No, it's not a new-fangled fruit-based currency, although in this age of crypto it really wouldn't surprise us. MANGOPAY is actually a secure and trusted third-party financial services provider but we can appreciate that some banks may not have heard of them. Don't panic though, they’re on our side!
MANGOPAY is an FCA-regulated electronic money institution (EMI) that manages our secure escrow payment service. The actual bank account used for our secure UK payments is a UK-based Barclays Corporate Account, owned and operated by MANGOPAY. For all EU payments, the bank account used is a French based Arkea Bank Account, owned and operated by MANGOPAY.
MANGOPAY was created in 2013 and is approved as an EMI by the Financial Sector Regulator (CSSF). MANGOPAY's head office is in Luxembourg and is a legit organisation so worry ye not.
