Sygnum Bank has teamed up with Bitcoin lending startup Debifi to introduce MultiSYG, a non-custodial crypto loan platform designed to give borrowers shared control over their Bitcoin (BTC) collateral. Scheduled for launch in the first half of 2026, the initiative targets institutional and high-net-worth clients seeking a secure, transparent, and regulated alternative to traditional crypto lending.

Redefining security in bitcoin-backed lending

Unlike conventional lending models that require borrowers to surrender full custody of their assets, MultiSYG uses a three-of-five multi-signature (multi-sig) structure involving Sygnum, the borrower, and independent signatories. This ensures no single party can move collateral unilaterally, reducing the risk of rehypothecation — the controversial practice of reusing borrower assets without consent.

The platform enables borrowers to verify their BTC collateral on-chain in real time, reinforcing accountability and eliminating the single points of failure that have undermined centralized lenders in past market cycles. Sygnum and Debifi describe MultiSYG as a “shared-control model” that merges on-chain transparency with institutional-grade oversight.

Bridging self-custody and regulated finance

Debifi CEO Max Kei said the partnership

“redefines crypto credit by giving borrowers verifiable control over their own assets.”

Pascal Eberle, who leads the MultiSYG project at Sygnum, added that the system combines

“the assurance of self-custody with the flexibility and compliance standards of regulated banking.”

Borrowers will have access to flexible drawdowns, competitive rates, and regulatory-grade loan terms, creating a bridge between decentralized finance (DeFi) and traditional capital markets.

The MultiSYG launch marks another milestone in Sygnum’s ongoing push to integrate decentralized infrastructure into regulated financial frameworks, setting a precedent for safer, user-controlled lending in the digital asset economy.

Separately, CfC St. Moritz, one of Europe’s leading digital asset conferences, has partnered with Sygnum Bank to establish a Bitcoin reserve, allocating 25% of its treasury to BTC as part of its long-term asset diversification strategy, a further nod to Bitcoin’s growing role as a reserve-grade digital asset.
