**Arbitrum Stylus introduces a new approach for businesses** to maintain performance-sensitive infrastructure offchain while verifying critical trust boundaries onchain. **Key implementation:** - Syndicate deployed SyndDB using Stylus to keep high-throughput systems offchain - Critical trust checkpoints remain verifiable onchain - Enables businesses to balance performance needs with transparency requirements This architecture addresses a common challenge: systems requiring high performance can operate offchain, while maintaining onchain verification for trust-critical operations. The approach offers flexibility beyond standard smart contracts. [Read the full technical details](http://blog.arbitrum.io/onchain-trust-for-offchain-workflows)

**Pleasing Market** is expanding digital gold infrastructure with **PGOLD**, a tokenized gold asset backed by physical reserves. **Key developments:** - $92M in gold now tokenized and available onchain - Built on Arbitrum for predictable execution and deep liquidity - Previously integrated Chainlink Data Streams for sub-second, verifiable gold price data The platform is making precious metal markets programmable, allowing users to trade and interact with gold-backed assets using blockchain infrastructure. This represents a growing trend of bringing traditional commodity markets onchain with transparent backing and real-time data feeds.

Oak Security has introduced **StylusPort**, a tool that allows developers to migrate Rust-based smart contracts from Solana to Arbitrum's EVM-compatible platform without rebuilding from scratch. **Key features:** - Migration guide for Solana applications - AI-powered tool to accelerate the porting process - Full EVM interoperability on Arbitrum **Benefits for developers:** - Faster deployment timelines - Reduced development costs - Simplified entry into EVM ecosystems The tool addresses a significant pain point for teams looking to expand beyond Solana's ecosystem. Previously, moving to EVM chains required complete application rewrites, creating barriers for cross-chain expansion. Oak Security is offering workshops and office hours to help developers learn the migration process. Teams interested in bringing their Solana applications to Arbitrum can sign up for guidance sessions.

**Programmable markets are revolutionizing trade settlement**, compressing what traditionally takes days into mere seconds. **The traditional gap**: When you buy or sell a stock on Monday, settlement typically occurs on Tuesday - a full day later. **The tokenized advantage**: In blockchain-based markets, value transfer and settlement happen in seconds, not days. **Key benefits**: - Dramatically reduced settlement time - Lower operational friction - Increased market efficiency Fintechs adopting this technology are positioned to gain competitive advantages in the evolving financial landscape.

El Dorado has introduced an **International VISA Card** that enables global USDT payments powered by Arbitrum. **Key features:** - Pay, send, and receive USDT worldwide - Low transaction costs with instant settlement - 24/7 accessibility - Eliminates traditional payment friction The card builds on El Dorado's existing platform, which serves **over 1 million users across 7+ countries in Latin America**. The company addresses regional challenges including inflation, high transfer costs, and limited USD access by converting stablecoins into practical financial tools. Users can save, send, convert, and now spend digital dollars through USDT on Arbitrum, all within a single application. This development represents a step toward making cryptocurrency-based payments more accessible for everyday transactions in markets where traditional banking infrastructure faces limitations.

**Ostium Labs has reached over $50 billion in total trading volume** on Arbitrum, marking a significant milestone for programmable markets. The platform enables trading across: - Stocks - Commodities - Forex - Crypto **Key features:** - Deep liquidity pools - Fast execution speeds - Built on Arbitrum's infrastructure This achievement demonstrates growing institutional adoption of blockchain-based trading infrastructure. Ostium's success follows a broader trend of traditional financial markets moving onchain, with platforms choosing Arbitrum for its reliability and execution capabilities.

Arbitrum has launched the **Fiet model**, a new approach to reserve-backed liquidity designed for institutional adoption in DeFi. **Key features include:** - Reserve-backed liquidity without requiring idle capital - Integration with existing custody and treasury systems - Onchain policy enforcement at execution level - Lower-cost, scalable market infrastructure Built by @usher_web3 on the Arbitrum Platform, Fiet addresses a critical challenge: **capital efficiency for institutions moving onchain**. The model allows DeFi protocols to integrate with traditional capital systems, creating a more practical pathway for institutional participation in the programmable economy. This development represents a bridge between traditional finance infrastructure and decentralized systems, potentially lowering barriers for institutional entry into onchain markets.

Arbitrum's new dynamic pricing system delivered significant results during a recent high-demand period across major networks. **Key Performance Metrics:** - Reduced fee spikes by up to 98% - Handled 2.4x more demand than competitors - Achieved 15% lower fees overall - Delivered ~17x less fee volatility The improvements came after the ArbOS Dia upgrade, which introduced a more sophisticated pricing model that tracks real network bottlenecks instead of relying on a single gas number. **Why It Matters:** Predictable fees enable businesses to forecast costs accurately, manage risk effectively, and scale operations reliably. This stability is crucial for programmable economies operating onchain. The system measures compute, storage, and history growth to create sustainable scaling without traditional surge pricing.
