Key Takeaways:
- Aave V3 e-mode debt carries an 89.4% loan-to-value ratio
- The rsETH exploit drove governance to tighten listing standards
- USDe supply cap on MegaETH doubled to $800M after hitting 99.5%

Aave V3 e-mode nears 90% LTV as DeFi collateral stress mounts
Aave V3 e-mode debt reached an 89.4% loan-to-value ratio with a health factor near 1.05, Galaxy Research data shows, signaling thin liquidation buffers across blue-chip DeFi.
"The leverage density in e-mode creates a fragile equilibrium where even a 5 percent adverse price move can trigger cascading liquidations," Charles Yu, research analyst at Galaxy Research, said.
As of May 2026, Aave V3 carried $10.7 billion in loans against $17.37 billion in collateral across all markets. E-mode alone accounted for $6.3 billion in debt against $7.05 billion in collateral, with a debt-weighted health factor hovering just above the liquidation threshold of 1.0, per Galaxy data. The concentrated leverage sits in tightly correlated assets — ETH, liquid staking tokens and liquid restaking tokens — where price moves affect both sides of a position simultaneously.
The thin buffers matter because Aave's governance is still responding to the April KelpDAO exploit, which minted roughly 116,500 unbacked rsETH worth about $293 million. Attacker positions on Aave V3 Ethereum Core and Arbitrum were liquidated May 6, with 106,993 rsETH recovered across Aave and Compound out of roughly 112,103 unbacked on affected L2s, according to a LlamaRisk post on Aave's governance forum. The incident pushed Aave to signal tighter collateral and listing standards in early May.
USDe cap pressure tests governance response times
Separately, stablecoin supply dynamics added another layer of stress. USDe on Aave V3 MegaETH hit 99.5% of its 400 million supply cap, with one supplier providing more than $200 million in a single position. The Risk Steward process doubled the cap to $800 million after reserves refilled within three days, per a LlamaRisk governance post dated May 9. The episode illustrated how fast-filling caps can shift utilization and borrowing costs overnight, catching borrowers who rely on stablecoin liquidity for basis trades or leverage.
Cross-chain fragmentation compounds risk
Risk profiles vary materially by network. Ethereum mainnet offers deeper liquidity for liquidation unwinds, while L2 deployments on Arbitrum and MegaETH face thinner order books, bridge dependencies and fragmented oracle coverage. Aave's cross-chain architecture means governance decisions — cap changes, collateral re-ratings, freeze actions — must propagate across instances, creating latency that matters during stress events. Borrowers on L2s face a narrower set of unwind paths, often requiring bridge transactions that can congest or pause during incidents.
The rsETH recovery demonstrated the protocol's defenses working, but not without interim impairment risk. Of the roughly 112,103 unbacked rsETH on affected L2s, 106,993 was eventually recovered — a 95.4% recovery rate that still left residual bad debt for governance to address. Aave's subsequent push to overhaul listing standards, reported by CoinDesk on May 7, reflects recognition that collateral quality frameworks need to keep pace with the speed of cross-chain composability.
For borrowers, the takeaway is measurable: price a risk premium into every position, maintain health factor buffers that survive a 5 percent to 10 percent adverse move, and test unwind paths on the specific chain where capital sits. Blue-chip protocol code reduces smart contract risk but does not eliminate the market mechanics of liquidation — correlated collateral, thin liquidity and reactive governance all carry a cost.
