Marketplace integration

Enable your cross-border sellers to instantly open in-country currency accounts to collect sales proceeds locally from your platform.

These accounts are fully embedded and managed within your marketplace seller portal, which enables merchants to view balances, pay suppliers and manage FX and payments without getting distracted from the main task of selling.

If you’re an established Tier 1 MSB or bank, our APIs may be able to support your global growth ambitions.

We can offer you and your clients improved global payment capabilities and a global currency account solution all integrated into your existing user interface.

We may also be able to rely on your existing KYC processes to make the sign-up process for your existing clients as smooth as possible.
