Good to know

  • Loans run 1 to 30 days at a fixed rate, with no price-based liquidations.[2]
  • The collateral is the lender's only recourse: if it falls below the loan, the borrower may simply not repay.[1]
  • Lenders see an effective APY after the 10% fee: an offer at 16% shows 14.4%.[1]
  • Borrowers see an all-in rate: the offer APR × 1.25, pricing in the 25% upfront fee.[2]
