A bug in Nitro software caused a block divergence on Arbitrum Sepolia, leading to block production being halted as a precaution. This issue is affecting all Arbitrum Orbit rollups that depend on the same Nitro version.
Other Impacted networks:
Anime Sepolia
ApeChain Curtis
Mind Testnet
Edge Testnet
EARNM Testnet
Additional Arbitrum-based rollups may also be affected

The team is actively working on an infrastructure update and a new Nitro release to restore block production.
