Cronos Halts Its Network After Tectonic Exploit as Loss Estimate Reaches $75 Million

Cronos stopped its blockchain on Sunday after an exploit hit Tectonic, the network’s largest lending protocol. An outside onchain estimate put the affected assets at roughly $75 million, turning what began inside one DeFi market into a chain-wide emergency.

The most important distinction is also the easiest one to miss: the $75 million figure was not a final number from Cronos or Tectonic. It came from onchain analysis cited by The Block, which reported that roughly $6 million was bridged to Ethereum before the halt while most of the assets tied to the position remained on Cronos.

Tectonic had not confirmed the amount or published a final root-cause report when this article was prepared.
