Company profile
researched Aug 2026DFNS develops wallet infrastructure that it positions as a "core banking platform for digital assets" and, in its documentation, as a secure operating system for blockchain finance. The platform provides unified wallet lifecycle management, transaction orchestration, granular access control and key management through an API, so that developers, fintechs and regulated institutions can create, embed and manage programmable wallets without building bespoke cryptographic infrastructure. Its key management approach is network-based rather than hardware-security-module or USB-device based: private keys are sharded and distributed across a peer-to-peer network using threshold/multi-party computation protocols, with the stated aim of removing single points of failure.
Product capabilities described by the company include multichain wallets across more than 100 networks, MPC signing, programmable transfer policies and quorums, admin roles, allowlists, notifications, WebAuthn/OTP authentication credentials, biometric authentication, a tokenization engine covering mint/transfer/redeem lifecycles, transaction routing, redundant RPC nodes, a governance engine, SWIFT connectivity and an on-premises deployment option. The company lists SOC 2, ISO 27001, ISO 27017 and ISO 27018 certifications; White Star Capital describes it as SOC 2 Type II certified.
Use cases marketed by DFNS span banking and custody, fintechs and neobanks, payments and PSPs, markets and trading, tokenization, and asset management. Named users and case studies include IBM (Digital Asset Haven), Apex Group, Keyrails, Coinsub, and earlier partners Nilos, Savingblocks, Kira, Powder and Mt Pelerin, a Swiss FINMA-regulated custody bank. Stripe engineering is also quoted on the company site.
Founding story
Nordic9 reports DFNS was founded in 2020 by Christopher Grilhault des Fontaines, Clarisse Hagege, Nore Rinnesjö-Eckerberg and Thibault de Saint-Sernin to address private key security, sharding wallet private keys and distributing the pieces across a peer-to-peer network. The company's seed announcement frames the founding premise as the poor state of private key management in web3, citing large historical losses from lost, stolen or exploited keys.
Business model
DFNS sells wallet and digital-asset infrastructure to businesses as a platform accessed through APIs and developer toolkits, with cloud and on-premises deployment options; the seed announcement frames the thesis as bringing wallets to a SaaS model ("Wallet-as-a-Service"). One customer reference notes a pricing structure tailored to payments companies. The sources do not disclose specific pricing or contract terms.
Sources do not state revenue figures or a detailed pricing model; the company describes a platform/API offering for institutional and fintech clients, with a customer noting pricing designed for payments companies.
Traction
The company's site reports more than $100B in client assets secured, over $10B in monthly transaction volume, 400+ fintech and institutional clients, 99.997% historical uptime since 2022, roughly 1% of global stablecoin payments settling through the platform, and a self-custodied euro-and-crypto neobank with 300,000+ users built on DFNS. At the time of the 2022 seed round it reported 100+ fintechs on its waitlist and partnerships with Nilos, Savingblocks, Kira, Powder and Mt Pelerin. Named later customers include IBM, Apex Group, Keyrails and Coinsub.
Latest developments
IBM launched Digital Asset Haven, its digital asset platform for banks, governments and enterprises, with DFNS as the core technology, including a tokenization engine, on-premises deployment, SWIFT connection and governance engine. The company also publishes case studies with Keyrails (stablecoin payments), Coinsub (payments) and Apex Group (tokenization).
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
DFNS presents itself as a leading wallet infrastructure provider, citing a 4.8/5 customer review score and comparing itself against Fireblocks, Taurus, Coinbase, BitGo and Utila across crypto custody, crypto wallet, tokenization and blockchain security categories. These comparative claims come from the company's own website and are not independently verified in the material reviewed.
Positioning rests on removing single points of failure via distributed, network-based key management rather than HSMs or hardware wallets; a developer-experience-focused API with granular permissions, policies and controls; claimed first introduction of biometric authentication for wallets (per an Apex Group executive); broad multichain coverage; enterprise security certifications; and the option of full on-premises deployment alongside cloud.
Technology
Network-based key management using threshold cryptography and multi-party computation, with private keys sharded and distributed across a peer-to-peer network to remove single points of failure. The platform exposes wallet creation, transaction signing and broadcasting APIs (e.g. EIP-1559 transactions), policy and quorum engines, WebAuthn/OTP and biometric authentication, multichain coverage of 100+ networks, redundant RPC nodes, a tokenization engine and optional full on-premises deployment. The company said at its seed round that it intended to create and open-source new threshold protocols and employ engineers and PhDs in cryptography.
Go-to-market
Developer-led and enterprise sales motion: public documentation, quickstart guides and API references, self-serve sign-up and "contact sales" paths, customer case studies, and distribution through large partners — most notably IBM, which selected DFNS as the core technology behind its Digital Asset Haven offering for banks, governments and enterprises.
Banks, neobanks, fintechs, payment service providers, trading and capital-markets firms, tokenization issuers, asset and wealth managers, custodians, enterprises and governments, as well as developers integrating wallets into applications.
Geography
Headquartered in Paris, France, serving clients described as spanning the world; the 2022 seed round proceeds were intended to scale operations in the EU and the US, and a customer settles flows across 100+ emerging markets on the platform.
History
Founded in 2020, DFNS announced a $7 million deal at the end of 2020 and closed a $13.5 million seed round led by White Star Capital in April 2022; White Star Capital dates its initial seed investment to October 2021. In January 2025, Bloomberg reported a $16 million Series A. The company subsequently expanded its positioning from wallet-as-a-service toward a broader core banking platform for digital assets, and IBM launched its Digital Asset Haven offering powered by DFNS.
