Customers (Companies) cannot have multiple Wallets at a single time. Only 1 Wallet is allowed per Customer.
Within that Wallet, you can have multiple currencies enabled, which can be managed by the ATS in terms of what currencies the Customers see in the Marketplace and when placing orders.
If you do not see a Currency available that you believe should be, please reach out to your VONQ point of contact and we will check your account configuration to ensure it is available.
