An interface is Lerian’s integration to a payment product. It gives you the API, the ledger integration, and the operational controls for that product.

What runs in production today

Pix runs in production through two interfaces. The JD interface connects your institution as a direct participant through a certified PSTI. The BTG interface connects you as an indirect participant.
