According to CoinMeta, Wu said that they learned that the DEFI protocol’s Nostra account tweeted that on September 17th, the price of NSTR was manipulated, resulting in one account using NSTR as collateral to borrow approximately 3.5 million US dollars in ETH, STRK, USDC, USDT, WBTC, and DAIV1 on the StarkNet currency market. Currently, the Nostra currency market has been suspended, with borrowing, withdrawal, and settlement functions unavailable. The final losses and potential amounts that can be recovered have not yet been determined. The team is checking the impact on each asset and tracking the funds, and will work with relevant parties to recover the funds and release a verified investigation report. At the same time, users are reminded to be wary of impostors.
