Cronos Halts Blockchain After $75M Exploit on Tectonic Lending App
Cronos validators paused the network after a $75M exploit on Tectonic, stranding borrowed funds.

Cronos, the blockchain network, was halted by validators after an exploit on decentralized lending app Tectonic resulted in an estimated $75 million loss.
According to the report, the attacker inflated the price of Tectonic’s TONIC token by roughly 100 times, used the overvalued token as collateral to borrow other assets, and left most of those funds stuck when the network went offline.
How the exploit unfolded
The attack hinged on TONIC’s thin liquidity. By pushing the token’s price up sharply, the attacker could borrow far more against it than its real market value justified.
Validators paused the network to prevent further extraction, which also froze the attacker’s remaining holdings. The funds remain stranded as the community assesses next steps.
The incident adds to a series of DeFi exploits targeting lending protocols, where manipulated collateral prices can drain liquidity pools.
