About

We're building the billing layer crypto should have had from day one.

Card networks gave the internet a decade of growth. Stablecoins are quietly doing the same for the next one — and they deserve infrastructure that matches what the best B2B SaaS teams have come to expect from Stripe. OpenSettle is that infrastructure.

Principles

Why we built it this way.

Never hold your money.

Custody is a regulatory, operational, and reputational cost. We opted out, by architecture.

Build for engineers.

Typed SDKs, idempotent webhooks, a real CLI. If it takes an afternoon to integrate, we did it right.

Charge fairly.

A single fee on volume, paid in the same transaction. No reserves, no minimums, no rent-seeking.

Be boring where it matters.

Audited code, signed everything, SOC 2 paperwork on request. Novelty belongs in the product, not in compliance.

Ship on every chain that matters.

Six networks at launch, easy to add more. We never want a chain migration to be your problem.

Respect your customers' wallets.

Self-custody is a real constraint. We build every autopay mode instead of pretending cards don't exist.
