Bridged USDC Standard Now Available for All Orbit Chains

**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.

Arbitrum has launched new tools to help development teams migrate from Solana to Arbitrum while preserving their existing Rust codebase. **Key Benefits for Teams:** - Preserve existing Rust code and team expertise - Reduce rewrite overhead - Speed up planning, porting and validation processes - Lower time, cost, and hiring burden for testing Arbitrum strategies This initiative builds on Arbitrum's Stylus Sprint program, which recently funded 17 teams with 5M ARB to develop Rust applications and tooling. The program supports projects across AI, DeFi, gaming, and infrastructure, including oracle providers, developer tools, and security frameworks.

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.
