About.
Unter runs the full crypto engine behind your brand.
Our purpose
Unter runs the full crypto engine behind your brand. Wallet connect, routing, swaps, bridging and settlement all happen in the background. Your merchants simply receive the correct token on the correct chain. Your users complete a payment without friction. We believe crypto payments should feel as simple and predictable as paying with a card. Our role is to make that possible.
Unter is invisible on purpose. Your brand stays in front. Unter works behind the scenes to keep every transaction reliable and secure. The platform is non custodial, so funds move directly from the user wallet to your platform. Security, uptime and monitoring are built into the core of the service. Every step of the payment is tracked and transparent for your team.
Why platforms choose Unter
Platforms and PSPs use Unter because it removes the hardest part of crypto acceptance.

Platforms like GSX, Payhub and more use Unter to support global merchants with a fully branded crypto checkout. They receive the correct settlement every time. Their support load drops. Their revenue grows.
We continue to expand the Unter engine with new chains, faster routing and upcoming features like refunds, dashboards and gas abstraction.
Our goal remains simple:make crypto acceptance effortless for PSPs and their merchants.
