Cronos blockchain halts after $75 million exploit on Tectonic lending protocol

The Cronos blockchain halted block production on Sunday after an attacker exploited Tectonic, its largest lending protocol, by artificially inflating the TONIC token price roughly 100-fold and using it as collateral to borrow approximately $75 million in assets. Validators paused the network, stranding most of the stolen funds.
