Overview
- The attack, which unfolded Sunday, Aug. 30, 2026, saw the TONIC governance token surge roughly 100‑fold in about 20 minutes before an attacker deposited the inflated tokens as collateral to borrow large sums from Tectonic.
- Cronos validators paused block production minutes after detection, which froze most suspect funds on the chain and prevented about $60 million to $69 million from leaving Cronos while roughly $6 million was bridged to Ethereum.
- On‑chain researchers and trackers place the affected amount near $66 million to $75 million and show Tectonic’s total value locked collapsing from about $121.7 million to roughly $3 million after the incident.
- Tectonic accepted TONIC with a 20% collateral factor despite very low liquidity and relied on price feeds that apparently accepted the manipulated valuation, a design mix that enabled the pump‑and‑borrow attack.
- Neither Cronos nor Tectonic has released a postmortem, a restart timetable, or a compensation plan and Crypto.com’s centralized app and exchange have said customer deposits there were not affected.
