Introduction​

Cortex Protocol has transformed its complex trading capabilities through the integration of 0x's advanced swap technology. This integration enables Cortex users to execute trades with unprecedented efficiency across all supported networks, leveraging 0x's cutting-edge infrastructure to deliver the fastest, cheapest trading experience.

The 0x Advantage​

0x stands as a leading decentralized exchange infrastructure, supercharged with its v2 upgrade. The platform's state-of-the-art Argon Router delivers superior execution paths, consistently outperforming competitors like 1inch approximately 90% of the time across various trade sizes while maintaining remarkably low revert rates.

Optimal trade execution goes beyond quoted prices. In DeFi, the "best price" must account for gas costs, slippage, and other factors that impact the actual value users receive. 0x v2 optimizes for the best all-in price while ensuring swaps are fast and reliable—preventing wasted gas on failed trades or missed opportunities.

The power of 0x comes from its dual optimization approach:

• Multiplex routing splits trades across multiple liquidity sources
• Multihop execution identifies intermediate token steps to access deeper liquidity pools

This advanced routing system, powered by the Argon Router's state-of-the-art algorithm, delivers lightning-fast speed with the lowest revert rate in the industry, delivering the best routes available for Cortex Users.

Cortex's Implementation​

Cortex harnesses these capabilities to provide best-in-class trading experiences for users across all supported networks. The integration delivers:

• In-app swapping directly within the Cortex interface
• Optimal trade execution ensuring users receive the best all-in prices
• Multi-hop transactions enabling complex operations like swap + bridge + swap with minimal user intervention

Users can prompt the system with complex queries like "Swap my ETH on Ethereum for USDC on Base" and Cortex automatically structures the optimal multi-step transaction path, handling all the complexity behind the scenes.

By combining 0x's aggregation technology with Synapse infrastructure, Cortex creates the most seamless abstracted DeFi experience available today, allowing users to tap into external liquidity sources with unprecedented ease. Forget about which assets you have on which chains, buy the assets you want, powered by 0x layered with Cortex's smart routing.

Future Developments​

Cortex is committed to continuous improvement of the trading experience. Upcoming developments include:

• Expanding liquidity sources and routes with broader token and chain support
• Enhancing transaction abstraction to enable complex multi-hop operations with single-signature convenience

Our vision extends beyond just swapping We started with simple swap and bridge transactions, but this is just the beginning. Cortex is reimagining how everyone interacts with crypto, creating a new paradigm where complex on-chain actions are as simple as having a conversation.

The perfect foundation already exists Swaps and bridging both independently work, but they only own part of the user journey. Abstracting the execution and completely fufilling user intents saves time and money. Eventually Cortex will allow you to directly interact with your favorite DeFi protocols, like generating yield, and staking from within the platform. Cortex will evolve into the comprehensive AI-powered platform for analyzing and trading all of crypto.
