According to online reports, digital asset bank Sygnum allows pledged Solana(SOL) as a loan collateral option, allowing institutional customers to gain liquidity while retaining pledged income. Sygnum said that pledged SOL loans can reduce the cost of capital compared to ordinary SOL mortgages, and part of the pledge income can be directly deducted from interest expenses. Sygnum adopts an independent on-chain hosting solution to complete pledge operations through APIs or account manager channels. In August last year, the bank issued a $50 million Bitcoin mortgage loan. SOL's current annualized pledge rate of return is approximately 5.7%. This is the first time that Sygnum has accepted pledged assets as collateral, reflecting the continued rise in institutional demand for liquidity management of crypto assets.
