Cronos blockchain frozen after $75M Tectonic exploit

Cronos halted its blockchain after a $75M exploit on Tectonic, where an attacker manipulated TONIC prices. Most funds were trapped on-chain; $6M was bridged out. Crypto.com services were unaffected.

The Cronos blockchain was forced to halt operations after an attacker exploited the Tectonic lending protocol by manipulating the price of its TONIC governance token. Within just 20 minutes, the attacker artificially inflated TONIC’s price by nearly 100 times, then used the overvalued tokens as collateral to borrow against them, draining approximately $75 million from Tectonic. Validators on the Cronos network responded rapidly, freezing block production and trapping most of the stolen funds on-chain. Only about $6 million was reportedly bridged to Ethereum before the shutdown. This exploit followed a pattern similar to the Mango Markets incident in 2022, where thin liquidity enabled price manipulation. Tectonic advised users to avoid interacting with the protocol until safety is confirmed. Crypto.com assured users that its app and exchange were unaffected, and all user funds remained safe. The incident has renewed concerns about the security of decentralized finance protocols and their susceptibility to manipulation.
