CoW DAO Unveils Seamless Cross-Chain Swaps

CoW DAO today announced a major leap in cross-chain trading with the official rollout of cross-chain swaps on CoW Swap, empowering DeFi users to execute seamless, MEV-protected transactions across multiple networks in a single step. Our first provider for this upgrade is Bungee, the Open Liquidity Marketplace behind $22B+ in volume since 2022. Already powering swaps and bridges inside top wallets and dApps used by hundreds of millions of onchain users, Bungee is the perfect launch partner for this next chapter of CoW Swap.

We love the multi-chain promise. Being able to seamlessly shift between vibrant communities across Ethereum, Gnosis Chain, Arbitrum, Base, Polygon, and Avalanche is the ultimate goal of DeFi. But let's be honest: navigating this multi-chain universe has often felt like a chore.

You find that perfect yield opportunity on Arbitrum, but your tokens are on Ethereum. What happens next? A frustrating dance of multiple steps: start a swap, wait for the transaction to confirm, pay gas fees on both sides, then finally start the bridge.

This fragmented experience isn't just inconvenient; it's often plagued by high transaction fees, frustrating delays, and significant security vulnerabilities that have led to billions in losses across the industry. Most existing solutions either require separate bridging and swapping steps, or to leave a tab open, or lack robust protection against hidden costs like MEV.

This friction has been a major bottleneck, even as the DeFi market continues its explosive growth, valued at USD 51.22 billion in 2025 and projected to reach USD 78.49 billion by 2030. Within this burgeoning ecosystem, the demand for seamless cross-chain solutions is immense, with cross-chain bridge transactions alone exceeding $250 billion annually in 2023. The need for a truly integrated, secure, and efficient cross-chain trading experience has never been clearer.

Well, we've heard you loud and clear. And today, we're thrilled to announce a game-changer that will redefine your cross-chain experience: CoW DAO’s cross-chain swaps are now live, powered by Bungee’s next-gen liquidity infrastructure.

Cross-Chain Trading Just Got a Whole Lot Smoother

Imagine this: you want to swap USDC on Ethereum for GNO on Gnosis Chain. Instead of two separate transactions and two different apps, you can now do it all in one single, seamless flow directly on CoW Swap. No extra steps. No extra apps. Just pure, unadulterated cross-chain trading convenience.

This isn't just an incremental update; it's a monumental leap in our multi-chain vision, positioning CoW Swap as the most seamless way to access liquidity across networks. We're tackling the core frustrations of cross-chain DeFi head-on, delivering a solution that's not only convenient but also inherently more secure and efficient.

“Cross-chain trading has always been one of the most painful experiences in DeFi. With this launch, we’re making it as easy as a single click. By combining bridging and swapping in one seamless flow, while retaining the user benefits CoW Swap is known for, we’re delivering on the multi-chain promise in a way that’s finally intuitive and secure.”

— Anna George, Co-Founder and CEO, CoW Protocol

What Makes CoW Protocol's Cross-chain Swaps Special?

While others might offer cross-chain solutions, CoW Swap brings its signature user-protective magic to the bridging experience. Here's why this launch is a cut above the rest:

All-in-One Convenience: This is the core promise. You can now swap and bridge in a single transaction, staying within the familiar CoW Swap interface. It saves you clicks, time, and precious brainpower that would otherwise be spent bridging manually.

Trusted Bridge Integrations: We're launching with Bungee as our first integrated bridge provider, with other potential partners in the pipeline. Launching with Bungee ensures that your cross-chain transfers are powered by reputable and secure infrastructure, mitigating the security risks often associated with bridges.

"We’re thrilled to partner with CoW Swap to bring gasless and MEV-protected swaps across chains to their users. This launch is a big step toward a chain-abstracted future where liquidity flows freely and users think in assets, not chains.

Bungee is proud to be the engine powering this experience behind the scenes, trusted by leading wallets, dApps, and now the largest DEX aggregator in DeFi."

– Vaibhav Chellani, Co-Founder & CEO, Bungee

Future-Ready Composability: This feature is built for the future of DeFi. It lays the groundwork for advanced workflows and composability, allowing for even more complex and efficient cross-chain strategies down the line. Think about pairing swaps with any on-chain action, like claiming staking rewards and rebalancing your portfolio in one go.

All the CoW Swap Benefits, Now Across Chains

You already know and love CoW Swap for its unparalleled trading advantages. Now, these benefits extend to your cross-chain trades, directly addressing the common issues in the space:

• Solver-Powered Pricing: Our network of competitive solvers constantly battles to find you the absolute best execution path and price for your trade, aggregating liquidity from every corner of DeFi. This means you get optimal prices, reducing the impact of slippage and ensuring efficiency.
• Gasless Trading: Forget about holding native chain tokens just to pay for gas. With CoW Swap, your gas fees are covered and can be paid directly in the sell token, making your cross-chain experience truly frictionless and more cost-effective.
• Surplus Capture: Our unique design ensures that any "surplus" found during trade execution is passed back to you, the user, not extracted by intermediaries. This directly counters the hidden costs often found in less optimized cross-chain routes.
• Unrivaled MEV Protection: This is our bread and butter. Maximal Extractable Value (MEV) is a hidden tax that costs traders billions. CoW Swap's architecture inherently protects you from sandwich attacks and front-running through:
• Uniform Clearing Prices: All trades for the same token pair within a batch clear at the same price, eliminating reordering exploits.
• Delegated Trade Execution: Professional solvers take on the price risk, guaranteeing you the price you signed for or better.
• Coincidence of Wants (CoWs): Our groundbreaking peer-to-peer matching mechanism allows trades to bypass external liquidity pools entirely, reducing fees, slippage, and providing inherent MEV protection. This unique feature is why we're called CoW DAO.

What's Next?

This is just the beginning of our cross-chain journey. We're already working on:

• More Bridge Providers: Integrating additional trusted bridge providers will give you even more choice and better routes.
• Automatic Best Route Aggregation: Soon, you won't even have to pick a bridge; CoW Swap will automatically find the best route and price for your cross-chain trade.
• Pure Bridging: Support for same-token cross-chain transfers.
• Advanced Workflows: Expanding composability with features like CoW Hooks for even more complex, automated DeFi strategies.

Trade Smarter, Across Chains

The DeFi landscape is constantly evolving, and CoW Protocol is committed to building the most user-protective products in the ecosystem. Cross-chain swaps are a testament to this commitment, removing friction and adding efficiency to your cross-chain trading.
