Arbitrum: ArbOS Elara goes live with protocol updates - 20 Aug 2026

ArbOS Elara is live on the Arbitrum Platform, adding protocol-level compliance filtering, customizable priority fee support, and an alternative data API for dedicated blockchains. Arbitrum One also gains smarter base fee tuning and a fourfold increase in Stylus contract capacity, according to the ArbOS Elara announcement.For dedicated chains, these controls provide more tailored operating rules and data access. On Arbitrum One, improved fee tuning and greater Stylus capacity expand the room for application deployment and contract execution. Together, the changes broaden the platform's functionality across both dedicated-chain infrastructure and applications built on Arbitrum One.The release establishes that these features are available, but it does not demonstrate adoption by dedicated chains or developers. Their practical effect will depend on whether network participants use the new controls and capacity.ArbOS Elara is live on the Arbitrum Platform 🌞New for dedicated blockchains:✅ Protocol-level compliance filtering✅ Customizable priority fee support✅ Alternative data APINew on Arbitrum One:✅ Smarter base fee tuning✅ 4x capacity increase to Stylus contracts
