Sygnum Bank and Debifi Unveil MultiSYG, the First Bank-Backed Bitcoin Loan Platform With No Rehypothecation

According to CoinDesk, Sygnum Bank, the Swiss digital asset lender, has joined forces with Debifi, a BTC lending startup, to unveil a bank‑backed loan platform that allows borrowers to maintain custody of their Bitcoin. The arrangement is described as a pioneering model in crypto finance.

Dubbed MultiSYG, the product is slated for launch in the first half of 2026 and targets institutions and high-net-worth individuals seeking bank‑grade liquidity while avoiding full relinquishment of crypto control, addressing re-hypothecation concerns.

The collaboration underscores rising institutional interest in crypto‑collateralized lending and signals a shift toward custody‑aware terms, expanding access to traditional financing rails for digital assets without sacrificing asset control.
