Unfortunately due to the finalilty of blockchain transactions and preservation of privacy, we cannot support chargebacks. It leads to unsustainable fraud. That is not just for Laso, but also our sub-issuers.
That's because a crucial part of the chargeback system is being able to determine and prevent fraudulent chargebacks. Because there isn't a way to enforce that fraud prevention, it's not possible to have that as part of our issuing program with issuing banks.
