PANews reported on May 16 that according to Beincrypto, digital asset bank Sygnum allows pledged Solana (SOL) as a loan collateral option, allowing institutional clients to retain staking income while obtaining liquidity. Sygnum said that staking SOL loans can reduce funding costs compared to ordinary SOL mortgages, and part of the staking income can be directly deducted from interest expenses. Sygnum uses an independent on-chain custody solution to complete the staking operation through API or account manager channels. In August last year, the bank issued a $50 million Bitcoin mortgage loan. The current annualized yield on SOL staking is about 5.7%. This is the first time Sygnum has accepted pledged assets as collateral, reflecting the continued increase in institutional demand for crypto asset liquidity management.
