Coincheck Group N.V. (NASDAQ: CNCK), a subsidiary of Monex Group, Inc., has signed a strategic partnership with DFNS, a Paris-based digital asset wallet and custody infrastructure provider, to deploy institutional-grade crypto custody services across Japan. The collaboration, announced August 31, 2026, targets Japanese financial institutions seeking secure, compliant digital asset infrastructure. Subject to regulatory approval and execution of definitive agreements, the partnership aims to enable Coincheck to offer custody services meeting institutional standards and local regulatory requirements.
- Parties Involved: Coincheck Group N.V., DFNS, and Monex Group, Inc.
- Service Focus: Digital asset wallet technology, custody infrastructure, and institutional-scale operations
- DFNS Platform Support: Over 100 blockchain networks with SaaS, hybrid, and on-premises deployment options
- Market Target: Japanese financial institutions and trust banks
DFNS‘s wallet-as-a-service platform integrates transaction lifecycle management, workflow orchestration, policy controls, key management, and third-party integrations into a unified system. The platform includes native hardware security module (HSM) support, addressing regulatory requirements for jurisdictional control over cryptographic keys, an increasingly critical requirement across regulated markets.
“Coincheck Group has forged trust with Japanese retail customers over the last decade and extending that into institutional services requires building a different class of custody infrastructure. DFNS’s wallet technology and institutional expertise enhance our existing capabilities.”
– Pascal St-Jean, CEO of Coincheck Group
Japan has developed one of the world’s most sophisticated digital asset regulatory frameworks, with trust banks serving as central players in institutional custody. Monex Group holds a majority stake in Coincheck and is using this partnership to expand its digital asset business beyond retail services into infrastructure solutions for corporate and institutional investors. The company intends to incorporate advanced global technologies to strengthen its financial infrastructure while focusing investment on growth sectors within the digital asset industry.
