Open Payment Infrastructure · v1.0

Accept Payments Instantly.
Keep Every Cent.

The Stablecoin Stack is the open infrastructure that lets payment processors, fintechs, and merchants accept digital currency payments with zero chargebacks, instant settlement, and no card-network fees — deployed under your brand, free to use.

Free & open source · Apache 2.0 · Fabric Payment Standards Foundation

Who is it for?

Built for the whole ecosystem.

Launch a payment processor without building the infrastructure.

The Stablecoin Stack is a complete, production-ready technical stack — settlement contract, checkout engine, payment gateway, merchant dashboard, browser wallet extension, mobile app. Deploy it under your brand and start earning from day one. No card-network royalties. No float held by intermediaries. Multiple revenue models available.

  • Instant, final settlement — seconds, not business days
  • No chargebacks by architectural design
  • Non-custodial option — significantly lower regulatory burden
  • Built-in acquirer model — on-chain partner commission distribution
  • Full stack on Docker Compose — run locally in minutes
  • Apache 2.0 — free to deploy, forever

Why it's different

Structural advantages that traditional rails cannot offer.

Instant, Final Settlement

Payments settle in seconds. The merchant receives their funds in the same session as the payment — not the next business day. No float. No clearing cycle.

🚫

No Chargebacks. Ever.

Payment authorisation is a cryptographic signature specific to the exact transaction. No intermediary can reverse it. The chargeback mechanism — and the fraud industry that exploits it — simply does not exist here.

🌍

Borderless by Default

A payment from any country settles the same way as a domestic transfer. No correspondent banks. No cross-border surcharges. No multi-day wires.

🔐

Non-Custodial Option

In non-custodial mode, funds move directly from payer to merchant. The processor is a relay, not a custodian — a fundamentally different regulatory profile from any traditional acquiring bank.

📖

Fully Open Standard

Every specification, every data structure, every conformance requirement is published under Apache 2.0. No licence fees. No lock-in. Governed publicly through the RFC portal.

💰

Multiple Revenue Models

Transaction fees, subscriptions, fiat conversion, acquirer commissions, float yield — nine processor models and six acquirer models, all enabled by the architecture.

Simple by design

A payment in five steps.

1

Merchant creates a charge

One API call. The checkout engine returns a QR code and session token.

2

Payer opens their wallet

Scan or tap. Payment details load automatically. No copy-pasting.

3

Payer confirms

Two signatures, produced on the device. Nothing moves without both.

4

Settlement contract executes

Atomic. Verifiable. Irreversible. Fees distributed in the same transaction.

5

Merchant receives confirmation

Webhook fired. Funds in wallet. Typically under 10 seconds total.

Fabric Payment Standards Foundation

Governed openly. Deployed freely.

The Stablecoin Stack is maintained by the Fabric Payment Standards Foundation — an independent non-commercial organisation dedicated to open payment standards. The specification is governed through a public RFC portal, not proprietary channels. Everything is Apache 2.0.
