Arbitrum Activates Elara Upgrade with Major Capacity Boost
Arbitrum has activated its ArbOS 61 Elara upgrade on August 20 at 17:00 UTC, bringing significant changes to both Arbitrum One and Nova. The update includes a major capacity boost for Stylus, a framework that lets developers write smart contracts in languages like Rust and C++ instead of just Solidity.
The compressed contract code size limit on Arbitrum One has jumped from 24 KB to 96 KB, a fourfold expansion that will allow developers to deploy more complex applications without running into size constraints. This is a key improvement for those working with Stylus.
The upgrade also introduces customizable priority fees for Orbit chain operators and ships an alternative data-availability interface for dedicated chains. In addition, base-fee administration has been modified across the network.
One of the most notable features of Elara is optional protocol-level transaction screening, designed exclusively for operators of dedicated Orbit chains who face regulatory obligations in their specific jurisdictions. However, this feature is disabled by default on Arbitrum One and Nova.
