Why use stablecoin rails?
Cross-currency settlement through traditional rails is often slow and expensive. Stablecoin rails settled in under one second on our most recent build.
Can it support multiple currencies?
Yes. Multi-currency support was live from launch on our most recent build.
How fast can you ship?
Our most recent payment rails build shipped in five weeks. Your timeline depends on scope.
Is compliance included?
KYC/AML checks can be built into the payment flow. Regulatory sign-off stays with your counsel.
What is involved in stablecoin development for payments?
Choosing a chain, handling custody and settlement, and meeting compliance duties in each market. Stablecoin development and crypto payment gateway development both need a compliance plan, so we start from the FATF guidance on virtual assets.
