Ethena, the issuer of the synthetic dollar USDe, has extended the temporary pause of its LayerZero OFT (Omnichain Fungible Token) bridge operations. The decision comes as a precautionary measure following the recent rsETH exploit, despite the protocol confirming it was not directly affected by the incident.
The initial suspension was announced on April 18, 2026, with an expected duration of approximately six hours. However, on April 19, Ethena announced an extension, stating, "As we have not yet received a satisfactory root cause analysis for the rsETH incident, we are extending the temporary pause on the OFT bridge." The protocol emphasized a "risk-first approach", prioritizing user safety over convenience, and committed to resuming operations only after gaining confidence in the system's security.
In parallel, Ethena released an updated proof of reserves ahead of schedule to reinforce transparency and maintain user confidence. Independent audits from firms including Chainlink, Chaos Labs, LlamaRisk, and Harris & Trotter verified that the USDe stablecoin remains fully backed. The protocol's internal metrics show a backing ratio of approximately 101.20%, with total collateral exceeding $5.63 billion against a USDe supply of roughly 5.56 billion. A separate reserve fund holds over $62 million.
Ethena's collateral basket includes major cryptocurrencies like Bitcoin (BTC), Ethereum (ETH), and Solana (SOL), alongside stablecoins and yield-bearing tokens. The protocol also confirmed its delta-neutral hedging strategy remains intact, mitigating directional market risk.
The incident highlights broader concerns about cross-chain vulnerabilities within DeFi. The rsETH exploit, which involved an instance of Aave v3 on the Ethereum mainnet, has prompted a sector-wide re-evaluation of dependencies and integration risks. Ethena's proactive suspension, even without direct exposure, signals a growing emphasis on security in interconnected DeFi ecosystems.
