Solo-built stablecoin systems LMS that turns a Korean Obsidian research vault into a Next.js learning platform for issuance, redemption, signed payments, CCTP/L2 risk, RWA tokenization, account abstraction, x402 agent payments, security testing, and capstone labs.
What made the system difficult.
Needed to preserve the source vault as read-only evidence while converting it into structured LMS content with courses, lessons, exams, prerequisites, tasks, code labs, search, progress tracking, and admin review workflows.
How boundaries and flows answered it.
Built a Next.js App Router LMS with Prisma-backed learning state, Better Auth, Markdown/exam import scripts, source-boundary checks, admin monitoring/review pages, dashboard progress, public search, and Foundry-based stablecoin lab contracts.
The path of responsibility through the system.

Overview
- Solo-built blockchain LMS for stablecoin systems, settlement, security testing, L2/cross-chain risk, RWA tokenization, account abstraction, x402 payments, privacy, non-EVM systems, and infrastructure radar topics.
- The project began as a Korean Obsidian research vault and was converted into a database-backed web learning platform under a dedicated
web/app. - Live site: https://settlelabs.dev/
- Public repository: https://github.com/gwkim92/settleLabs
Product Surface
LMS Experience
- Next.js App Router pages for home, learn, lesson detail, exams, search, dashboard, sign-in/sign-up, and admin routes.
- Course navigation supports recommended path, full syllabus, and lab/task-focused views.
- Lessons include learning outcomes, prerequisites, completion criteria, tasks, source references, code blocks, visual blocks, and Mermaid diagrams.
Progress, Exams, and Reviews
- Prisma models cover users, sessions, courses, lessons, tasks, lesson progress, task submissions, notes, exams, questions, attempts, and answers.
- Users can complete lessons, submit tasks, track dashboard progress, and take course exams.
- Admin pages cover lessons, users, sources, reviews, and monitoring.
Content Pipeline
- Markdown course materials and JSON exam banks are imported into the database through TypeScript scripts.
- Source-boundary verification keeps the original vault as evidence rather than mutating it through the web app.
- Content audit scripts validate coverage and quality before publishing.
Lab Layer
- Foundry workbook contracts include a mock stablecoin, Permit checkout, ERC-3009 escrow, CCTP simulator, x402 payment server, and invariant tests.
- The lab layer ties conceptual lessons to executable settlement/payment scenarios.
Deployment Notes
- The production service is available at https://settlelabs.dev/ and is served through an nginx-fronted Next.js deployment.
- The repository is public and current on
main. - Runtime configuration uses standard Next.js scripts and environment variables for Better Auth, Prisma/SQLite, app URL, and seed admin credentials.
