Cronos blockchain halts after $75M Tectonic exploit drains lending protocol

On August 30, 2026, the Cronos blockchain stopped block production after an attacker manipulated the price of Tectonic's TONIC token by about 100 times within 20 minutes. The attacker used the inflated token as collateral to borrow and drain $66M to $75M from Tectonic, the largest lending protocol on Cronos. Validators quickly froze the network, trapping around $60M of stolen funds on-chain and preventing further loss. The incident highlights risks in DeFi price oracles and the effectiveness of Cronos' small validator set in halting damage, though users interacting directly with Tectonic suffered losses while Crypto.com's centralized services remained unaffected.
