About Rubicon

Rubicon is a decentralized order book exchange built on Optimism that offers efficient spot trading for a wide range of assets, aiming to replicate a CEX-like experience on-chain.

DEX Optimism DeFi

Rubicon is an open, on-chain trading platform that offers a fully decentralized, high-efficiency financial exchange built directly on Ethereum and leading Layer-2 solutions like Optimism, Arbitrum, and Base. By combining classic order book mechanics, automated market-making, and intent-based smart execution, Rubicon provides traders with superior liquidity and unmatched transparency.

With a focus on gasless, MEV-resistant, and non-custodial trading experiences, Rubicon bridges the gap between the performance of centralized exchanges and the ideals of decentralized finance (DeFi). Whether you're a trader seeking optimal execution or a liquidity provider maximizing yield, Rubicon is building the foundational rails for the world's last and most open financial exchange.

Rubicon revolutionizes DeFi trading by integrating three powerful trading layers into a single protocol: Rubicon Classic (on-chain order book), Rubicon Aquila (AMM liquidity pools), and Rubicon Gladius (intent-based trading). Unlike platforms like Uniswap and Curve that focus primarily on AMM models, Rubicon offers full order book capabilities, giving traders tighter spreads and greater price discovery opportunities.

At the core of Rubicon is Gladius, an intent-based off-chain order-matching engine that finalizes trades on-chain. This structure delivers a CEX-like user experience while maintaining complete decentralization. Competitors like dYdX and Perpetual Protocol offer similar hybrid models, but Rubicon stands apart by focusing entirely on ERC-20 spot markets with real-time, permissionless execution.

Rubicon Aquila brings the trusted AMM model of Uniswap V2 into Rubicon’s ecosystem, allowing passive liquidity providers to earn trading fees seamlessly. Meanwhile, Rubicon Classic offers an on-chain central limit order book (CLOB) where professional and algorithmic traders can operate with precision, minimizing slippage and maximizing control.

With integrations across Optimism, Base, and Arbitrum, Rubicon has built a truly multi-chain experience, designed to connect to the future of cross-chain DeFi liquidity. The open-source ethos of Rubicon ensures that anyone can access, contribute, and trade without barriers, setting a new standard for trustless financial marketplaces.

Rubicon offers a comprehensive suite of benefits and features designed to empower every type of DeFi participant:

Gasless and MEV-Free Trading: Dutch auction model protects users from frontrunning and minimizes gas expenses.
Superior Execution: Combines AMM, order book, and intent-based layers for optimal liquidity and pricing.
