Welcome to Superchain Sunday - our weekly newsletter! Every Sunday, we will provide you with the latest news and updates in the world of the Superchain.
The Superchain accounts for over 56.5% of all Layer 2 transactions and sees 20.5M daily transactions. The network boasts 830 Unique Apps, contributing to the Optimism Collective. It is estimated that 490.0 ETH will be contributed to the Optimism Collective in October. Data fetched from the Superchain Health Dashboard.
Vaults are officially live on OP Mainnet, marking a big step for DeFi on Optimism. The USDC Prime Vault by Gauntet, built on Morpho, introduces institutional-grade risk management with programmable lending features designed for both retail and enterprise users. It’s a move that strengthens the core DeFi infrastructure needed for sustainable, onchain financial systems.
This launch reflects Optimism’s broader mission to help companies build, test, and scale real financial products directly onchain. By combining deep liquidity with tools like Gauntlet’s Prime Vault, OP Mainnet is becoming the place where traditional finance meets composable onchain innovation. Explore the Vault here.
Optimism is positioning OP Mainnet as the starting point for enterprises looking to move onchain. It’s where companies can test, build, and scale financial products with real-world impact. OP Mainnet is more than infrastructure; it’s a pathway. Businesses can begin by integrating ‘Earn’ products such as vaults or lending markets, validate product-market fit using existing liquidity, and when ready, migrate to their own OP Stack chain for full customization and control. This flexible model helps enterprises grow from idea to independent network while staying within the Superchain ecosystem.
What makes OP Mainnet stand out is its speed, reliability, and cost efficiency. With 250ms transaction times through Flashblocks, 99.99% uptime, and a median transaction fee near zero, it delivers web2-like performance with web3 transparency. The recent integrations with Morpho, Gauntlet, and Utila show this vision in action, creating a complete enterprise yield stack that is secure, compliant, and operationally ready. OP Mainnet isn’t just another blockchain. It’s the foundation for the next generation of financial infrastructure. Read more here.
Bitcoin holders have long wanted a way to borrow against their BTC without giving up custody or wrapping it on another chain. With BitVM and BOB’s new Bitcoin Vaults Liquidation Engine, that’s finally becoming practical. This system introduces a smarter, faster, and more open approach to liquidations — making native BTC collateral usable across any chain without compromising Bitcoin’s core security guarantees.
The engine solves three of the biggest challenges in Bitcoin lending today: limited liquidators, all-or-nothing liquidations, and slow settlement times. It opens liquidations to anyone, supports partial repayments so borrowers aren’t wiped out entirely, and cuts settlement times down to minutes instead of days. It even enables atomic liquidations, where a loan can be repaid and collateral claimed in a single transaction. Altogether, this creates a new foundation for BTC-backed lending and borrowing that’s fast, efficient, and accessible to everyone. Learn more here
Polynomial has just taken a major leap for DeFi traders. For the first time, users can trade traditional markets like SPX, Gold, Oil, and Forex directly onchain — using crypto as collateral. Built on a novel oracle-based AMM powered by Pyth, Polynomial bridges the gap between DeFi and TradFi without sacrificing the principles of self-custody or transparency.
Traders can now access real markets, real hours, and real structure — all from their wallets. No funding rates, just rollover fees. No centralized intermediaries, just clean onchain execution. It’s a bold step toward a unified trading experience where crypto and traditional assets coexist seamlessly onchain. Start trading here.
The Optimism Budget Board has opened a new Request for Proposals for liquid staking of the Collective’s 21.5K ETH treasury. For the first time, the Collective is putting its ETH to work directly on OP Mainnet, turning idle assets into productive capital that strengthens the Superchain economy. Of the total, 5.4K ETH will remain in reserves, 9.6K ETH will go toward institutional staking on Ethereum Mainnet, and 6.4K ETH will be allocated to liquid staking protocols on OP Mainnet.
The goal is clear. Generate sustainable yield for the Collective, deepen liquidity, and drive more onchain activity. Each proposal will be scored using a Risk Adjusted Return Framework that compares Liquidity, Net Yield, and Ecosystem Benefit against overall risk. It’s a transparent and data-driven approach to treasury management that rewards protocols creating real value for the ecosystem. Learn more here.
The Superchain has grown to 34 different OP Chains, each with its flourishing Ecosystem. These are some extra stories to make your Sunday that much more Super.
