Following the recent Tectonic exploit, the Cronos Foundation temporarily halted validators, effectively freezing the network, and restored the chain to its pre-exploit state.

Block production resumed on August 30 from block 90,896,189, effectively replacing more than 10,000 previously produced blocks. Cronos noted that RPC providers and other infrastructure services could require additional time to fully recover.

How Tatum responded

The rollback meant that previously processed blockchain data no longer matched the new canonical Cronos chain.

Our infrastructure team responded immediately.

Tatum restored access to Cronos and started replaying the affected blockchain data from block 90,896,188, bringing our infrastructure back in sync with the recovered network.

Tatum’s Cronos services are back online.

Throughput may remain temporarily limited while the remaining infrastructure completes synchronization, but developers can access Cronos through Tatum again.

Current status

We continue to monitor the network and complete the remaining synchronization in the background.

The Cronos incident was an exceptional network-level event. Our priority was simple: recover quickly, keep the data correct, and minimize disruption for developers building with Tatum.
