I built Relia with my teammate @bahago_json .
Relia turns installment payments into public title progress.
A buyer pays on Sepolia.
The shop acknowledges the exact payment.
Attestcoin proves both finalized facts.
Creditcoin updates the title slice.
No screenshots.
No private ledger.
No bridged payment funds.
Each asset has 12 slices.
Each valid payment + acknowledgement fills one slice.
If the shop stays silent, the payment is still visible and the slice becomes disputed instead of being rewritten as a missed payment.
We shipped:
- live Sepolia wallet flow
- shop acknowledgement flow
- Creditcoin title record
- public receipt verification
- judge evidence page
- 56 passing contract tests
- clear failure states like underpaid, wrong ack, closed window, reused payment
Relia is for hire-purchase and pay-over-time ownership where the buyer needs a record that survives beyond one shop’s database.
