Cronos Rollback: Is Your Transaction Gone? How to Check Your Balance

If you sent a transaction on the Cronos chain on August 30, 2026 between 12:38 and 14:33 UTC, it no longer exists today. Your balance stands at the value it held before that window. For most holders this is not expropriation but a complete reversal: whatever went out in that period was never debited either. There are cases, though, in which it does turn into real damage. This article shows you exactly which time window is affected, how to check your own transaction in a few minutes, and where the all-clear stops.

What happened on the Cronos chain on August 30

On September 8, 2026 the team behind Cronos published its post-mortem on the attack against the lending protocol Tectonic. A post-mortem is a project's after-the-fact investigation report into an incident. Only there do the hard numbers appear that had been missing until then.

The sequence, as the trade publication Cointelegraph relays it from the report: the attacker drove the price of the TONIC token up almost three hundred fold on thinly traded venues. A lending protocol lends out funds against posted collateral and values that collateral continuously through a price feed. That valuation is exactly where the attack landed. Against the artificially inflated collateral, the attacker borrowed $120.4 million across nine lending markets, spread over eleven transfers. The initial stake was around $5 million.
