Thank you for contacting Ask Mastercard.
Mastercard does not have any affiliations or partnerships with any cryptocurrency companies at the moment.
Could you please indicate to us where you have seen the Mastercard logo in this ‘promotion’ and/or on this company’s website?
That's OK. Have you even read Hash Card whitepaper or visited their Telegram?
The Hash Card team explicitly states they DO NOT HAVE partership with Mastercard.
This is because Mastercard does not allow direct partership with cryptocurrency projects.
That's why they needed to do it indirectly. Hash Card has partnership with a bank, that has partnership with Mastercard.
