I am a payment processor or fintech¶
You want to deploy the Stablecoin Stack and offer payment services to merchants.
- Try the live demonstration. Before anything else, experience the full payment flow — browser wallet, simulated checkout, real-time settlement confirmation. Live Demo →
- Read the architecture overview. Understand the components you will operate, their roles, and how they interact. Architecture →
- Read the formal specification. SS-001 is the normative reference for everything — data structures, signing conventions, Settlement Contract interface, conformance requirements. RFC Portal
- Review the business model catalogue. Choose the revenue model that fits your market. Most new deployments start with the blended fee model (PP-3) and non-custodial settlement. Business Models →
- Run the stack locally. The full reference implementation is on GitHub with Docker Compose. Spin up the complete infrastructure on your machine in minutes. GitHub
- Contact the Foundation. We can connect you with other operators, point you to deployment resources, and list your processor in the public registry. Get in touch →
I am a merchant or online seller¶
You want to start accepting payments through a processor that runs the Stablecoin Stack.
- Experience it as a customer first. The live demonstration includes a simulated e-commerce checkout. Pay with the browser wallet extension or the mobile app, and see funds settle in real time. Try the Demo →
- Find a processor. The Foundation maintains a public registry of processors running conformant deployments of the Stablecoin Stack. Contact us for current availability in your region. Get in touch →
- Create a merchant account with the processor you choose. The onboarding process is comparable to any payment gateway — business details, settlement wallet, API credentials.
- Integrate the checkout API. The checkout engine speaks standard HTTP. If you have integrated any payment gateway before, this will be familiar. Your processor will provide documentation and test credentials.
- Go live. Your checkout will display a payment option for compatible wallet apps. Your processor will provide guidance on how to present this to your customers.
What to ask your processor
- Do you offer non-custodial settlement (direct to my wallet) or fiat conversion?
- What stablecoins do you support?
- What are your processing fees?
- What is your regulatory status in my jurisdiction?
I am a developer¶
You want to build something on the Stablecoin Stack — a wallet, a conformant processor component, an integration, or something entirely new.
- Run the stack locally. The GitHub repository includes the full reference implementation with Docker Compose files (
docker-compose.infra.ymlanddocker-compose.apps.yml). The entire stack — settlement contract, gateway, wallet, event explorer — runs on your machine. GitHub - Start with SS-001. The formal specification is the authoritative source. Read Sections 5–8 (component specifications and data structures) and Section 14 (validation rules) first. RFC Portal
- Read SS-002. If you are building a wallet or gateway integration, SS-002 specifies the WebSocket interface — message types, per-message authentication, subscription model, status lifecycle.
- Explore the Event Explorer SDK. The Event Explorer exposes a REST API for querying past settlement events and a WebSocket for real-time monitoring. An SDK is available, making it straightforward to build a local matching engine or analytics dashboard on top. Try it live →
- Contribute. If you find an ambiguity, a bug, or a gap, propose it through the RFC portal. All specification changes go through a structured public review process. Contribution guide
I represent a regulatory body or financial authority¶
You want to understand the Stablecoin Stack's properties — custody model, consumer protection, systemic risk profile — in the context of your regulatory framework.
The Foundation welcomes engagement with regulators. We can provide:
- A plain-language summary of the system's custody and authorisation model.
- The formal specification and reference implementation for technical review.
- Introductions to processors operating conformant deployments in specific jurisdictions.
- Responses to specific questions about the system's properties.

I want to contribute¶
The Foundation actively seeks contributors across all profiles. The specification is a living document — it improves through implementation experience, security review, and community feedback.
Propose changes, report ambiguities, or submit a new companion specification through the RFC portal. The portal is the single place for all governance-layer activity.
The reference implementation lives on GitHub. Open issues, submit pull requests, or build and share conformant components.
Join the Foundation's self-hosted community forum to discuss the specification, share implementation experiences, and connect with other contributors.
Organisations that depend on open payment standards can support the Foundation's work through a sponsorship membership.

The infrastructure is ready. The opportunity is now.¶
The Stablecoin Stack is live, specified, and open. The question is what you build on it.
