What This Is

learn.sol is a free, open-source learning product for developers who want to understand Solana by building through the stack.

It is not a loose list of tutorials. The product connects structured modules, executable exercises, runtime-focused tools, AI-assisted documentation, and a publishable agent skill into one learning loop:

1. Read a concept.
2. Practice it in code.
3. Inspect how the Solana runtime thinks.
4. Build the same idea visually.
5. Ask for help with source-grounded answers.

The goal is simple: help builders move from "I copied a Solana snippet" to "I can explain what accounts, signers, transactions, PDAs, token flows, and clients are doing."

Product Surface

Structured Modules

The curriculum is organized around the real Solana developer stack:

Module	Focus
Solana Foundations	CLI workflow, accounts, lamports, transactions, architecture, and a first devnet toolkit with @solana/kit.
Rust Foundations	Syntax, ownership, borrowing, structs, enums, collections, methods, and Solana-shaped Rust practice.
Anchor Programs	Local setup, program anatomy, constraints, PDAs, SPL Token, CPI, token minting, escrow, and ergonomics.
Solana Kit Clients	Wallet Standard, account reads, transaction messages, confirmation, Token-2022 flows, Anchor clients, transaction UX, and testing.

All lesson content lives under content/ and is rendered through Fumadocs MDX.

Executable Challenges

The challenge system is content-first and currently ships a 30-exercise Rust track under content/challenges/rust.

Challenges support:

• MDX-defined titles, descriptions, tags, starter code, and executor metadata.
• Monaco-based editing.
• Server-side validation through the Rust Playground API.
• Authenticated progress and completion tracking through Privy + Postgres.

Key files:

• lib/challenges/exercises.ts
• app/challenges
• app/api/challenges/run/route.ts
• app/api/challenges/progress/route.ts
• app/api/challenges/complete/route.ts

Runtime Lab

Runtime Lab is an interactive Solana runtime simulator for beginners. Learners predict what the runtime checks, reveal account diffs, inspect logs, and debug failure modes like wrong signers, owner mismatches, and PDA seed errors.

Runtime Lab currently includes a Vault Bootcamp flow and saves signed-in user progress.

Key files:

• lib/runtime-lab/flows.ts
• app/tools/runtime-lab
• app/api/tools/runtime-lab/progress/route.ts

Visual Builder

Visual Builder lets learners sketch Solana program architecture with drag-and-drop blocks for programs, instructions, transactions, signers, accounts, PDAs, token mints, token accounts, and CPIs.

It also includes local graph persistence and Anchor export helpers.

Key files:

• components/visual-builder/editor.tsx
• lib/visual-builder/blocks.ts
• lib/visual-builder/export-anchor.ts
• app/tools/visual-builder

AI and LLM-Ready Docs

learn.sol includes a documentation-aware chat route and LLM-friendly text endpoints:

• /api/chat streams AI answers with a documentation search tool.
• /llms.txt lists the docs corpus with canonical URLs and MDX links.
• /llms-full.txt returns a full text dump of the learning content.
• /learn/<slug>.mdx exposes markdown-friendly routes for individual docs pages.

Embeddings and search data use Postgres + pgvector.

Agent Skill

This repo ships a publishable Agent Skill that turns coding agents into Solana teachers.

Install it with:

npx skills add Some1Uknow/learn-solana --skill learn-solana

The skill lives in skills/learn-solana. It teaches Solana concepts from first principles with examples, diagrams, tables, exercises, and temporary HTML explainers.

Getting Started

Requirements

• Node.js 20+
• pnpm 10+
• PostgreSQL if you want auth-backed progress, embeddings, or DB-backed features
• A Privy app for local auth
• An OpenAI API key for chat and docs ingestion

Install

pnpm install

Configure Environment

Create a local .env file:

POSTGRES_URL="postgresql://user:password@localhost:5432/learnsol"

NEXT_PUBLIC_SITE_URL="http://localhost:3000"

NEXT_PUBLIC_PRIVY_APP_ID="your-privy-app-id"
NEXT_PUBLIC_PRIVY_CLIENT_ID="your-privy-client-id"
PRIVY_APP_ID="your-privy-app-id"
PRIVY_APP_SECRET="your-privy-app-secret"

OPENAI_API_KEY="your-openai-api-key"

# Optional
NEXT_PUBLIC_CLARITY_ID=""
NEXT_PUBLIC_ENABLE_REACT_SCAN=""

Run Locally

pnpm dev

Open http://localhost:3000.

Database

Generate migrations:

pnpm db:generate

Apply migrations through the safe migration wrapper:

pnpm db:migrate

Open Drizzle Studio:

pnpm db:studio

Rebuild Documentation Search

If lesson content changes and you need fresh embeddings:

pnpm ingest-docs

This requires POSTGRES_URL and OPENAI_API_KEY.

Content Workflow

To add or edit a lesson:

1. Add or update an .mdx file in the right module folder under content/.
2. Update that module's meta.json.
3. If the lesson should appear in the module catalog, update data/contents-data.ts.
4. Run the app locally and check the lesson route.
5. Run pnpm ingest-docs if search embeddings need to be refreshed.

To add a challenge:

1. Add an MDX file under content/challenges/<track>/.
2. Include frontmatter for title, description, track, slug, order, difficulty, tags, starterCode, and optional executor settings.
3. Use the existing Rust challenge files as the reference pattern.
