EUDI Ecosystem Hackathon¶

June 4–5, 2026 · Fully remote · 48 hours

The German EUDI Wallet ecosystem is now open to all builders — no pre-approval required. For the first time, anyone can integrate directly with the sandbox: issue and verify EAAs, work with PID flows, and build real applications against the German EUDI Wallet infrastructure.

Join us on June 4–5, 2026 for a 48-hour hackathon across five challenge tracks. Winning teams will be invited to present live demos at the EUDI ON Conference on June 25, 2026 in Berlin.

Format¶

Dates: June 4–5, 2026
Format: Fully remote, 48-hour hackathon
Teams: Participate solo or as a pre-formed team; a dedicated Mattermost workspace will be provided for participants to find teammates and get technical support
Tracks: Five challenge tracks (see below) — teams may compete in any or all tracks
Judges: A panel of five judges will select the winning team per track
Winners: Up to three members of each winning team are invited to present in person at the EUDI Conference on June 25, 2026 in Berlin

Challenge tracks¶

🏛 Public Sector¶

Make government services seamless and citizen-friendly

Government services touch every citizen's life, yet digital interactions with public agencies remain fragmented and frustrating. How can the EUDI Wallet transform the citizen–government relationship through seamless, privacy-preserving digital services?

Example directions:

Benefits access and citizen ID portals
Age verification for regulated public services
Public sector authentication workflows
Re-registration and address change flows using PID

🏢 Private Sector¶

Build trust and reduce friction in business

Businesses face mounting pressure to verify customer identities, prevent fraud, and comply with regulations — all while respecting privacy and delivering seamless user experiences. How can the EUDI Wallet help businesses build trust with customers while reducing operational complexity?

Example directions:

AML-compliant onboarding and KYC flows
Insurance, mobility, and financial services integrations
Selective disclosure for privacy-preserving B2C verification
Employer onboarding with verifiable academic and professional credentials
Rental and car-sharing flows using PID and driver's licence EAAs

🔧 Builders' Challenge¶

Bridging the gap between digital identity and the physical world

Digital identity becomes truly powerful when it interacts with the physical world. How can EUDI Wallet credentials unlock, control, verify, or enhance interactions with real-world objects, spaces, and systems?

Note

This track requires tangible, physical interaction. Solutions must touch real hardware or IoT systems — purely digital flows do not qualify.

Example directions:

Wallet credentials that unlock doors or control access to spaces
Equipment access control (e.g. verifying authorisation before enabling machinery or tools)
Vehicle access and authentication using wallet credentials
IoT system control triggered by verified credential presentation
Physical check-in or event access tied to wallet-held credentials

🎨 Creative Applications¶

Reimagine what digital identity can do

Digital identity isn't just about proving who you are — it's about enabling new experiences that were previously impossible. How can the EUDI Wallet unlock creative use cases beyond traditional identity verification?

Example directions:

Gaming

Portable reputation systems: carry skill ratings or behavioural scores across games and platforms
Cross-game achievements: unlock rewards in Game B for achievements earned in Game A
Age-appropriate matchmaking: verify age ranges for safe multiplayer without revealing exact birthdates

Social & community platforms

Verified human badges to reduce bots
Proof of membership for niche communities (verified student, healthcare worker, etc.)
Dating apps: verified age, education, or profession credentials with user consent
Local community verification: prove residence for neighbourhood apps

Education & learning

Portable educational achievements, certifications, and course completions
Micro-credentials and digital badges for skills and workshops
Verified expertise levels for mentorship matching
Academic integrity: verified submissions for online exams and research

Health & wellness

Portable fitness achievements and certifications
Medical credentials for patients (allergies, blood type, vaccination records)
Wellness programme participation credentials for insurance discounts

Travel & experiences

Verified travel achievements and experience credentials
Verified reviews: prove you actually visited before reviewing hotels or restaurants

⚙️ Developer Tools¶

Make EUDI integration easier for everyone

Widespread EUDI adoption depends on making integration as simple as possible for developers. How can we build tools, libraries, and resources that reduce the effort and expertise required to integrate EUDI Wallet functionality?

Note

All entries in this track must be published under an open-source licence.

Example directions:

SDKs & integration libraries

Language-specific SDKs for JavaScript/TypeScript, Python, Java, Go, or .NET
Framework integrations for React, Vue, Angular, Django, Rails, or Spring Boot
Native iOS (Swift) and Android (Kotlin) libraries
Backend integration kits: verification endpoints, credential issuance flows, session management
Code generators that produce integration code from specifications

Testing & development tools

Test credential generators with configurable attributes
Automated integration testing suites
Debugging tools and credential exchange flow inspectors

Monitoring & operations

Analytics dashboards tracking issuance, verification attempts, success rates, and error patterns
Alerting tools for failed verifications or unusual patterns
Compliance reporting for audits

Developer experience

CLI tools for quick testing, credential generation, and deployment
Browser DevTools extensions for debugging EUDI flows
IDE plugins with code completion and inline documentation (VSCode, IntelliJ)

Open standards & interoperability

Community-contributed credential schema registries
Protocol bridges for interoperability with other digital identity standards
Format converters between credential formats
Compatibility layers for legacy systems

Jury¶

The winning team for each track is determined by a jury of five practitioners spanning standards development, policy, civil society, and engineering.

	Judge	Role
	Dr. Torsten Lodderstedt	PO, EUDI Project at SPRIN-D · Co-editor, OpenID for Verifiable Credential Issuance (OID4VCI)
	Marta Casaramona	UX/UI Designer, EUDI Project at SPRIN-D
	Dr. Markus Reichel	German Federal Parliament (Bundestag)
	Thomas Lohninger	Executive Director, epicenter.works
	Ali Salama	Tech & Learning, MotionLab.Berlin
	Ben Hesseldieck	VP Technology & Engineering, Code & Co. · Founding Engineer, n8n

Support & resources¶

A team of technical mentors from the EUDI Wallet and Ecosystem Infrastructure teams will be available throughout the hackathon via the dedicated Mattermost workspace and virtual office hours. Mentors cover both iOS and Android wallet development, as well as ecosystem infrastructure and protocol questions.

The developer documentation at this site — including the sandbox onboarding guide, credential format references, available open-source libraries, and protocol documentation — is your primary technical resource.
