Kelp to Resume rsETH Operations After $292 Million Breach

Key Insights

• Kelp will resume rsETH deposits and withdrawals weeks after its April 18 exploit.
• The protocol says rsETH has regained backing but is still planning migration to Chainlink CCIP.
• DeFi United is still going strong as LayerZero issues a public apology over its role in the incident.

Ethereum restaking protocol Kelp plans to resume rsETH operations weeks after a $292 million exploit forced withdrawal pauses across the protocol.

Kelp confirmed the restart Tuesday in a post on X after completing recovery coordination with Aave and other ecosystem partners.

Kelp Restarts rsETH Operations

According to Kelp, it will start refilling the stolen 117,132 rsETH into the LayerZero OFT Adapter from the Aave Recovery Guardian and Kelp Recovery Safe. This process is expected to take about two weeks.

However, rsETH operations will begin earlier once the first tranche of rsETH is sent to the LayerZero OFT Adapter. Kelp stated that it will unpause withdrawals tentatively within 24 hours.

All operations will become available once this is done, as the protocol will unpause all the contracts. Thus, deposits, redemptions, bridging, and claims will be available.

Unsurprisingly, the protocol noted that a comprehensive security upgrade has been implemented across all LayerZero bridging configurations, with BailSec auditing all changes.

These include increasing the number of independent attestors for verification to 4 and raising the block confirmations to 64 from 42. It has also deprecated all L2-to-L2 routes.

Despite relaunching on LayerZero, KelpDAO is still planning to migrate to ChainLink’s Cross-Chain Interoperability Protocol (CCIP). The protocol had announced this plan earlier in the month, noting that it would improve cross-chain bridging.

Crypto Projects Still United in rsETH Recovery Efforts as LayerZero Apologizes

The rsETH recovery has been possible only because of the outsized role of the lending protocol, Aave. The project proposed the initial backstop and recovery plan that led to the formation of DeFi United.

While the target has already been reached, donations and commitments continue to trickle in. Total donations are now at 137,717.27 ETH, worth almost $319 million.

Interestingly, Aave is also pushing to recover the 30,765.6 ETH linked to the rsETH exploit, which was frozen by the Arbitrum Security Council. While Arbitrum DAO wants to release the funds,  a recent lawsuit from an unrelated matter is seeking to restrain the transfer.

Aave filed an emergency motion to vacate the restraining notice. The court has now permitted an on-chain vote and transfer of the ETH from Arbitrum to Aave, while maintaining the restraining notice on the funds.

Meanwhile, LayerZero has issued a public apology for how it handled the exploit. The cross-chain infrastructure provider has faced criticisms for how its configuration enabled the exploit, but initially blamed KelpDAO for the incident.

However, it has now admitted that it made a mistake in allowing its DVN to serve as the 1/1 DVN for Kelp in such a high-value transaction. The apology appears to be coming too late, given that Kelp plans to migrate to CCIP, which requires at least 16 independent node operators before approving a cross-chain transaction.
