Unickeys
Unickeys is verifiable certificate infrastructure for companies. It turns any document into a public, tamper-proof record: issue it, hash it, register it on Solana, and let anyone verify it in seconds. No central database left to hack.
— The Challenge
Documents are no longer proof on their own. A PDF can be edited in minutes, issuer databases can be hacked or deleted, and verification still takes days. Companies needed a way to issue certificates, receipts, and contracts that anyone could validate in seconds, without depending on a central database that can be tampered with.
— The Solution
We designed and built Unickeys as B2B certificate infrastructure: authenticity, fraud, and verification in one platform. Companies issue documents with a unique QR and digital signature. Anyone can scan the QR or open a link to see the original data. An AI layer compares images or PDFs against the source record and flags inconsistencies even when a QR looks valid. Each file gets a SHA-256 hash, grouped into a Merkle tree, and written to Solana Mainnet, immutable and publicly verifiable.
— The Process
The product is built around a three-step path from zero to first certificate: create an account, connect the API with a single POST, and start issuing. We designed a public landing that explains the problem, the issuance-verification-fraud loop, and the cryptographic flow, document, SHA-256, Merkle leaf, Merkle root, Solana transaction, without requiring a blockchain background. Under the hood, batches of certificates share a Merkle tree so thousands of documents can be registered in one on-chain transaction.
Key features
- 01Verifiable certificates with unique QR and digital signature
- 02Public verification from any device in seconds
- 03AI fraud detection against the original record
- 04SHA-256 hashing and Merkle trees
- 05Immutable registry on Solana Mainnet
- 06API integration with a single POST

The Result
Unickeys lets a company go from signup to a production blockchain certificate in minutes. Documents become publicly verifiable, fraud is detectable automatically, and there is no central database to hack. The same infrastructure covers academic diplomas, HR certificates, legal contracts, property titles, and notarial records.
