The cause of the processing delays affecting Tron, BNB, Optimism, and Arbitrum One in Reactor has been identified.
Chainalysis is applying a large update to cluster and address labels, which may result in temporary processing delays on some EVM networks. Most networks are completing processing, with Tron currently processing blocks approximately 30 minutes behind the tip.
We are actively monitoring these data processing activities and will provide further updates as available.
Next update: 18:00 UTC.
