Stand up a hybrid vocational credential chain with non-transferable soulbound tokens and a public employer verification API. Credential fraud is eliminated and employers verify any candidate's skill certifications in seconds instead of days of manual checking.
Turn a paper vocational certificate into a portable soulbound credential any employer can verify through an open API.
01.
Issue each skill as a non-transferable token. The Soulbound Token module binds a vocational credential to the worker's wallet, so it cannot be sold or borrowed like a printed certificate.
02.
Anchor the holder. The DID and VC Ledger ties each credential to a verified worker identity, so an employer confirms who holds the skill and not merely that a certificate exists.
03.
Seal the achievement. The Provenance Notary anchors the course, skill level, and issuing body by digest, making a fabricated vocational certificate detectable against the record.
04.
Let any employer check in seconds. An open verification API resolves a credential to genuine or invalid, replacing days of phoning training centres to confirm a certificate.
05.
Accumulate credentials over time. Micro-credentials stack into a portable skill profile, so a worker carries a growing, verifiable record of competencies between employers and regions.
06.
Verify beyond one issuer. Because credentials live on a shared chain, a worker's certifications remain verifiable even when they move between training providers, sectors, or states.
Follow a single vocational credential from course completion through soulbound issuance to instant employer verification.

Cerulea decomposes micro-credential portability into modular contracts. Each layer records completion, mints a soulbound token, stacks the skill profile, and exposes a public API without any training provider mediating trust.
Portable micro-credentials are a horizontal capability. Here is how different actors put the credential chain to work.
Issue tamper-proof soulbound credentials that employers verify through an open API, protecting graduates against credential fraud and raising the market value of every certificate they award.
Key Asset Types
Verify a candidate's vocational certifications in seconds during hiring, filtering out fabricated certificates without days of phoning training centres to confirm.
Key Asset Types
Carry a portable, stackable profile of verified skills between employers, sectors, and regions, so competencies earned anywhere remain provable everywhere.
Key Asset Types
Whether you are bridging a training provider's course system or issuing credentials to worker wallets, Cerulea routes both onto one hybrid credential chain.
For training providers on existing course systems. Completion events are translated into soulbound credential mints through the API gateway automatically.

Building a hybrid credential chain with soulbound micro-credentials, a stackable skill profile, and a public verification API from scratch requires specialised smart-contract engineers and long audit cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects hybrid-chain development benchmarks. Writing soulbound credential logic, building a stackable skill profile, and shipping a public verification API for an average provider takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your credential and profile rules into pre-audited WebAssembly binaries and provisions the credential chain and verification API instantly.
