# DeFi United Explained: The rsETH Recovery Plan > A backgrounder on the coordinated industry effort to restore the backing of KelpDAO's rsETH following the April 18 LayerZero bridge exploit. **Published by:** [ETH Daily](https://ethdaily.io/) **Published on:** 2026-04-30 **Categories:** defi-united, kelpdao, rseth, aave, layerzero, recovery, exploit, governance, defi, backgrounder **URL:** https://ethdaily.io/defi-united-explained ## Content DeFi United is a coordinated relief initiative led by Aave service providers to fully restore the backing of KelpDAO's rsETH liquid restaking token following the April 18, 2026 LayerZero bridge exploit. The effort spans token contributions from major Ethereum protocols and foundations, frozen-fund releases coordinated through L2 governance, and a multi-step technical plan to clear bad debt across Aave and Compound. This page summarizes the full timeline and the mechanics of the recovery.The ExploitOn April 18, 2026, at approximately 17:35 UTC, an attacker released 116,500 rsETH from KelpDAO's bridge contract on Ethereum mainnet without a corresponding burn on L2. The amount represented roughly 18% of the rsETH circulating supply and was valued at approximately $290 million at the time of the exploit. The attacker exploited a single point of failure in KelpDAO's 1-of-1 Decentralized Verifier Network (DVN), in which LayerZero Labs' DVN acted as the sole verifier. The funds were distributed across multiple wallets and used as collateral on Aave V3, Compound V3, and Euler, allowing the attacker to borrow an estimated $236 million in WETH. Aave's bad debt exposure across deployments was estimated to potentially exceed $170 million. LayerZero Labs subsequently attributed the attack to North Korea's Lazarus Group, identifying it as an RPC-poisoning attack against the DVN's verification path.Immediate ResponseAave froze its ETH and LST markets to contain bad debt accrual and prevent further withdrawals against compromised collateral. To give stranded aWETH lenders an exit, Fluid launched an aWETH redemption protocol and shortly after extended it to L2. On April 21, the Arbitrum Security Council froze 30,765.67 ETH connected to the exploiter on Arbitrum One. Of the moved funds, 75,700 ETH had already been swapped by the DPRK via THORChain before the freeze.The DeFi United Relief VehicleOn April 24, Aave service providers launched DeFi United, a deficit relief initiative to cover the estimated 118,000 ETH shortfall in rsETH backing. Initial pledges came from across the Ethereum ecosystem:EtherFi: 5,000 ETHLido: 2,500 ETHGolem: 1,000 ETHStani Kulechov (personal): 5,000 ETHMantle: a loan facility extended to the Aave DAOEthena, Ink Foundation, Tydro, and LayerZero also signaled participation without specifying initial amounts. Stani Kulechov publicly called on THORChain to contribute the roughly $450,000 in swap fees its protocol generated from the DPRK's exploit-related swaps.Aave Joins, Then The EFOn April 24, the Aave DAO formally offered to contribute 25,000 ETH to DeFi United, the single largest pledge to the initiative. Hours later, the Ethereum Foundation swapped aWETH for wstETH, a market-supportive position rather than a direct contribution but one that signaled foundational alignment with the recovery. By April 27, Aave founder Stani Kulechov confirmed that DeFi United had secured sufficient funds to fully restore rsETH's backing, with execution pending governance approvals and finalization of indicative agreements. Consensys and Joseph Lubin committed 30,000 ETH to the initiative the same day, and LayerZero formally contributed 5,000 ETH on April 28.Technical ImplementationOn April 28, Aave published the technical implementation plan for the recovery. The plan has two parallel tracks. First, ETH commitments are converted to rsETH in tranches and deposited into the bridge lockbox, allowing rsETH to return to its nominal 1.07 ETH exchange ratio and the bridge to resume operations. Second, governance proposals on Ethereum and Arbitrum will temporarily adjust rsETH's oracle price to enable controlled liquidations of the 107,000 rsETH still held as collateral by exploiter addresses across Aave and Compound. The recovered rsETH is then redeemed for ETH through Kelp and used to clear the deficits on both networks. Once the recovery completes, all temporary configuration changes are reverted and frozen markets are unfrozen, allowing lenders to withdraw. Aave noted that successful execution relies on the attacker not interfering with the liquidation sequence.Where It StandsDeFi United has secured commitments exceeding the 118,000 ETH shortfall. Aave has submitted a governance proposal to the Arbitrum DAO requesting release of the 30,765.67 ETH into a 2-of-3 Gnosis Safe controlled by Aave Labs, KelpDAO, and Certora. The full AIP governance process is estimated to take approximately 49 days. Detailed next steps for affected users are expected to be released by Aave in the coming days. This page will be updated as the recovery progresses.
