Arbitrum's Elara Upgrade Brings Transaction Blocking for Enterprise Clients

Arbitrum has released its latest network upgrade, ArbOS 61 'Elara', on August 20. This upgrade brings a new feature that allows operators of dedicated Arbitrum chains to block transactions from specific addresses.

This transaction-blocking feature is designed for enterprise clients who require enhanced control over their blockchain environments, particularly for compliance and risk management. The feature can be integrated with restricted address lists from third-party compliance providers like TRM Labs or Chainalysis.

Elara also introduces priority fee functionality, allowing transactions to be processed with different urgency levels, and improves data availability integration for dedicated chains.
