If you have funds sitting in a decentralised lending market, your risk is not decided by the interest rate but by the list of tokens the protocol accepts as collateral. On September 17, 2026, an attacker on Starknet exploited exactly that list and borrowed around 3.5 million US dollars from the Nostra Finance money market. The collateral was the protocol's own token NSTR, whose entire circulating market capitalisation stood between 550,000 and 590,000 US dollars at the time. The borrowed amount exceeded the market value of the posted collateral by more than five times.
