Arbitrum

**PYUSD has emerged as the leading tokenized asset by market cap growth on Arbitrum.** The stablecoin's expansion follows PayPal and Paxos leveraging Arbitrum's infrastructure. **Key factors driving adoption:** - Deep shared liquidity pools - Fast settlement times - Low transaction costs This follows a pattern seen with Spiko's tokenized products (EUTBL and USTBL), which reached $273M+ in total value locked on the platform. The growth demonstrates how platforms offering design flexibility, liquidity depth, and cost predictability attract tokenization projects.

**Hyve has integrated with Arbitrum** to build shared, verifiable data infrastructure for web3 applications. The platform transforms real-time data into a primitive that apps can access, promising: - Faster application performance - Reduced infrastructure overhead - Improved data accessibility Hyve will leverage **Arbitrum's speed, reliability, and deep liquidity** to develop its data economy infrastructure. This follows Arbitrum's recent integration with Pyth's institutional-grade data feeds in January. The move positions Arbitrum as a growing hub for data infrastructure projects in the L2 ecosystem.

Robinhood has launched its testnet for Robinhood Chain, a dedicated Layer 2 built on the Arbitrum platform. This follows the debut of Stock Tokens on Arbitrum One, which already offers EU users access to 2,000+ tokenized U.S. stocks and ETPs. **Key Features:** - Custom gas token support - Control over fees, throughput, and permissions - Fast confirmations with low costs **Phased Rollout:** - **Phase 1 (Testnet):** Developer onboarding, infrastructure testing, simulated asset flows - **Phase 2 (Mainnet):** Production network with broader access and service migration Robinhood is sponsoring Arbitrum's Open House program to support developers building on the new chain. The testnet allows contract deployment, bridging, and testing of tokenized asset flows without production risk. This represents a shift from traditional brokerage infrastructure to programmable onchain systems, where issuance, execution, and settlement can run continuously with fewer intermediaries.

Arbitrum is rolling out a **dynamic pricing system** that fundamentally changes how transaction costs are calculated on the network. **Key Changes:** - Moving away from single gas number to multi-dimensional pricing - Separate measurements for compute, storage, and history growth - Designed to eliminate surge pricing patterns - Tracks real network bottlenecks instead of aggregate demand **Why It Matters:** The new model aims to create more predictable and sustainable scaling by pricing different resource types independently. This approach could smooth out the fee spikes that have plagued L2s during high-traffic periods. The system represents a shift toward resource-specific pricing that better reflects actual network constraints.

Arbitrum One has implemented new gas targets and adjustment windows through its ArbOS Dia upgrade, addressing a critical need for enterprises: **predictable transaction costs during high-demand periods**. **Key improvements include:** - Reduced fee volatility under heavy network traffic - More reliable execution environments for institutional users - Enhanced throughput capacity - Mobile-grade authentication support The upgrade represents the first step toward **Dynamic Pricing**, a system where fees will reflect actual resource demand rather than fixed rates. This approach aims to provide transparency while maintaining network stability. For enterprises, the changes mean fewer unexpected cost spikes during peak usage, making Arbitrum One more suitable for production deployments that require consistent performance.

**Arbitrum Stylus has integrated the Move programming language**, joining its existing support for Rust, C, and C++. This expansion enables developers to build new onchain primitives using Move on the Ethereum Virtual Machine. **Key developments:** - Move language now compatible with EVM through Arbitrum Stylus - Integration completed through collaboration with Rather Labs - Developers can now choose from multiple programming languages (Rust, C, C++, Move) for building on Arbitrum **What this means:** The addition removes traditional boundaries for onchain development, giving enterprises and developers more flexibility in their choice of programming tools. Move, originally developed for blockchain applications, brings its safety features and resource-oriented programming model to Arbitrum's Layer 2 ecosystem. This technical advancement expands the options available for building decentralized applications on Arbitrum's scaling solution.

The inaugural Uniswap auction utilizing CCA (Continuous Combinatorial Auction) has launched on Arbitrum, with Huddle01 as the first project to use this mechanism. **Key Points:** - First CCA-based auction on Uniswap deployed on Arbitrum network - Huddle01 is pioneering this new token distribution method - CCA offers permissionless and customizable auction framework - Enables more transparent and onchain token distributions This marks a significant milestone for decentralized token launches on Arbitrum's L2 infrastructure.

**Arbitrum has activated ERC-8004**, a new standard that provides AI agents with onchain capabilities. **Key features now available:** - Onchain identity verification - Verifiable reputation systems - Cross-platform agent discovery The integration leverages Arbitrum's existing infrastructure—deep liquidity pools and credibly neutral platform—to support builders developing trustless AI agents. This follows similar deployment on Linea, expanding the standard across Ethereum's Layer 2 ecosystem. ERC-8004 enables portable reputation that transfers between platforms, allowing agents to build trust over time. The standard aims to establish an open agentic economy where AI agents can operate with verifiable credentials and accumulated reputation scores.

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. The platform's growth demonstrates how Arbitrum's infrastructure - including fast confirmations, deep liquidity, and predictable costs - enables decentralized perpetual exchanges to compete with centralized platforms. Variational has maintained an average of **22,000+ weekly users** since launch, leveraging Arbitrum's scaling capacity to deliver exchange-level performance for on-chain derivatives trading.
