Aave Restores Ether Borrowing Limits Across Six Networks After $230 Million Exploit Recovery

Aave has restored wrapped ether (WETH) loan-to-value ratios across six major networks, reversing emergency restrictions imposed after April's rsETH exploit that drained approximately $230 million in ETH from the decentralized lending protocol.

Market Context

The move marks a significant step toward normalization for DeFi markets, where WETH serves as one of the most critical collateral assets. During the crisis, Aave cut WETH LTV to 0% across affected networks—Ethereum Core, Ethereum Prime, Arbitrum, Base, Mantle, and Linea—as an emergency containment measure following a sophisticated bridging exploit targeting Kelp DAO's rsETH yield-bearing token.

Analysis

The restoration signals that immediate systemic risk has largely subsided after the April incident tied to a LayerZero bridging misconfiguration. Attackers minted roughly $292 million in unbacked rsETH and used it as collateral to drain approximately $230 million in ETH from Aave before large-scale liquidations and coordinated recoveries began. The DeFi United industry coalition is expected to cover the remaining shortfall of about 5,200 unrecovered rsETH tokens.

For traders and liquidity providers, reopening WETH borrowing capacityes constraints on leverage deployment and restores capital efficiency across multiple ecosystems. The protocol's decision to restore pre-incident LTVs—ranging from 80% to 84% depending on the network—indicates confidence that the exploit's cascading effects have been contained, even as legal disputes over frozen assets and liability questions remain unresolved.

Key Numbers

- $230 million in ETH drained from Aave during April's rsETH exploit

- $292 million in unbacked rsETH minted through LayerZero bridging misconfiguration

- 112,103 total unbacked rsETH tokens created in the attack

- 106,993 rsETH recovered (roughly 95% of total)

- 89,567 rsETH recovered through Aave liquidations specifically

- 17,426 rsETH recovered through Compound liquidations

- ~5,200 rsETH remaining shortfall to be covered by DeFi United coalition

What to Watch

Legal proceedings and liability determinations for the exploit remain ongoing, with questions about ultimate responsibility still unsettled. Traders should monitor whether restored WETH borrowing capacity translates into increased leverage demand across affected networks. The broader DeFi lending market's response to this recovery phase could set precedent for how protocols handle future systemic exploits involving cross-chain bridging vulnerabilities.

Bottom line: Aave's restoration of WETH collateral functionality represents a measured return to normal operations, but the incident underscores persistent risks in bridges and yield-bearing token architectures that the industry continues to grapple with.
