$ARB Arbitrum Activates Elara Upgrade: Optional Compliance Filtering and Priority Fees for Dedicated Chains

Arbitrum activated the ArbOS 61 "Elara" upgrade on August 20, introducing a suite of key features to the ecosystem.

🔸 Optional Compliance Filtering: Disabled by default, this allows chain owners to configure compliance service providers (such as TRM Labs or Chainalysis) to filter transactions at the protocol level, enforced via simulation and on-chain safeguards.

🔸 Priority Fees: Disabled by default; chain owners must activate this feature via a precompiled function. Implementation on Arbitrum One still requires a separate DAO vote.

🔸 Expanded Stylus contract capacity and support for alternative data availability interfaces on dedicated chains.

👉 Elara is a strategic upgrade designed to meet the diverse needs of developers and institutions. Offering optional compliance tools makes Arbitrum more appealing to projects that must adhere to regulatory requirements, while priority fees allow dedicated chains to optimize their specific user experiences. This move demonstrates Arbitrum's flexibility and adaptability in competing against other rapidly growing Layer 2 networks.

💬 Do you think these new features will help Arbitrum maintain its position against Base and other Layer 2s?
