Platform
The complete infrastructure for issuing credentials with superpowers.
Designed so your product, engineering and compliance teams work without friction.
Soulbound · ERC-5192
Credentials that cannot be transferred or forged.
Every certificate is minted on Polygon through our standard, reviewed by OpenZeppelin. Neither the owner can resell it, nor a hacker clone it.

API · 99.9% uptime
Latency under 60s end-to-end.
Async queue, BullMQ and observability with OpenTelemetry.
Public verification
Share a link, turn verification into marketing.
Dynamic Open Graph, signed QR and embeddable badge.
Flow
From template to public QR in four steps.
No Web3 knowledge required. The crypto complexity is fully abstracted away.
- Step 01
Upload your template
Import the design, define the metadata and connect your institution. Our editor generates production-ready ERC-721 JSON.
- Step 02
Launch an issuance
Upload a CSV or call the /v1/certificates/issue endpoint. We process in batches and handle gas and retries for you.
- Step 03
We mint on-chain
Tessera mints on Polygon as an SBT (ERC-5192) and publishes metadata to Arweave + IPFS with double pinning.
- Step 04
Public verification
Your student gets a link and a signed QR. Any recruiter verifies authenticity without creating an account.
Plans
Honest pricing. No surprises on gas.
You pay the subscription, we absorb the gas on Polygon. Each certificate consumes exactly 2 TSC.

FAQ
Objections answered before your first issuance.
This part matters too: blockchain, compliance and payments usually sound complex. Here we make it clear, direct and verifiable for a serious buyer.
Built for institutional sales
Compliance, custody, gas and operational continuity
No. Tessera creates custodial wallets by default. If a student wants full autonomy, they can link their own wallet (MetaMask, Coinbase, etc.).
