Swiss digital asset bank Sygnum has announced a partnership with bitcoin lending startup Debifi to introduce MultiSYG, a bitcoin-backed loan platform. Scheduled for launch in the first half of 2026, the platform is designed for institutions and high-net-worth individuals, offering bank-grade services while allowing borrowers to maintain control over their BTC. MultiSYG employs a multi-signature wallet system, requiring three signatures from Sygnum, the borrower, and independent signers for any collateral movement. This setup ensures that borrowers can verify their funds onchain and prevents the risk of rehypothecation, providing a secure and transparent lending environment.
