Credentials that belong to you.
An open protocol for interoperable credentials.
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.

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.
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.

What Andamio gives you.
Six guarantees of the protocol — the same whether you build with the API or work directly with the smart contracts.
- Ownership
- Credentials belong to the recipient. Portable across every app on the protocol.
- Accessibility
- No per-user licensing. Start building without upfront commitments.
- 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.
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.
V2 is live. We’re still building.
