Stellaroid Earn
On-chain credential trust for Stellar testnet
Issue, verify, and pay graduates - Soroban + multi-wallet, proof to payment 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

A trust gap worth closing
Credentials are unverifiable
Bootcamp and course certificates are PDFs. Employers trust them blindly or pay for background checks.
Graduates lack portable proof
Millions finish online programs each year with nothing an employer can confirm in seconds.
Stellar makes it economic
Sub-cent fees and ~5s finality make anchoring each credential - and paying graduates directly - viable where gas-heavy chains can't.
Our wedge: bootcamps and training providers as issuers, employers and recruiters as verifiers - starting where credential trust and cross-border payout friction are highest.
How it spreads
Zero-friction verification
Employers check a credential from a shared link or QR - no install, no account. Every shared proof is a live demo.
Pilot-led onboarding
The /pilot form captures training providers; first rollouts stay small (5-10 credentials) to prove the loop before scaling.
Ecosystem distribution
Stellar PH + Rise In community, testnet-first to lower adoption risk, installable PWA for checks on the go.
What's next
Keep it reliable
Green E2E for register, verify, and pay; testnet clarity; no scope creep.
Useful after the event
Issuer onboarding, proof-to-employer handoff, /pilot capture, honest talent passports.
Pilot with real users
One real issuer, 5-10 live credentials, employer feedback on proof clarity and trust.
Product decisions
Mainnet feasibility, standards signing, indexing - each gated behind written policy, not rushed.
Deliberately not now: no marketplace, no mainnet from examples, no NFT layer before real issuer demand is validated.
