Odaily News Nostra Finance, a DeFi protocol in the Starknet ecosystem, said in a statement that it had discovered serious issues with the price information of xSTRK and sSTRK, causing their value to rise by about 3 times between blocks 1256310 and 1256360 on March 24 (for example, xSTRK rose from $0.1793 to $0.5897). This price increase could cause previously safe positions to be liquidated unnecessarily.
Since there are no available backup oracles to support these assets, Nostra cannot completely prevent similar incidents from happening. In order to protect the safety of user funds, Nostra has decided to immediately reduce the collateral limit of sSTRK and xSTRK to zero, and no longer allow new collateral to be used. It is recommended that sSTRK and xSTRK users withdraw their collateral as soon as possible. Nostra will continue to monitor the situation and update the next steps to re-evaluate the reliability and feasibility of xSTRK and sSTRK price information.
