No, it is not possible to receive USD directly into your Venn CAD account. However, the Wire (SWIFT) payment method is universal across your Venn CAD, USD, GBP, and EUR accounts. This means that if the sender transfers funds using Wire (SWIFT), the payment will be received and credited to the appropriate currency account.
For example, if the sender has sent you USD via Wire (SWIFT), the funds will be credited to your Venn USD account, not your CAD account.
