OP Stack: Open-Source Blockchain Framework for Ethereum Scaling

**Optimism co-founder Ben Jones presented at Chainlink SmartCon**, highlighting the shift from institutional crypto testing to active building. **Key institutional adoption metrics:** - Stablecoins serving as cross-border payment rails - Real World Assets (RWAs) grew 14x to $30B over two years - ETFs transitioned from experimental to mainstream **Superchain dominance:** - Controls **70.7% of all L2 transaction fees** - Processes **9% of all crypto transactions** - Secures **$22B in onchain assets** - Powers 3 of top 4 L2s: Base, OP Mainnet, and Unichain Jones emphasized that regulatory clarity, widespread stablecoin adoption, and turnkey infrastructure have created optimal conditions for institutional onchain adoption. The **"institutional speedrun"** represents a pivotal moment where enterprises move beyond experimentation to production-scale blockchain implementation.

**OP Mainnet** has unveiled a comprehensive **enterprise yield stack** designed to help businesses build and scale onchain operations. The platform now features integrations with: - **@MorphoLabs** for lending markets - **@gauntlet_xyz** for risk management - **@utila_io** for enterprise-grade MPC wallet infrastructure **Key Benefits:** - Secure, high-performance blockspace - Institutional-grade yield products - Extremely low transaction costs - Deep liquidity and resilient infrastructure OP Mainnet serves as the **infrastructure backbone** for the Superchain, enabling companies to test and launch next-generation financial products. The platform combines efficiency with performance, setting new standards for onchain finance. The **USDC Prime Vault** is now live, offering enterprises direct access to institutional-grade yield opportunities on the network.
