Cronos confirms $9.2M slipped away before Tectonic exploit rollback

Cronos’s post-mortem put the Tectonic exploit’s affected borrowing at $120.4 million, with 7.6% transferred off-network before validators intervened. Layer-1 blockchain Cronos said $9.19 million left its blockchain before validators halted the network during the Tectonic exploit, providing an official accounting of funds that were not reversed by its rollback. In Tuesday’s post-mortem report, Cronos said manipulated collateral values generated about $120.4 million in borrowing activity. Restoring the network to its pre-exploit state reversed about $111.2 million, leaving 7.6% of the affected funds outside of the network. The disclosure confirms the scale of the incident after earlier estimates placed the amount affected at about $75 million. It also puts the amount transferred off Cronos at $9.19 million, above the $8.3 million previously traced to Ethereum by blockchain data provider Bitquery.
