Sygnum Bank bets on Bitcoin lending with multisign custody model

Sygnum Bank, a Swiss digital asset bank, has partnered with the Bitcoin-backed lending platform Debifi to introduce a novel multisignature lending product called MultiSYG. This product allows Sygnum clients to secure fiat loans using their Bitcoin as collateral while retaining shared control over that collateral through distributed key management. The setup requires three out of five key holders to authorize any transaction, which prevents the collateral from being rehypothecated and allows borrowers to track their assets on-chain. Sygnum highlighted that this model addresses growing investor demand for verifiable control over collateral, unlike traditional banks that require full custody. The product is scheduled to launch in the first half of 2026 for all Sygnum Bank customers. This move aligns with a broader resurgence in Bitcoin-backed lending activity seen across the industry.
