AI-Powered Learning. On-Chain Credentials. Real Rewards.

Contracts · API · Frontend · AI · Indexer

ChainLearn is a personalized learning management system that rewards learners with on-chain tokens and verifiable credentials — built on Stellar with Soroban smart contracts.

We believe education is the gateway to financial inclusion. ChainLearn makes learning accessible, rewarding, and verifiable for anyone with a Stellar wallet — especially in emerging markets where traditional credentials are hard to obtain and easy to forge.

Connect Wallet → Pick a Course → Learn → Take a Quiz → Earn Tokens → Get Certified

1. Connect your Stellar wallet (Freighter, Albedo, LOBSTR)
2. Choose from AI-curated courses adapted to your background, goals, and pace
3. Learn with dynamic content generated by Cohere's LLM
4. Quiz and earn SEP-41 tokens for scores above 50%
5. Complete all modules and mint an on-chain NFT credential

Stellar's low fees make learning micro-rewards economically viable — something impossible on chains where gas exceeds reward value.

Three Soroban contracts power the on-chain layer:

• Learn Token — SEP-41 fungible token. Mints proportional rewards for quiz performance.
• Credential NFT — Verifiable course completion certificates stored on Stellar.
• Progress Tracker — Enrolls learners, tracks module completion and quiz scores on-chain.
