, a minimum amount of CHF 300 is requested for both the initial funding and subsequent deposits. For new clients who are verifying their account via document upload, the initial funding has to be made via bank transfer. Once the account is activated, credits cards can be used for subsequent deposits. The minimum card deposit in other currencies is displayed on the payments screen when you go to process a payment.
If you want to pre-credit your account urgently after a bank transfer (eg when you’ve received a margin call) you can upload proof of payment.
