Cronos Network Shutdown Triggers $75M Loss in Price-Exploit Hack

Cronos Network halted block production after a price-manipulation exploit hit Tectonic, its largest lending protocol, resulting in preliminary losses of around $75 million.

The incident centered on TONIC, Tectonic's thinly traded governance token, which an attacker reportedly pushed about 100-fold higher within roughly 20 minutes. This inflated valuation increased the token's borrowing power, allowing the attacker to use TONIC as collateral and withdraw other assets from lending pools.

Tectonic held $121.7 million in TVL and $82.7 million in active loans shortly before the price exploit. Only about $6 million was transferred to Ethereum before Cronos Network stopped producing blocks, leaving most affected assets stranded on Cronos.

Cronos Network confirmed the exploit and suspended block production while investigators examined the incident. Tectonic also instructed users not to interact with the protocol until operations are declared safe.
