Echo Protocol pauses bridge after attacker mints ~1,000 eBTC (~$76M) on Monad, ECHO token plunges

Echo Protocol was exploited after an attacker minted roughly 1,000 unauthorized eBTC tokens on the protocol’s Monad deployment, representing about $76.7 million in value, according to initial on-chain reports ^{[1] [2]}.

The Echo team announced it has paused its bridge and temporarily suspended all cross-chain transactions while it investigates the incident, and blockchain security firms and on-chain analytics providers flagged the activity on-chain ^{[3] [2]}.

On-chain analysis cited by reporters indicated the attacker used a previously observed route involving Curvance and the breach was first publicly flagged by a crypto monitor; Echo’s native ECHO token also fell by double digits following the exploit, per coverage ^{[4] [2]}.

Investigations are ongoing and the protocol has not released a final remediation or recovery plan; observers continue to monitor on-chain activity and official updates from the Echo team ^{[3] [2]}.
