Ethena maintains reserve strength, extends bridge halt as rsETH risks remain without clarity
Concerns around cross-chain vulnerabilities have prompted Ethena to take precautionary action following the rsETH exploit. Despite confirming no direct impact, the protocol halted its LayerZero OFT bridge to limit potential exposure. An updated proof of reserves was released early, confirming that USDe remains fully backed by collateral exceeding supply.
Ethena Signals Caution Across DeFi with Extended Bridge Suspension
In an X post, Ethena stated it remains unaffected by the rsETH exploit tied to an instance of Aave v3 on Ethereum mainnet. Despite that, the protocol paused its LayerZero OFT bridge activity as a preventive measure. The decision came before a confirmed root cause analysis, signaling a risk-first approach.
The affected infrastructure involves cross-chain messaging powered by LayerZero. Ethena temporarily halted these bridge operations to reduce any potential exposure from unknown vulnerabilities. Initial expectations placed the pause at around six hours, though that timeline has now been extended.
Out of an abundance of caution we are temporarily pausing our LayerZero OFT bridges from Ethereum mainnet until the root cause of the rsETH incident has been identified.
We expect the pause to last ~6 hours and will provide updates on this temporary pause as we receive them.

Meanwhile, the protocol reiterated that its synthetic dollar, USDe, remains fully backed. Internal metrics show Ethena is overcollateralized, maintaining a backing ratio above 101%. Its updated figures place the ratio at approximately 101.20%, with total backing exceeding $5.63 billion against a supply of roughly 5.56 billion USDe.
Independent Audits Back Ethena Reserves as Protocol Stays on Alert
To reinforce transparency, Ethena released an updated proof of reserves earlier than scheduled. These attestations were verified by independent third parties, including Chainlink, Chaos Labs, LlamaRisk, and Harris & Trotter. Data confirms that collateral backing exceeds total supply, while all assets remain within approved parameters.
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.
We understand this is frustrating, but believe this is the prudent step to ensure safe cross-chain movement of your assets.

Reported figures show backing assets valued at over $5.64 billion, alongside a reserve fund exceeding $62 million. Ethena also confirmed its strategy remains delta-neutral, reducing directional exposure to market volatility.
Approved collateral assets include major cryptocurrencies such as BTC, ETH, and SOL, as well as stablecoins and yield-bearing tokens. While operations remain paused, Ethena acknowledged user frustration but emphasized caution as the priority.
Without a clear explanation behind the rsETH exploit, reopening bridge functionality could introduce unnecessary risk. The protocol stated it will resume operations only after gaining confidence in the system’s safety.
Attention now turns to the broader implications of the rsETH incident. Events like this often expose hidden dependencies across DeFi systems, particularly in cross-chain infrastructure. Even protocols without direct exposure can face indirect risks through shared integrations.
