Turn a downloadable PDF certificate into a non-transferable public-chain token any employer can check independently.
01.
Issue each certificate as a non-transferable token. The Soulbound Token module binds the credential to the learner's wallet so it cannot be sold or handed to another person, unlike a shareable PDF.
02.
Anchor the holder. The DID and VC Ledger ties each certificate to a learner identity, so a verifier confirms who earned the credential and not merely that one exists.
03.
Seal the achievement. The Provenance Notary anchors the course, completion date, and issuing platform by digest, making a forged certificate detectable against the on-chain record.
04.
Let employers check without the platform. A public verification portal resolves a certificate to a genuine or invalid result, so the platform is not a bottleneck or a single point of trust.
05.
Represent skills as portable badges. Stackable badges are minted alongside certificates, letting learners assemble a verifiable public profile of completed courses.
06.
Make credentials outlive the platform. Because certificates live on a public chain, a learner retains verifiable proof of completion even if they leave the platform or it changes hands.
Follow a single course completion from a learner finishing the course to independent verification by an employer.

Cerulea decomposes certificate issuance into modular contracts. Each layer records completion, mints a soulbound token, issues badges, and exposes independent verification without the platform mediating trust.
Independent certificate verification is a horizontal capability. Here is how different actors put the public-chain issuance dApp to work.
Issue globally verifiable certificates that employers check without contacting support, turning credential integrity into a differentiator and removing the platform as a verification bottleneck.
Key Asset Types
Confirm a candidate's completed courses on the public chain during screening, eliminating fake certificate PDFs and the need to email a learning platform for confirmation.
Key Asset Types
Recognize platform certificates toward continuing-education requirements from a verifiable record, streamlining member accreditation without manual certificate collection.
Key Asset Types
Whether you are issuing from a learning platform backend or letting learners hold certificates in a wallet, Cerulea routes both onto one public-chain credential record.
For learning platforms on existing course systems. Completion events are translated into soulbound certificate mints through the API gateway automatically.

Building a public-chain certificate dApp with soulbound tokens, stackable badges, and an independent verification portal from scratch requires specialised smart-contract engineers and long audit cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects public-chain dApp development benchmarks. Writing soulbound token logic, building a badge system, and shipping an independent verification portal for an average platform takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your issuance and badge rules into pre-audited WebAssembly binaries and provisions the public certificate registry and verification portal instantly.
