Aethir said it detected and contained a malicious attack on ATH bridge contracts connecting Ethereum to other chains, with reported user losses staying below $90,000 despite a gross exploit estimated at over $400,000.
What Aethir Said About the ATH Bridge Hack
Aethir disclosed the incident on April 10, 2026, stating that all compromised contracts had been disconnected and the exploit had been contained. The project emphasized that the main ATH supply on Ethereum remained fully intact.

Blockchain security firm PeckShield independently flagged the exploit, estimating that over $400,000 was drained through the AethirOFTAdapter. PeckShield traced the stolen funds from BNB Chain to Tron via Symbiosis.
In a follow-up post, Aethir said that exchanges including Binance, Upbit, Bithumb and HTX quickly blacklisted the tracked wallets, providing immediate containment support across the industry.
Why Losses Below $90K Matter
Bridge exploits have historically ranked among the most damaging attack vectors in crypto, often resulting in losses of tens or hundreds of millions of dollars. Aethir's claim that user losses stayed below $90,000 would make this incident relatively minor by comparison.
The gap between PeckShield's over-$400,000 gross exploit estimate and Aethir's under-$90,000 user-loss figure has not been fully reconciled. Aethir had not published a detailed onchain breakdown explaining the difference at the time of writing.
ATH traded at $0.00597, down 1.35% over 24 hours, with a market cap near $109.7 million and 24-hour trading volume of roughly $13.7 million. The muted price reaction suggests markets viewed the containment as credible, though broader crypto sentiment sat at an Extreme Fear reading of 15 on the Fear and Greed Index. Recent incidents across the industry, from spot ETF-driven volatility to whale repositioning, have kept traders on edge heading into April.
What Users and the Market Will Watch Next
Aethir said it plans to release a full compensation and repayment plan next week, according to reporting from Cointelegraph. That commitment had not been published at the time of writing, making it a forward-looking pledge rather than a confirmed action.
Users who interacted with ATH bridge contracts across BNB Chain and other non-Ethereum chains will want confirmation on which wallets and transactions are eligible for recovery. A detailed postmortem, including the attacker wallet list and a reconciliation of the gross exploit versus net user losses, remains outstanding.
The speed of exchange coordination, with multiple major platforms blacklisting wallets within hours, mirrors the kind of rapid-response pattern the industry has developed after years of bridge exploits. Whether Aethir follows through on its compensation timeline will be the next meaningful signal for ATH holders. Broader security developments, including how protocols handle cross-chain asset flows, continue to shape market confidence.
