Does Shell Finance Charge Any Fees?

When borrowers initiate a lending position, Shell Finance charges a one-time fee based on the interest rate and loan duration, meaning borrowers must pay the interest upfront. For instance, if Alice uses $BTC as collateral to borrow 1000 $sUSD with a loan term of one year and an interest rate of 12%, she will receive 1120 $sUSD. Of this amount, 1000 $sUSD is deposited into her account, and the remaining 120 $sUSD is collected by Shell Finance as prepaid interest. Alice must repay 1120 $sUSD to unlock and retrieve her collateralized $BTC upon repayment.
