WE BUILD

WE BUILD is a European consortium building the infrastructure for a fully interoperable EU Digital Identity Wallet for businesses, bringing together more than 350 participants from over 180 organisations across 30 countries.

The consortium works through use cases rather than specifications alone: thirteen of them, including cross-border company registration, creating a company branch in another member state, supplier onboarding and fraud prevention, which are the procurement and compliance problems organisations run into every day. Its Interoperability Test Bed is where that work is checked: wallets, issuers and verifiers are tested against the protocols and profiles the ecosystem will run on, OpenID4VCI, OpenID4VP and the EUDI Wallet standards, so an implementation that passes works with the others rather than only with itself. Credenco contributes as a beneficiary partner in the work package on wallets for business, and its Business Wallet has cleared every test case of the test bed. WE BUILD is funded through the Digital Europe Programme as one of four Large Scale Pilots that ran alongside the EUDI Wallet reference implementation between 2023 and 2026, the others covering government services, health and payments, and each pilot fed real-world findings back into the Architecture and Reference Framework rather than working from it in isolation. Results are shared with the European Commission and the member states running national wallet pilots, so a business-wallet requirement discovered in a WE BUILD use case can end up reflected in a later ARF revision rather than staying a one-off workaround. Each work package publishes its methodology and test results openly, so an organisation outside the consortium can still learn from the interoperability findings rather than only from the specifications they later informed.
