Sygnum Bank and Debifi will launch MultiSYG, a bank-backed, non-custodial platform that aims to change bitcoin loans for institutions and high-net-worth borrowers.
What is MultiSYG and when will it launch?
Sygnum Bank has partnered with lending startup Debifi to develop MultiSYG, a regulated product planned for H1 2026. The collaboration is described on the Sygnum Bank website, and the firms say the platform combines bank-grade terms with cryptographic proofs of ownership.
How is MultiSYG a non-custodial Bitcoin loans solution?
MultiSYG is built as a non custodial bitcoin loans structure: borrowers retain partial control because collateral sits in a shared wallet rather than with a single custodian. The setup uses a 5-party multi-signature wallet that requires 3 signatures to move collateral, letting borrowers verify funds onchain throughout the loan.

How does MultiSYG change custody for Bitcoin loans? In brief
MultiSYG embeds multi-party governance to reduce single-point-of-failure risks while preserving regulated bank services.
That hybrid aims to make secured lending acceptable to conservative counterparties without surrendering full custody. The concept aligns with the growing global trend for innovative custodial frameworks, such as those discussed in the OCC’s recent bank charter advancements.
Is this a bank backed Bitcoin loans product?
The offering is explicitly bank backed via Sygnum and targets institutional bitcoin lending desks and high net worth borrowers who demand legal separation of collateral. Institutional risk committees often prefer regulated custody arrangements; MultiSYG is positioned to meet those compliance needs. This is part of a wider phenomenon of institutional-grade bitcoin loans and reserves, seen as well in corporate treasury innovation for digital assets.
How do multi-sig Bitcoin wallets prevent rehypothecation?
Note: The 3-of-5 signing rule prevents unilateral collateral reuse and is designed to mitigate rehypothecation risk by separating signing authority from lending operations.
Separating signing authority from the lending counterparty aligns with standard audit trails and legal controls used by institutional lenders. These discussions about rehypothecation and institutional risk controls are also present in recent news about native bitcoin lending and on-chain privacy.
What do industry voices say?
“Borrowers shouldn’t need to trust a custodian blindly,” Debifi CEO Max Kei said in the announcement, and Pascal Eberle of Sygnum added that the approach combines holding keys with regulated banking terms. Industry coverage has highlighted those quotes and the model’s potential to raise institutional confidence in digital-asset lending.
