Compellio Brings EUDI Wallet To Banking

At GDC26 in Geneva, Compellio and Snappi showed how the EUDI Wallet can reshape KYC, payments and loan approvals in banking.

Luxembourg-based Compellio, alongside Greek digital bank Snappi, demonstrated live EUDI Wallet banking use cases at GDC26 in Geneva, showing how KYC, authentication, payment consent and loan approvals can go fully digital under eIDAS 2.0.

Following the demonstration, we sat down with Dr. Denis Avrilionis, Founder & CEO of Compellio, to unpack what the EUDI Wallet concretely changes for banks, how the Snappi partnership came together, and where Compellio’s roadmap is headed next — from core banking compliance to tokenised assets and Luxembourg’s Blockchain Laws.

Concretely, what does the EUDI Wallet change for a bank like Snappi?

For a bank like Snappi, the EUDI Wallet converts multi-day, friction-heavy customer journeys into an instant, cryptographically verified digital experience. It transforms five operational areas: instant onboarding (KYC/KYB) by replacing manual document uploads with automated, cryptographically backed verification of identity and Ultimate Beneficial Owners; 1-click account opening through pre-verified attributes such as proof of address, income, nationality and reusable IBAN attestations; phishing-resistant authentication that replaces passwords and SMS OTPs with passwordless Strong Customer Authentication secured by wallet keys; frictionless payment authorization by embedding digital consents directly into the wallet for Open Banking and account-to-account transactions; and legally binding contracting, automating remote loan, mortgage and contract approvals with built-in Qualified Electronic Signatures.

How did the partnership with Snappi come about?

The collaboration was forged under WE BUILD, one of the European Union’s Large-Scale Pilot initiatives testing real-world EUDI Wallet applications. At the GDC26 demonstration in Geneva, Compellio provided the core EUDI Wallet infrastructure and orchestration, with Snappi joining as the banking partner and IDnow as the Qualified Trust Service Provider, alongside an ecosystem coalition that includes Mastercard.

What is Compellio’s business model — who do you sell to, and how?

Compellio runs an enterprise software / B2B SaaS model. Its customers are regulated entities under eIDAS 2.0 — primarily banks and financial services, service providers in telecommunications, utilities and transport, and public sector organizations. The offering rests on two components: the EUDIW Backend Orchestrator & App, an interoperable middleware and security-hardened iOS/Android app for eIDAS 2.0 credential issuance, verification and lifecycle management; and a Tokenisation Gateway & Registry, a patented, multi-chain interoperability layer synchronizing on-chain digital assets with off-chain enterprise systems. Where other providers treat digital identity and asset tokenisation as separate silos, Compellio says it offers a single, cryptographically guaranteed flow covering both sides of a transaction — backed by a USPTO-granted patent for Digital Asset Exchange Coordination and contributions to standards such as IETF SATP and ERC-7943. Beyond traditional enterprise licensing, the company also offers turnkey deployment through Enterprise Cloud Marketplaces for one-click procurement in hybrid, on-premises or multi-cloud environments.

How do you see the regulatory landscape evolving with eIDAS 2.0 and the 2027 AML rules?

The convergence of eIDAS 2.0 and the 2027 EU Anti-Money Laundering Regulation shifts compliance from manual, document-heavy checks to real-time, cryptographic trust execution based on what Compellio calls a “reverse-GDPR” approach, giving users granular control over their data disclosures. The AMLR harmonizes Customer Due Diligence rules across the EU, with the EUDI Wallet acting as the runtime layer executing them automatically. Financial institutions will rely on Qualified Trust Service Providers and attribute issuers to instantly verify cross-border legal status, representation and address data, while auditability shifts from archiving static documents to managing cryptographic lifecycles with immutable, tamper-proof logs.

Why does Compellio matter for Luxembourg’s regulated and innovation ecosystem?

As a leading European business, fund and tech hub, Luxembourg sits at the intersection of strict cross-border regulatory demands — CSSF oversight, AMLR, MiCA, NIS2, eIDAS 2.0 — and structural digital modernization. Compellio positions three advantages for Luxembourg-based enterprises, financial institutions, telecom operators and public sector stakeholders: instant, frictionless KYC/KYB onboarding for cross-border retail and institutional clients; turnkey compliance for tokenisation, real-world assets and digital assets, including specialized roles such as Control Agents under Luxembourg’s Blockchain Laws; and a future-proof, multi-regulatory architecture unifying eIDAS 2.0, AMLR 2027, DAC8, PSD3 and MiCA into a single enterprise trust layer.

What’s next for Compellio after the Geneva demonstration?

Following GDC26, Compellio is pursuing commercial marketplace availability, expanding early-access pilot programs, and scaling beyond banking into telecommunications, energy, transport and public administration. The company frames its architecture as a multi-regulatory, cross-sectoral trust foundation combining sovereign identity with patented cross-chain interoperability. On the digital-asset side, combining the EUDI Wallet stack with its USPTO-patented cross-chain technology aims to enable instant KYC/AML compliance for tokenized real-world assets and deposit tokens — supporting Control Agent mechanisms under Luxembourg’s Blockchain IV Law, trusted investor registries verifying MiFID tiers, residency and accreditation at the token level, and traceable custody and settlement across chains. Compellio also points to its role shaping institutional Web3 infrastructure through co-authorship of the IETF Secure Asset Transfer Protocol, co-development of the ERC-7943 Universal Real-World Asset standard, joint research with MIT Connection Science, and participation in the EU’s first Blockchain Regulatory Sandbox.
