How scoring works →Summary
Tectonic is a decentralized lending protocol on Crypto.com's Cronos blockchain, forked from Compound and launched in December 2021. On August 30, 2026, an unidentified attacker exploited the protocol by manipulating the price of its thinly traded TONIC governance token approximately 100-fold in roughly 20 minutes, then borrowed an estimated $120.4 million in liquid assets against the inflated collateral. The incident forced Cronos validators to halt the entire blockchain and execute a controversial rollback of 10,961 blocks, reversing approximately $111.2 million in stolen funds while leaving $9.19 million permanently unrecovered. The exploit caused Tectonic's total value locked to collapse from approximately $121.7 million to roughly $3 million.
