§Timeline

Month 1 — August 2026: User Research and Planning

User research with potential participants · identification of literacy, language, technology and navigation barriers · definition of the basic receive, confirm and pay flows · participant recruitment · technical planning and MVP requirements

Month 2 — September 2026: Backend and Lightning Development

Development of the backend architecture and core service layer · connection to Lightning infrastructure · implementation of invoice generation, payment confirmation and payment sending · transaction status and error handling · creation of a secure testing environment · internal technical testing using small amounts of sats

Month 3 — October 2026: Visual Interface and Prototype

Visual interface design · creation and evaluation of recognizable icons · development of simplified and visually guided payment flows · connection of the interface to the functional backend · creation of the first interactive Android prototype · early feedback from potential users and Bitcoin educators

Month 4 — November 2026: Supervised Usability Testing

Initial supervised testing sessions · practical receive, confirm and pay tasks · small-sat Lightning transactions · measurement of comprehension, errors, completion time and assistance required · identification of confusing icons and payment steps · technical and interface improvements

Month 5 — December 2026: Community Pilot and Reporting

Real-world testing in Monte Cristi and other participating communities · supervised sessions with 30 Dominican and Haitian participants · final interface and technical improvements · analysis of results · documentation and public reporting

§Implementation Approach

Zanmi Mwen will use recognizable icons, simplified screens and visually guided payment flows to reduce dependence on written instructions.

Thirty participants will complete supervised tasks such as:

• Receiving sats.
• Confirming that a payment arrived.
• Opening or scanning a Lightning payment request.
• Paying with sats.
• Recognizing successful, pending or failed transactions.

Testing will measure:

• Understanding of icons and payment steps.
• Task completion rates.
• Errors made during each task.
• Time required to complete each action.
• Amount of assistance required.
• Participant confidence.
• Differences related to language, literacy and technology experience.

Monte Cristi will serve as the first real-world testing environment, with additional sessions conducted in other participating communities. The pilot will include Dominican and Haitian participants to evaluate whether the visual interface can support users with different language and literacy backgrounds.

Testing will use small amounts of sats under supervision. Participants will not be required to use significant balances or provide private financial information.

§Implementation Team

Tokio: Backend and Android development, Lightning integration, technical architecture, internal testing and technical documentation.

Sandra: User research coordination, participant recruitment, community relationships, supervised testing, observation and follow-up.

Escuelita Bitcoin: Co-design, accessibility guidance, participant support, usability testing and feedback analysis.

Andy Creed (@andycreed0x): Software developer, Bitcoiner and founder of WapuPay. He will participate as an independent technical consultant, providing feedback on the product architecture, functionality and security.

Bluemoon (@moon33_blue): Developer from Librería de Satoshi. She will participate as an independent technical consultant, reviewing the MVP and providing technical and security feedback.

Andy Creed and Bluemoon are not members of the SST development team and will not be responsible for building the product. Their role will be limited to independent technical consultation and product review.

§Expected Bitcoin Impact

By December 2026, the project expects to produce:

• One functional visual-first Android Lightning MVP.
• Basic receive, confirm and pay functions.
• Supervised testing with 30 Dominican and Haitian participants.
• Real Lightning transactions using small amounts of sats.
• Evidence about comprehension, errors and assistance required.
• Interface improvements based on direct user feedback.
• Independent technical and security feedback.
• Public documentation of the development and testing process.

Success will not be measured through downloads. It will be measured by whether participants can understand the payment process, complete basic Lightning tasks and recognize when a payment has been successfully received or sent.

The results will help determine whether a visual-first interface can reduce barriers for first-time Lightning users and guide the next stage of Zanmi Mwen’s development.

§How We Will Use the Funds

40% — Backend, Android Development and Lightning Integration

Backend architecture, core wallet services, Lightning integration, invoice generation, payment confirmation, payment sending, error handling, Android implementation and internal technical testing.

20% — User Research and Supervised Testing

Participant recruitment, research sessions, community coordination, supervised usability testing, observation, feedback collection and analysis.

15% — Visual Interface and Icon Design

Icon development, simplified payment flows, interface design, interactive prototyping and improvements based on user feedback.

10% — Android Testing Devices

Devices required to test the MVP across different screen sizes, Android versions and user environments.

10% — Bitcoin Infrastructure and Technical Services

Lightning infrastructure, test sats, development resources, independent technical consultation and the technical services required to build and evaluate the MVP.

5% — Documentation and Public Reporting

Documentation of the development and testing process, results, limitations, social media updates and a public report.

Every contribution will support the creation and evaluation of a testable Lightning MVP and generate practical evidence about making Bitcoin payments more understandable and accessible.
