Stani Kulechov, founder of Aave, stated that decentralized finance lending protocols require circuit breakers to manage potential oracle failures. He noted that without such mechanisms, errors in price data feeds could lead to incorrect automated liquidations, with consequences that might take years to resolve.
The proposal follows several incidents in 2026. On March 10, 2026, a configuration error resulted in $27 million in liquidations across 34 positions. In April 2026, an exploit involving the KelpDAO LayerZero bridge triggered a deposit run on Aave totaling $8.45 billion within 48 hours.
Aave is currently developing version V4, which features a hub-and-spoke architecture designed for improved risk management. This update includes modular risk isolation and the capability to freeze specific collateral lines to mitigate the spread of contagion during market volatility.
Kulechov emphasized that while immutable code is beneficial for trust, it limits the ability to respond to technical failures. He advocates for upgradeable code in critical areas like oracle management, though he acknowledged that implementing circuit breakers introduces new governance challenges regarding who controls these emergency tools.
