The thesis

Stablecoins shouldn't need fifty engineers.

Cards, banks, FX, payouts, compliance. Each one a separate vendor. Each one bleeds time and money before a single customer transacts.

HashDT collapses the stack into one API and one white-label dashboard. You plug in, brand it, ship it — your customers see your name while we handle everything underneath. And every endpoint is MCP-ready from day one.

Why HashDT

Ship new and compliant products faster.

One integrated platform that carries the regulated plumbing, so you can focus on your customers.

Complete stack

Cards, banking, FX, payouts, API and MCP in one place — the flexibility to build every money feature without stitching vendors.

Fully white-label

Your logo, colors, domain and card art across dashboard, emails, statements and mobile. HashDT is invisible by design.

Own your customer

A B2B2X model — your customers sign with you and see your name. We never appear in their inbox or on their bill.

Compliance handled

We carry the program — BSA/AML, KYB, KYC, sanctions screening. You inherit it as a sponsored partner.

Launch in 14 days

Simple docs, developer tools and guides take you from sandbox to first live transaction in days, not quarters.

Scalable & secure

Multi-region active-active, scoped keys, and a 99.99% target SLA — trusted from first call to nine figures of volume.
