Sveinn Valfells is an Icelandic entrepreneur, scientist, and early cryptocurrency participant known for co-founding Monerium, a company that issues regulated electronic money on blockchains. His career spans applied physics, biotechnology, telecommunications, and venture capital. Valfells' work in the blockchain space is influenced by his involvement in economic policy advocacy in Iceland following the 2008 financial crisis. ^[8]

Education

Valfells earned a Bachelor of Science (BS) in Applied Physics in 1990 from the Fu Foundation School of Engineering and Applied Science at Columbia University. He continued his studies in physics, obtaining a Doctor of Philosophy (Ph.D.) from Boston University in 1996. Following his doctorate, Valfells transitioned his focus to business and economics, earning a Master of Science (MS) in Management Science from Stanford University in 1998. ^{[1] [3]}​

Career

Valfells built his early career across technology, biotech, and venture investment, having founded or contributed to companies such as Atlas Genetics, deCode Genetics, Ingenuity Systems, Vodafone.is, Dimon Software, and the venture funds Arctic Ventures and IQ Capital. He became an early participant in the cryptocurrency space in 2011, helped organize the Bitcoin London and CoinSummit conferences, and co-authored several papers and reports on Bitcoin mining and blockchain economics. He also joined a non-partisan campaign following the 2008 financial crisis, which successfully advocated for rejecting taxpayer guarantees of failed bank deposits in Iceland’s 2011 referendum—a decision later upheld by a European court. In 2015, he co-founded Monerium, later serving as CEO and then executive chair, where he oversaw the company’s licensing milestones and early development in issuing regulated on-chain fiat. ^{[1] [2]}

Interviews

Stablecoin Opportunity

In this 51 Insights interview from November 2025, Valfells reflected on his path into crypto, beginning with his tech and cryptography background, his early discovery of Bitcoin in 2011, and involvement in the first London Bitcoin Conference, before discussing the 2015 founding of Monerium to enable regulated fiat on-chain. He outlined the company’s early regulatory efforts in Europe, contrasted European frameworks like MiCA with emerging U.S. legislation, and described Monerium’s plans for integrated payment flows and on-chain foreign exchange to support instant cross-border transactions. Valfells also addressed risks tied to USD dominance, factors slowing European adoption of stablecoins, and the broader market dynamics shaping uptake, while expressing optimism about expanding real-world applications. He closed by emphasizing that stablecoins function as regulated digital fiat and noting opportunities for smaller businesses to benefit from blockchain-based efficiencies. ^[5]

Monerium

In this July 2023 Epicenter interview, Valfells explained how Monerium was created to issue a fully regulated euro stablecoin, EURe, enabling users to move funds between their bank accounts and blockchain wallets through SEPA without relying on exchanges. He traced his path from studying physics and engineering at Stanford to exploring Bitcoin after the 2008 Icelandic financial crisis, eventually helping launch Monerium following years of commissioned research and regulatory review. Valfells highlighted the company’s strict compliance with European e-money rules, its business model of earning returns on safeguarded customer funds, and its aim to support Web3 builders by connecting traditional finance with decentralized applications. He also discussed plans to expand IBAN access, the role of regulated fiat-backed stablecoins in enabling tokenized real-world assets, and Monerium’s broader strategy to develop infrastructure that encourages adoption of compliant digital currencies. ^[4]

Future of Bitcoin

In this November 2023 Blockchain Insider panel, Valfells joined hosts Mauricio Magaldi and Catherine Gu alongside Jasper De Maere to discuss how the Lightning Network was shaping Bitcoin’s future. The conversation covered the network’s role as a layer 2 solution designed to improve Bitcoin’s speed and cost efficiency, recent developments such as Coinbase’s integration, and the ongoing divide between Bitcoin as a store of value and its use as a payment system. The panel explored emerging applications—including stablecoin activity and asset tokenization—while noting that Lightning transactions needed to remain competitive with other blockchain options and offer distinct advantages. Throughout the discussion, they highlighted rising transaction volumes, developer-driven innovation, hopes for stronger peer-to-peer adoption, and the potential for broader use in markets with limited traditional financial access. ^[6]
