Swiss Bank Sygnum to Launch Bitcoin-Backed Loan Platform With Multi-Sig Wallet Control
Sygnum Bank and Debifi are launching MultiSYG, a Bitcoin-backed loan platform using multi-signature control.Summary
Swiss digital asset bank Sygnum Bank is partnering with non-custodial BTC lending startup Debifi to launch MultiSYG, a bank-backed loan platform set to open in the first half of 2026. This offering targets institutions and high-net-worth individuals who seek bank-grade loans but wish to avoid giving up full control of their Bitcoin, mitigating risks like rehypothecation seen in traditional finance. Borrowers will deposit BTC into a five-party controlled multi-signature wallet (Sygnum, the borrower, and independent signers), requiring three signatures for any collateral movement. This structure allows borrowers to maintain cryptographic proof of holdings and partial control over their assets while accessing regulated banking terms regarding pricing and flexibility.
