d-fine is a European consulting firm built on quantitative analysis, modelling and technology, serving banks, insurers, asset managers and public bodies. Blockchain and digital assets are among its stated focus areas alongside AI, digital finance and digital sovereignty, and the firm has established a Stockholm base for the Nordics. Its relevance lies in what happens when established financial institutions take digital assets into production: the work quickly becomes risk modelling, valuation and regulatory reporting rather than a question of technology alone.
