Aave is moving toward stricter collateral-listing standards after the April 18 rsETH exploit forced emergency freezes across Aave V3 deployments.
Aave service providers said the exploit was external to the protocol and traced it to the rsETH bridge setup. The incident still left Aave planning for bad-debt scenarios ranging from about $123.7 million to $230.1 million, depending on how losses are allocated.
rsETH Exploit Exposed $123.7M to $230.1M Risk
The exploit involved about 116,500 rsETH, worth roughly $292 million. Attackers abused the Kelp DAO rsETH LayerZero bridge and created a backing shortfall that allowed unbacked rsETH to circulate. Aave governance discussions said the risk reached the lending protocol through collateral.
Once rsETH lost its 1:1 backing, positions using it on Aave became undercollateralized. Aave then froze rsETH and wrsETH across V3 deployments to stop new exposure. The freeze came even though Aave’s own smart contracts, oracles and liquidation systems continued operating as designed.
Aave Weighs Hard LTV Caps for Bridge Risk
The policy response is now moving through governance. Aave contributors are discussing tier-gated loan-to-value limits, automatic tier degradation and stricter dependency reviews for staked and restaked assets. The proposed framework would require Aave to map the systems behind each collateral asset.
That includes bridges, oracles, smart contracts and external services that could affect whether the collateral remains fully backed. A related proposal says assets with bridge dependence, fragile oracle setups or deep rehypothecation chains should face hard LTV caps. Those limits would be harder to override when an asset carries structural risk.
Risk Stewards Cut Caps During Rulebook Debate
Aave has already tightened live risk parameters while the broader listing framework remains under discussion.
Risk stewards have been cutting supply and borrow caps across markets. They have also used soft freezes where needed and kept the ability to stop new exposure if collateral quality worsens.
Governance Has Not Finalized New Listing Rules
Aave has not yet finalized a binding collateral-listing rulebook after the rsETH incident. The current direction points toward stricter bridge reviews, faster automatic de-risking and tighter limits on wrapped or restaked collateral.
The next step is whether governance turns those proposals into formal rules for future asset listings.
