Arbitrum has integrated the Move programming language into its Stylus framework, expanding developer options beyond Solidity.
Key Development:
- Stylus now supports Rust, C, C++, and Move for EVM development
- Integration completed through collaboration with Rather Labs
- Enables enterprises to build new onchain primitives previously unavailable
What This Means: Developers can now choose from multiple programming languages when building on Arbitrum, removing traditional constraints of EVM development. Move joins the existing Stylus language support announced in September 2025.
Move has landed on Arbitrum Stylus brings Rust, C, C++ and now Move to the EVM - enabling enterprises to build entirely new onchain primitives This wasn鈥檛 possible without the collaborative effort from @rather_labs On Arbitrum, there are no boundaries to build onchain
It鈥檚 official, you can deploy Move Smart Contracts on @arbitrum! After months of work, we鈥檙e proud to introduce the Move-to-WASM compiler for Arbitrum鈥檚 Stylus Virtual Machine. This is great news for Move developers: you can now build in one of the largest and most well-funded
Arbitrum Moves Beyond Single Gas Fees to Multi-Dimensional Resource Pricing
Arbitrum is transitioning from traditional single-number gas fees to a dynamic pricing system that tracks actual network resource usage. The new approach measures three key bottlenecks: - **Compute** - Processing power consumption - **Storage** - Data storage requirements - **History growth** - Blockchain state expansion This shift aims to eliminate surge pricing while enabling sustainable scaling. The ArbOS Dia upgrade served as groundwork for this transition, introducing smoother fee structures on Arbitrum One. The dynamic pricing model will reflect real-time resource demand rather than applying blanket gas costs, allowing the network to scale more efficiently as usage patterns vary across different resource types.

Arbitrum Moves Beyond ArbOS Dia Toward Dynamic Pricing System
Arbitrum is evolving its fee structure beyond the recent ArbOS Dia upgrade. While ArbOS Dia introduced smoother gas prices and increased throughput on Arbitrum One, it was designed as groundwork for a more sophisticated approach. **Key Development:** - The platform is transitioning to **Dynamic Pricing**, where fees will reflect actual resource demand rather than fixed rates - This represents a shift from single-number pricing to demand-responsive costs **ArbOS Dia Foundation:** - Delivered smoother gas prices and predictable execution - Added mobile-grade authentication - Improved throughput for enterprise users The move toward dynamic pricing aims to create a more efficient resource allocation system on the network.

馃幆 Uniswap Launches First CCA Auction on Arbitrum with Huddle01

Uniswap has initiated its first Community Contribution Auction (CCA) on Arbitrum, partnering with Huddle01 for the inaugural event. **Key Details:** - First CCA auction now live on Arbitrum network - Huddle01 selected as launch partner - CCAs now automatically displayed in Uniswap Web App since February 2nd - All auction information consolidated in one interface The integration allows users to view live auctions, upcoming events, and track progress directly through the Uniswap platform. This marks a significant step in Uniswap's expansion of community-driven token distribution mechanisms on Layer 2 networks.
Arbitrum Enables ERC-8004 for Trustless AI Agent Infrastructure

**Arbitrum has activated ERC-8004**, bringing standardized infrastructure for AI agents to the network. The standard provides three core capabilities: - **Onchain identity** for AI agents - **Verifiable reputation** systems - **Cross-platform discovery** mechanisms Builders can now deploy trustless AI agents on Arbitrum, leveraging the network's liquidity and neutral platform. The standard allows agents to build transparent, verifiable performance records without centralized platforms. ERC-8004 enables community-driven validation and feedback systems, making agent capabilities discoverable and comparable across the network.
