Educhain is an Arghafy R&D mobile app that helps universities verify student graduate attributes, such as digital fluency or teamwork, with sign-off from an industry partner. Once approved, a submission is cryptographically signed by the student and recorded with a blockchain transaction hash, giving the university a credential record that cannot be quietly edited later.
Case study
See why this system matters, how Arghafy shapes delivery, and what clients can expect.
Business problem
Universities often certify graduate attributes, soft skills like teamwork, adaptability, or digital fluency, through self-reported checklists that employers and accreditation reviewers cannot independently verify. Paper-based sign-off from industry partners is easy to lose, backdate, or falsify.
Arghafy solution
Arghafy built Educhain as an in-house R&D initiative: students submit evidence for a graduate attribute, an industry partner (Mitra) reviews and validates it, and approved submissions are signed and recorded on-chain, giving universities a verifiable, tamper-resistant record of student competencies beyond the transcript.
Timeline estimate
Built as an internal R&D initiative. A white-label rollout for a university typically takes 10-16 weeks depending on the number of graduate attribute categories, wallet/identity requirements, and industry partner onboarding.
Best fit customer
Universities, polytechnics, and industry-partnership programs that want verifiable, employer-trusted records of student competencies beyond transcripts.

Educhain Modules
Each module supports the verification flow: students submit evidence, industry partners validate it, and the result becomes a tamper-resistant record.
Students select a graduate attribute category, such as Digital & Technology Fluency, upload supporting evidence, and track submission status from their dashboard.
Industry partners review submitted evidence, approve or reject with written feedback, and sign off on validated attributes.
Approved submissions are signed with a cryptographic student signature and recorded with a blockchain transaction hash, so a validated credential cannot be quietly edited later.
Students and Mitra connect a crypto wallet via WalletConnect/Reown AppKit, using ethers.js and viem for signing and on-chain interaction.
Student, Mitra, and University roles see different dashboards and permissions, from submitting evidence to reviewing institution-wide attribute records.
A Node.js/Express API with Prisma ORM and PostgreSQL handles authentication, submission storage, evidence uploads, and rate-limited, helmet-secured endpoints.
Arghafy approach
Arghafy can build from scratch, improve existing applications, or connect websites and internal tools into one cleaner workflow.
