Nostra是Starknet上的借贷协议，在确定了其价格提要的“关键问题”之后，已停止借用两个液体存放令牌

Starknet lending protocol Nostra has paused borrowing for two liquid staking tokens after encountering an issue with its price feeds, the decentralized finance (DeFi) protocol said.

分散的财务（DEFI）协议说，Starknet贷款方案Nostra在遇到价格提要的问题后暂停了两个液体存放令牌的借款。

The DeFi protocol encountered an issue with its price feeds on Friday, errors in which inflated the reported prices of xSTRK and sSTRK — two liquid staking derivatives of Starknet’s native STRK token — to approximately three times the tokens’ actual value, Nostra said in a post on the X platform.

诺斯特拉（Nostra）在X平台上的一篇文章中说，该DEFI协议在周五的价格提要上遇到了一个问题，在X平台上的一篇帖子中说，Xstrk和Sstrk的报道价格（Strk and Sstrk的报道价格是Starknet的两个液体桩衍生物）在X Platform上的一篇文章中说，这是代币实际价值的三倍。

“Such an inflated price feed could have caused unnecessary liquidations of otherwise safe positions, resulting in users with healthy positions getting liquidated,” Nostra said.

Nostra说：“这种夸大的价格饲料可能会导致不必要的清算，从而导致使用健康职位的用户被清算。”

In response, the DeFi protocol has disabled any further borrowing against xSTRK and sSTRK collateral deposits, Nostra said.

诺斯特拉说，作为回应，该规程已削弱了针对XSTRK和SSTRK抵押品的进一步借款。

Nostra has also recommended that users with existing xSTRK and sSTRK deposits withdraw the collateral immediately.

Nostra还建议使用现有XSTRK和SSTRK存款的用户立即撤回抵押品。

“Since we don’t have a secondary (fallback) oracle to support these assets, as none are available, we are unable to fully prevent similar events from occurring in the future,” Nostra added.

Nostra补充说：“由于我们没有次要（后备）甲骨文来支持这些资产，因为没有任何可用的资产，因此我们将将来完全防止类似的事件发生。”

“Our priority has always been and continues to be to keep existing user funds safe and with no fallback oracle, the risks outweigh the benefits,” it said.

它说：“我们的优先事项一直是并且继续是确保现有的用户资金安全，并且没有后备甲骨文，风险大于收益。”
