Overview

Digital credentials, complete with no system to build

Issue credentials on the web with no system to build, and confirm authenticity instantly with one QR code. Works for diplomas, completion certificates, appointment letters, and licenses.

  • TAMPER-PROOF

    Tamper-Proof

    Recorded on the blockchain at issuance, so any change shows up as a mismatch with the original.

  • VERIFY

    Instant Verification

    A single QR code instantly confirms whether a credential is original and untampered.

  • ISSUE

    Easy Issuance

    Just register a recipient list, and hundreds of credentials can be issued at once.

Workflow

Upload, issue, verify. Done

Register a template and recipient list, and issuance through QR verification runs automatically.

  • 01

    Register template & recipient list

    The issuer creates a template and bulk-uploads recipients as CSV, preparing many credentials at once.

  • 02

    Issue & record on-chain

    Credentials are issued automatically from the list, with the original and its hash recorded on the blockchain. Later changes show up against the original.

  • 03

    Receive & verify instantly

    Recipients get their credential by KakaoTalk or email, and receiving organizations confirm authenticity by QR code or link. No extra software needed.

Core Features

Notifications, status tracking,
and billing, all in one

  • NOTIFY

    Automatic Notifications

    Notifications go out automatically by KakaoTalk and email when a credential is issued. Staff need not contact anyone individually, and recipients learn at once how to verify it.

  • DASHBOARD

    Issuance Dashboard

    See issued, revoked, and expired credentials at a glance in one dashboard. Several staff can review issuance records together.

  • USAGE

    Usage-Based Billing

    No subscription fee. You pay only for credentials you issue, so low-volume organizations start with no upfront cost and scale when needed.
