Stellaroid Earn
On-chain credential trust for Stellar testnet
Issue, verify, and pay graduates - Soroban + Freighter, end-to-end.
Mark Siazon - Hybrid Product Designer & Full-Stack Developer
Certificates are easy to fake, hard to verify
- Bootcamp certificates are PDFs anyone can duplicate
- Employers skip verification or pay for background checks
- No standard way to prove completion on-chain
- Payment to graduates is disconnected from verification
No Trust
Anyone can forge a PDF certificate
Slow & Costly
Email threads and background check fees
Anchor credentials on Stellar
- Issuers register certificate hashes on Soroban
- Anyone verifies with a URL - no wallet needed
- Employers pay graduates in XLM on-chain
- Sub-cent fees + 5s finality
