Oracle service provider Pragma identified 6 out of 22 price feeds on the Starknet mainnet as critical risks during its assessment on September 18. The day before, lending protocol Nostra suffered a loss of approximately $3.5 million in assets due to manipulation of the NSTR price. Pragma stated that the affected response was composed of two sources, and if a minimum requirement of at least three sources had been enforced, the response would have been rejected. The anomaly originated from a manipulated on-chain pool. Additionally, 9 other price feeds in the same batch were flagged as high risk.
