Cronos halted its blockchain after an exploit on Tectonic, the network’s largest lending protocol.

Researchers estimate about $75 million in assets were affected after TONIC was inflated roughly 100 times in 20 minutes and used as collateral.

PeckShield put losses near $74 million. Only about $6 million was bridged to Ethereum before the halt.

Cronos later rolled back state and resumed block production from height 90896189. Crypto.com said its exchange and app were not compromised.
