Swiss bank Sygnum will launch a Bitcoin mortgage platform controlled by a multi-signature wallet

ChainCatcher news, according to CoinDesk, Swiss digital asset bank Sygnum Bank has partnered with Bitcoin (BTC) lending startup Debifi to launch what is claimed to be the first bank-supported loan platform that does not require borrowers to give up full control of their Bitcoin.

The product is named MultiSYG and is scheduled to launch in the first half of 2026, targeting institutions and high-net-worth individuals who seek bank-grade loan services but are concerned about "re-hypothecation."
