Sygnum Bank will launch in the first half of 2026 a Bitcoin-backed lending product using a multi-signature custody model called MultiSYG. The initiative combines Bitcoin-native multi-signature wallet technology with the services of a regulated bank, making it the first solution of this kind offered by a global financial institution.
The development of MultiSYG is carried out in partnership with Debifi, a non-custodial Bitcoin-backed lending platform. The product allows clients to maintain shared control of their collateral through a 3-of-5 key scheme, preventing the assets from being rehypothecated and offering greater security compared to full-custody models. Borrowers will be able to access fiat loans while keeping control over their collateral.
Sygnum’s MultiSYG loans provide competitive terms, flexibility in drawdowns and loan durations, as well as full regulated banking services. The combination of cryptographic autonomy with institutional backing allows clients to access the benefits of traditional banking without giving up the security and transparency of their digital assets.
Sygnum: Sovereignty, Security, and Compliance
The announcement coincided with the first anniversary of Sygnum’s office in Lugano and with the Plan B Forum, Switzerland’s leading Bitcoin event. According to Pascal Eberle, head of the initiative, MultiSYG integrates principles of asset sovereignty within a regulated framework, providing transparency and security without requiring blind trust in an external custodian.
The product was developed in response to the growing demand for Bitcoin-backed loans. In 2025, companies such as Riot Platforms, Cleanspark, Two Prime, FalconX, and Maple Finance secured credit lines backed by Bitcoin, arranged by institutions including Coinbase Prime and Cantor Fitzgerald. MultiSYG joins this trend, offering an alternative that combines user-side control with banking benefits.
At launch, MultiSYG will be available to all Sygnum Bank clients, regardless of jurisdiction, and will complement the bank’s existing credit and lending portfolio
