Aave founder: DeFi lending protocols need to introduce a circuit breaker mechanism to prevent oracle risks

According to Crypto Briefing, Aave founder Stani Kulechov stated at the DAS London conference that DeFi lending protocols need to introduce a "circuit breaker" mechanism, as the consequences of oracle failures could take years to resolve.

He pointed out that the over-reliance on immutable code systems lacks contingency plans. When oracle data deviates, the protocol may trigger liquidations based on incorrect prices, and the immutable nature can lead to irreparable failures. The circuit breaker mechanism draws from traditional markets' practice of halting trading during extreme conditions, allowing protocols to pause operations until the issue is identified.
