Starknet ecosystem DeFi protocol Nostra Finance stated in a post that there were serious issues with the price feed information of xSTRK and sSTRK, causing their value to increase by about 3 times between blocks 1256310 and 1256360 on March 24th (for example, xSTRK rose from $0.1793 to $0.5897). This increase in price feed data could lead to unnecessarily liquidating originally secure positions. Without available backup oracles to support these assets, Nostra is unable to fully prevent similar events from happening.

To protect the safety of user funds, Nostra has decided to immediately reduce the collateral cap for sSTRK and xSTRK to zero, no longer allowing them to be used for new collateral. It is recommended that sSTRK and xSTRK users withdraw their collateral as soon as possible. Nostra will continue to monitor the situation and update subsequent steps, re-evaluating the reliability and feasibility of the price feed information for xSTRK and sSTRK.
