Arbitrum has activated the ArbOS 61 Elara upgrade, introducing optional protocol-level compliance filters, priority-fee support, and an alternative data-availability interface for dedicated chains, while also adjusting base-fee administration and expanding Stylus capacity on Arbitrum One. The governance-approved upgrade leaves compliance and priority-fee functions disabled on Arbitrum One and Nova. Chain owners, not ArbitrumDAO, must explicitly configure filters, choose providers like TRM Labs or Chainalysis, and define rules governing restricted addresses and transaction types. Dedicated chains can now adopt stricter transaction controls and optional tipping mechanisms, though documentation urges waiting at least 30 days before enabling filters. Further DAO votes will determine priority-fee use on Arbitrum One and any adjustments within the new fee range.
This update represents a notable development in the Crypto sector. Organizations and founders tracking this space should evaluate potential strategic and technical implications on their operations.
