Swiss Bank Sygnum and Debifi Partner to Launch Bitcoin-Backed Loan Platform

Highlights:

• Swiss bank Sygnum and Debifi introduce MultiSYG, a secure lending platform backed by Bitcoin.
• Multi-signature wallets provide borrowers with shared custody and on-chain proof.
• Launching in 2026, Sygnum becomes a pioneer in regulated Bitcoin lending.

Swiss bank Sygnum and Debifi, a Bitcoin lending start-up, have announced a major collaboration to combine traditional banking with Bitcoin technology. Their new venture, called MultiSYG, provides an alternative, a new structure of Bitcoin-backed lending. The platform intends to provide borrowers with control over their digital assets and regulated access to bank lending. It will launch in the first half of 2026, marking a big step towards the intersection of traditional finance and decentralized systems.

MultiSYG enables customers to secure fiat loans in the form of Bitcoin as collateral. The collateral is in a three-out-of-five multi-signature wallet. This creates a situation where no one can transfer the assets without a common agreement. The wallet is managed by borrowers, Sygnum, and independent signers.

A Hybrid of Self-Sovereignty and Banking Trust

MultiSYG was developed by Sygnum Bank to address a long-standing problem of losing control over assets in crypto lending. Most banks require full custody of Bitcoin in order to loan clients, and this compels clients to trust custodians completely. However, MultiSYG changes that model. Borrowers can always have visibility of their Bitcoin holdings on-chain.

The founder and CEO of Debifi, Max Kei, said that clients should be provided with transparency. A Bitcoin loan must not entail blind faith in a custodian. Kei further added that the key structure of 3-of-5 provides bank-level service and on-chain verification to borrowers. This cryptographic confirmation and financial framework make MultiSYG unique.

Pascal Eberle, the lead of the Multi SYG initiative at Sygnum, pointed out that the service is both flexible and secure. The borrowers are able to take loans at affordable rates and authenticate their collateral using cryptography. Eberle explained that “MultiSyg introduces regulated lending to Bitcoin-native technology.” The platform reflects the notion of “not your keys, not your coins,” which is highly valued by Bitcoin advocates.

Strengthening Sygnum’s Bitcoin Ecosystem

The collaboration between Sygnum and Debifi is part of a broader institutional trend of Bitcoin-based finance. MultiSYG removes the rehypothecation risk of traditional systems so that assets remain untouched during loan terms. Such transparency becomes a crucial trust factor as the acceptance of Bitcoin among corporations increases.

Sygnum keeps growing its ecosystem of Bitcoin with various projects. Recently, it introduced institutional-grade, Solana-staking validator nodes from Abu Dhabi Global Market. This service enables eligible holders to get rewards while having control of their assets. The bank also launched the BTC Alpha Fund in collaboration with Starboard Digital, targeting an annual return of 8-10% through arbitrage strategies.

Moreover, Sygnum collaborated with CfC St. Moritz to assist the conference in creating a Bitcoin reserve. Bitcoin now constitutes 25% of the treasury of the event under the management of Sygnum. The move reinforces the image of Sygnum as a regulated institution, which is rooted in the Bitcoin economy.

MultiSYG fulfills this expanding portfolio by bridging the cryptographic transparency and regulated lending criteria. It also opens the door to flexible loan terms, competitive rates, and approved security of assets. The collaboration between Swiss bank Sygnum and Debifi indicates a maturity phase in the digital assets industry where security, regulation, and innovation meet.
