This is an Andamio credential badge.

Not a picture in someone else's database — a credential you can read, own, and verify.

A real, verifiable, on-chain credential. The course ID and SLT hash are the Cardano record — copy them, open the course on Andamioscan, or scan to verify.

LOOK INSIDE

Select a field to see what it encodes. The rings are the course id and the learning-target hash.

Anatomy01 / 05

It looks like a badge. The interesting part is what refuses to stay a picture.

Access-token and global-state validators, reviewed for token theft, protocol halting, datum malformation and double satisfaction. Six findings; five resolved, one acknowledged by design.

01 / 04The problem

Most digital badges are rented pictures.

They look finished. They rarely travel, prove, or outlive the vendor.

PDF certificate

issuer: A logo in the corner
evidence: None attached
reviewer: Unknown
verify: Email the issuer and wait
lives in: A vendor's database

Andamio credential

issuer: did:web:credentials.andamio.io
evidence: Learning targets, hashed into the badge
reviewer: Recorded with the claim
verify: Anyone, on-chain, any time
lives in: The earner's wallet

Andamio Issuer

Keep the signal, tune out the noise, and make every credential yours. Andamio Issuer is a lightweight API that integrates with your existing systems in minutes. You keep your existing infrastructure, get everything a blockchain guarantees, and decide how visible the blockchain is to your people.

Property 01

Permanent

It outlives whoever issued it.

Property 02

Useful

Software can act on it, not just look at it.

Property 03

Yours

You define what it means. The earner keeps it.

Property 04

Proof

The work and its review travel inside it.

Two ways to adopt

How visible the blockchain is to your people is your call.

Invisible blockchain

wallets: Created for each user at sign-in
fees: Sponsored by the organization
user sees: Your product and your sign-in
example: Barça Vision Lab — fans sign in with BarçaID

Visible blockchain

wallets: Earners connect their own Cardano wallet
fees: Paid by the wallet holder
user sees: Their wallet, their credential, on-chain
example: Contributor programs, Andamio app

Define targets, walk an illustrative issue and verify — then continue to the real product when you are ready.

Andamio Developers

Every credential, course, and access rule on Andamio is reachable through one API. Transaction building is abstracted into a clean set of endpoints, so the hardest blockchain work is already done. Your users can connect their own wallet, or you create wallets and sponsor transactions so they never see one. Andamio API delivers a new set of primitives and leaves the creative parts to you.

API

Build on Andamio

Courses, projects and credentials as endpoints. Transactions come back ready to sign.

04 / 04Ecosystem

A credential badge means something in your world first, then it goes further than you do.

Portable

Andamio Credential Badges are owned by earners and verifiable anywhere — each one travels with the person who earned it, not from them. Other project teams, organizations, clubs, or coalitions can decide to make them useful in new ways.

Build with the API →

Agent ready

Credential Badges can be issued to agents that prove their capabilities, taking the guess-work out of agent delegation and access control.

In research

Your data

Andamio doesn't track how your badges are shared or viewed. That analytics layer is yours: keep the one you have, or build your own. What the protocol records are the interactions behind each credential — defined, evidenced, reviewed, claimed. Nothing more.

Community

Andamio is built in the open, with the people using it. Join the conversation, help shape the roadmap, and build alongside other teams.

People want to trust each other. We are building an internet where they can.

At its core, Andamio is built on one idea: you should be able to write the rules. You say what a credential means, who reviews the work, and what it unlocks in your organization or the apps you are building.
