No, if your bank belongs to the SEPA (Single Euro Payment Area), you do not incur any sort of commissions when topping up your wallet.
SEPA is the European system which harmonizes the payments in Euro currency in the 27 member-states of the European Union, as well as Iceland, Liechtenstein, Monaco, Norway, and Switzerland. In brief, it allows users to make payments in Euros in these countries, using a single bank account and benefiting from the same rules, rights, and obligations.
Given that our payment services provider MangoPay is based in France, if your bank is part of SEPA, you will not be subject to any additional costs.
Nevertheless, some banks charge commissions on inter-bank transfers (regardless of whether these are national or international). The same rule will therefore apply to transfers to your Goparity wallet.
On the other side, if your bank account does not belong to SEPA, it is likely that your bank will charge you a fee applicable to international transfers. Goparity has no say on those charges and therefore discards all responsibility for such costs.
Please note that your bank may charge you a fee if you choose to top-up your wallet with a credit card. To find out if you are subject to these fees and what the fees amount to, we recommend you get in touch with your bank provider.
