Haidrun is the infrastructure layer behind digital money — a Swedish company building private, compliant blockchain infrastructure for regulated institutions.
To be the infrastructure layer behind digital money — the reliable source from which value flows, securely and without end.
In Norse myth, Heiðrún is the goat whose mead flows without end. We took the name — and built the infrastructure for the continuous flow of digital money.
A fitting metaphor for what we do: a reliable, ceaseless flow of value, engineered with Swedish precision.
We set out to build a market-leading consensus mechanism and eliminate the energy cost that held back existing protocols.
Proprietary consensus with high throughput and native interoperability built directly into Layer 1 — no external systems required.
Production-ready v1.0.
Enhanced security and compliance from institutional feedback, an industry-standard REST API, a native SDK and EVM/wallet compatibility.
Deepening enterprise payments, treasury and real-world-asset capabilities.
Swedish engineering and integrity, applied to the infrastructure of money.
Infrastructure for money is not a place for hype. We build deliberately, for reliability that holds under load and over time.
Deterministic settlement, bank-grade security and compliance embedded in the core data model — precision by design.
We build for institutions that plan in decades, with infrastructure they own and control.
“Only the fastest is fast enough.”— Jonas Lundqvist, Founder & CEO
Haidrun is led by its two founders — operators who have founded, scaled and shipped enterprise-grade technology. Commercial and technical ownership sit side by side, backed by specialist partners and independent review.
Jonas founded Haidrun to build regulatory-ready infrastructure for digital money. A technology executive and entrepreneur with 35+ years across enterprise software, digital services and blockchain, he has founded, scaled and operated technology businesses throughout the Nordic market. He leads Haidrun’s commercial strategy and business development.
“Only the fastest is fast enough.”
Arnold owns Haidrun’s technology — platform architecture, roadmap and engineering. A deep-tech specialist across AI, blockchain and cybersecurity, he previously led Acando’s Center of Excellence for IoT, Big Data & AI and was program architect on one of H&M’s largest global transformations. Ph.D. in Biochemistry (Uppsala), Executive MBA (SSE), OSCP-certified.
A deliberately small core, supported by specialist partners and independent review — so the parts that carry regulatory and security weight never rest on a single pair of hands.
Security is checked by parties who did not build it: regular third-party penetration testing with findings tracked to remediation, and on-chain reserve attestation that can be verified without taking our word for it.
The network runs inside your perimeter on established infrastructure — multi-cloud across Oracle, Google, Azure and AWS, or on-premises — with key custody in FIPS 140-3 Level 3 hardware security modules.
Regulatory positioning and legal texts are reviewed by qualified counsel in each market before launch, against the frameworks we build for — MiCA, the GENIUS Act and the regimes set out on our regulatory map.
