CoW Protocol Launches on Polygon
CoW DAO is bringing its full suite of products - CoW Swap, CoW Protocol, and soon, CoW AMM - to Polygon. That means gasless, MEV-protected trading for one of the fastest-growing L2 ecosystems in DeFi.
No gas. No friction. No-brainer.
CoW Swap is now live on Polygon - and with it comes a different way to trade. If you're used to DEXs where you need to hold native tokens just to approve a swap, or where every transaction feels like a balancing act between gas costs and execution risk, CoW Swap offers a refreshing alternative.
It's a platform where the mechanics of trading melt quietly into the background. You don't need to worry about gas. You don't need to second-guess your slippage settings. You don't even need to bring POL. You just... trade. That's the whole idea: DeFi without the friction.
Polygon has built a reputation for being fast and cost-effective - but "cheap" doesn't mean "free." Most DEX users still pay gas to interact with contracts. And even if those fees are lower than on Ethereum mainnet, they still create a barrier - especially for smaller traders, new wallets, or those who simply don't want to juggle multiple tokens just to execute a simple swap.
CoW Swap removes that friction entirely. It covers the gas for you, bundles trades efficiently in the background, and ensures that you always get execution through the best available path. That means smoother onboarding for new users, more fluid trading for experienced ones, and a user experience that finally feels like it's keeping pace with the rest of the Polygon ecosystem.
This deployment also marks a milestone for CoW DAO itself. With Polygon now supported, CoW Swap becomes available across all major EVM environments: Ethereum, Gnosis Chain, Arbitrum, Base, Avalanche - and now Polygon. That's not just expansion for expansion's sake. It's part of a deliberate push to offer a gasless, MEV-protected, intent-based trading experience wherever serious DeFi users are active.
Polygon didn't just get another DEX. It got a different kind of trading infrastructure - one that quietly handles the complexity so you can get back to swapping.
Trade your Way
CoW Swap isn't just about speed and savings - it's about optionality. Most DEXs offer a single way to trade: you send a transaction and hope it gets executed close to the price you saw. That's fine for basic swaps, but as DeFi matures, so do the needs of its users. Traders want more control. Builders want more composability. And power users want tools that let them fine-tune execution without writing custom contracts.
CoW Swap brings all of that to Polygon - and then some. At its core, CoW Swap is designed to support multiple order types that go beyond the "buy now" model. Market orders are just the beginning. Users can also place limit orders, which let you define exactly what price you're willing to buy or sell at - and wait until the market moves in your favour. For longer-term execution, there's TWAP (Time-Weighted Average Price) support, which allows you to spread out larger trades over time to reduce market impact.
Then there's programmatic orders, which let you create logic-based conditions for a trade to execute - like only buying a token if your wallet hits a certain balance, or if a price crosses a certain threshold. These kinds of conditional orders open the door to more automated, composable DeFi strategies.
If you're looking for a true "set it and forget it" approach, Milkman orders let you place trades that execute only when market conditions are most favourable - delaying execution until the time is right.
And for developers or advanced users building on-chain workflows, CoW Hooks allow you to pair swaps with any on-chain action. Want to mint an NFT and swap tokens in a single, solver-routed transaction? Done. Want to claim staking rewards, rebalance your portfolio, and trade the excess? It's possible - and more efficient - through CoW Swap.
All of this functionality is now available on Polygon - meaning traders no longer have to choose between flexibility and usability. With CoW Swap, it's built-in. Polygon just got more powerful.
How CoW Swap Finds You a Better Trade - and Protects It
Most DEXs leave it up to you to find the best deal. CoW Swap flips that model completely.
At the heart of CoW Swap is a system built around user intent - not manual routing. When you submit a trade, you're not pushing it directly through a single liquidity pool or aggregator path. You're expressing what you want to do. From there, a competitive network of solvers steps in to figure out the most efficient way to make that happen - and compete to win your trade.
These solvers don't just route across AMMs like Uniswap, Sushiswap, or Curve. They also plug into other DEX aggregators like 1inch and Matcha, and they have access to private market makers and even their own internal inventory. If that wasn't enough, CoW Swap also unlocks something traditional DEXs can't replicate: Coincidence of Wants - where your trade gets directly matched with someone else's in the batch, allowing both of you to skip fees, slippage, and pools entirely.
What does this mean in practice? It means Polygon users now have access to a meta-aggregator - one that doesn't just search for liquidity, but intelligently optimises for it. The result is consistently better execution without you needing to tweak settings, split routes, or manage gas.
Every trade on CoW Swap is also shielded from MEV - the hidden tax that plagues most DEXs. In a typical DEX, your trade hits the public mempool the moment you sign it. MEV bots scan it, frontrun it, or sandwich it before it's confirmed - leaving you with worse prices and higher slippage, often without realising it.
CoW Swap is different. It batches trades off-chain, wraps them in protected intent, and routes them through a solver ecosystem where MEV extraction isn't just discouraged - it's structurally prevented. Combine that with MEV Blocker (a purpose-built RPC layer that blocks malicious mempool behaviour), and you get one of the most robust trade protection systems in DeFi.
On Polygon, this level of protection is now the default. No opt-in required. No wallet config. Just better outcomes, built in. With CoW Swap, you're not just getting a better price - you're getting a safer trade.
CoW Swap is For Builders, Too
CoW Swap isn't just a better place to trade - it's a foundation to build on. With CoW Protocol now deployed on Polygon, developers gain access to the same powerful infrastructure that underpins billions in volume across Ethereum and beyond. Whether you're building a wallet, designing a trading interface, or creating DeFi automations, CoW gives you access to a unified, intent-based layer that abstracts away the chaos of fragmented liquidity and unpredictable routing.
Instead of building around isolated pools or single sources of truth, you can plug directly into CoW Protocol's solver network and batch auction system, which handles execution intelligently - and fairly - on behalf of your users. No need to reinvent the wheel. No need to worry about sandwich attacks or gas fees. It's all handled by design.
And because CoW Protocol operates off-chain where it makes sense, while anchoring to the chain only when needed, it offers something rare in DeFi: scalability without compromise. Execution remains decentralized. Outcomes remain trustless. But the friction - technical and financial - is dramatically reduced.
This isn't just a set of APIs. It's infrastructure you can count on. Transparent. Efficient. Resilient.
