Arbitrum

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 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.

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.

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 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.

Arbitrum recorded $53M in net inflows over 24 hours, underscoring growing demand for neutral, deep liquidity in payment infrastructure. **Key metrics driving adoption:** - $7.8B+ stablecoin market cap on the network - $74B+ in 30-day transfer volume - 7.75M+ stablecoin holders Payment companies are leveraging Arbitrum's infrastructure for cross-border operations. Rise has processed $340M+ in USDC/USDT payouts with near-zero fees and ~250ms settlement times. El Dorado serves 1M+ users in Latin America with 4M+ P2P transfers. The platform recently demonstrated enterprise-grade capabilities by settling $3M in seconds with under $25 in total gas fees. These inflows reflect broader infrastructure maturation as enterprises adopt onchain rails for payments, neobanking, and stablecoin operations.

Arbitrum's NYC Open House online Buildathon runs from February 5-26, 2026, offering early-stage teams a three-week program to develop their ideas into MVPs. **Program Benefits:** - Technical workshops and go-to-market sessions - Mentorship from Arbitrum Foundation and Offchain Labs - Ecosystem support and guidance **Prizes and Opportunities:** - $30K in direct prizes - $30K in qualifying grants - Top 3 teams join the in-person NYC Founder House in March The program also includes a separate in-person event: the Arbitrum Open House on March 6, a selective 3-day founder program for teams ready to launch. Participants receive product feedback and technical guidance from ecosystem builders.

Arbitrum's **ArbOS 51 DIA upgrade** introduces a significant change to its gas pricing mechanism, moving from a single gas target to **six distinct gas targets**. **Key Changes:** - Gas processing capacity expanded from 7 Mgas/s to multiple tiers: **10/14/20/29/41/60 Mgas/s** - Designed to deliver **lower gas prices during network congestion** - Aims to provide smoother, more predictable execution environments for institutional users The upgrade focuses on improving throughput and gas price stability, particularly beneficial for enterprise applications requiring consistent performance. The multi-tier approach allows the network to scale more efficiently based on demand, rather than operating at a fixed capacity. This represents a technical evolution in how Arbitrum manages network resources and pricing during varying levels of activity.

Arbitrum Foundation is hosting an **in-person Open House in New York City** from March 6-8, 2026. This selective 3-day program targets founders ready to deploy on-chain applications. **What founders get:** - Direct collaboration with Arbitrum teams and ecosystem builders - Product feedback and technical guidance - Hands-on support for shipping projects This follows their online Buildathon that started January 29, which offered workshops, mentorship, and $60k in prizes. The NYC event is more exclusive and focused on teams closer to launch. Applications are open now at [luma.com/openhouse-newyork](https://luma.com/openhouse-newyork?utm_campaign=oh-nyc-founder-house&utm_content=sponsor-fh&utm_medium=social&utm_source=twitter).

Variational has become one of the leading perpetual trading platforms on Arbitrum, processing over **$136 billion in total trading volume** with **$1.09 billion in open interest** across hundreds of markets.
