Platform
Designed so your product, engineering and compliance teams work without friction.
Each certificate is registered on Polygon. The contract identifies its issuer and status; copying a file does not create a new authorized issuance.

recipient: '0x84e…',
course: 'Advanced Solidity',
metadata: { cohort: 'Q4-2025' },
});
// → token #1042 · soulbound · 42sFiles are published to IPFS. Pinning and hosting have ongoing costs; Arweave backup is optional and depends on configuration.
Arweave
hosted
Pinata
replicated
Signed events, exponential retries, idempotency by header.
Metadata uses explicit public fields. The PDF and image can contain personal data and require publication authorization.
Async queue, BullMQ and observability with OpenTelemetry.
Dynamic Open Graph, signed QR and embeddable badge.
Flow
No Web3 knowledge required. The crypto complexity is fully abstracted away.
Import the design, define the metadata and connect your institution. Our editor generates production-ready ERC-721 JSON.
Upload a CSV or call the /v1/certificates/issue endpoint. We process in batches and handle gas and retries for you.
Tessera mints on Polygon as an SBT (ERC-5192) and publishes metadata to IPFS, with optional Arweave backup.
Your student gets a link and a signed QR. Any recruiter verifies authenticity without creating an account.

Subscriptions are billed monthly and can be cancelled before the next charge. Monthly credits roll over up to two allowances; purchased top-ups do not reduce that grant.
TSC expires on the date of each credit lot. Expiry affects issuance balance, not the validity of certificates already issued. Top-ups use each package’s published price.
Issuance gas and file publication are included. Hosting and custody are provided while the service is operating, with no guarantee of preservation for 30, 60 or 100 years. Long-term continuity, archiving and migrations require agreed terms.
The promotional price is the recurring amount of this offer; no automatic increase is scheduled. Future changes require notice and the applicable purchasing terms.
Every certificate has its own URL with a verification QR, ready for your CV or portfolio.
The employer opens the link and checks its authenticity instantly, straight against the blockchain.
It arrives by email with a wallet already created for you. No seed phrases, no fees, no cryptocurrency.
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.).
