Aave founder Stani Kulechov said at the DAS London conference that DeFi lending protocols need circuit breakers to manage oracle failures, according to a Crypto Briefing report cited by ChainCatcher. He warned that the consequences of a failure could take years to resolve.
Kulechov argued that systems relying too heavily on immutable code may lack an emergency response. If oracle data is wrong, a protocol could trigger liquidations at incorrect prices, while immutability could make the failure difficult to fix. He compared circuit breakers to pauses in traditional markets during extreme conditions: a protocol could suspend operations while the problem is investigated.
