Welcome to Andamio

Andamio is an open protocol for credential-gated collaboration on Cardano. Create courses that issue verifiable credentials. Launch projects where qualified contributors earn rewards. Build applications that read and write to shared, auditable state.

Build on Open Credentials

Issue interoperable credentials via API
Cardano is always the source of truth
Your users own their credentials; your app just reads them

Getting Started

Clone the app template and run locally in 15 minutes

API Quickstart

Make your first API call in 5 minutes

What Can You Build?

Treasury Governance

Credential-gated access to shared funds. Verified contributors unlock spending and delegation.

Onboarding Platforms

Guide team members through structured learning paths. Issue credentials as they progress.

Coordination Infrastructure

For guilds, collectives, and DAOs. Credentials define permissions and decision-making authority.

Co-op Social Media

Community-owned platforms where credentials control moderation, curation, and governance.

These are just a few ideas. Andamio is built for you to create your own systems and tools. If you want to explore what's possible, join Andamio Pioneers where builders share what they're making.

Developer Guides

Guide	Description
Your First App	Build a course, enroll a student, submit an assignment
API Integration	Environment URLs, auth headers, request patterns
Authentication	Wallet-based login and JWT flow
Transactions	Build → sign → submit lifecycle
Error Handling	Recovery patterns for failed transactions

Built-in Access Control

The API separates app identity from user identity:

Header	Purpose
`X-API-Key`	Identifies your app. Used for rate limits and quotas. One key serves all your users.
`Authorization`	Identifies the user. A JWT issued when users sign a challenge with their Cardano wallet.

Users never expose private keys or sign transactions during authentication. They sign a challenge, nothing more. Tokens are valid for 24 hours.

Want to Try Andamio First?

Before you build, experience the platform as a user. Mint an access token, take a course, earn a credential. Takes about 2 minutes with a Cardano wallet (Nami, Eternl, or Lace).
