Credentials That
Belong to You
An open protocol for interoperable credentials.
FOR DEVELOPERS
Build apps anchored on interoperable credentials.
Andamio handles the blockchain.
You send an API request. We build the transaction, validate the scripts, and submit to Cardano.
View Full API Reference →# Claim a credential
curl -X POST \
api.andamio.io/api/v2/tx/course/student/credential/claim \
-H "X-API-Key: $ANDAMIO_API_KEY" \
-d '{
"alias": "alice",
"course_id": "d7d6c8a9..."
}'
# 200 OK — sign this with any Cardano wallet, then submit
{ "unsigned_tx": "84a700..." }WHAT YOU CAN DO
Your app. Shared credentials. Users own the proof.
Issue
Define credentials that mean something in your context. Anyone can issue. Recipients carry them across every app on the protocol.
Verify
Check any credential, from any issuer, in real time. On-chain records mean no phone calls, no PDFs, no trust required.
Gate
Use credentials to unlock content, roles, or rewards. Build learning paths, contributor programs, or access tiers — all anchored on proof.
HOW IT WORKS
Andamio is built on Cardano.
Your app is built on Andamio.
Role-based access, credential gating, and contribution tracking — on a layer you don’t have to build yourself.
YOUR APP
You build this — your frontend, your experience, your users

WHY ANDAMIO
What you get. What it costs.
| Ownership | Credentials belong to the recipient. Portable across every app on the protocol. |
| Cost | Free tier to start. No per-user licensing. On-chain costs scale with usage. |
| Privacy | Personal data stays off-chain. Only credential proofs are recorded. |
| Wallets | Users don’t need one. Organizations sponsor transactions. Blockchain is invisible. |
| Durability | Credentials survive on Cardano mainnet regardless of any single platform. Open source. |
| Integration | REST API. Add credentials to your existing app without learning Cardano. |
*Approximate on-chain costs. Actual costs depend on transaction complexity and network conditions.
FAQ
Common questions
The API is for developers building their own applications — bring your own frontend, your own UX. The App is a hosted solution for organizations that want to get started without writing code. Think Stripe vs. Shopify.
No. Email signup. Your organization sponsors transactions. The blockchain is invisible to your users.
Your credentials survive. They're permanent records on Cardano mainnet — open source, verifiable by anyone, with or without Andamio.
Yes. Smart contracts audited by TxPipe. 152 end-to-end tests. Live on Cardano mainnet since February 2026.
