Oracle provider Pragma classified six of 22 mainnet market and rate feeds as critical risk in a Sept. 18 assessment following a Sept. 17 borrowing exploit at Starknet lending protocol Nostra. According to NS3.AI, Pragma warned that a token price alone does not indicate whether collateral can be sold to repay a loan.

Nostra said it paused lending, borrowing, withdrawals, and liquidations after the exploit. Final losses, potential recoveries, and the status of subsequent withdrawals remained unconfirmed.
