Cowswap
Trade any ERC-20 token at the best available price — with MEV protection built in from the start, not bolted on after.

Why Cowswap
Most swaps on Ethereum cost you more than the quoted price — MEV bots extract value before your transaction settles. The Cowswap platform was built to stop that. Here is what makes it worth using:
Real MEV protection
Sandwich attacks and front-running are blocked by design. Solvers compete off-chain; your order lands on-chain only when the deal is final. You keep what you earn.
Peer-to-peer matching
When two traders want opposite sides of the same pair, Cowswap's protocol matches them directly. No AMM fees, no slippage from pool depth. It just works.
Aggregated liquidity
Uniswap v3, Curve, Balancer, and dozens more — all checked in every batch. You get one quote that reflects the entire on-chain market, not just one pool.
Gas abstraction
Fees are paid in the token you sell. You do not need ETH sitting around to cover EIP-1559 base fees. That alone removes a real friction point for new users.
How it works
The Cowswap settlement process is different from a typical AMM. Here is the short version — each step happens fast, usually within one Ethereum block.
You sign an off-chain order specifying what you want to sell, what you want to buy, and your minimum acceptable price. Nothing hits the blockchain yet.
A network of independent solvers — think of them as specialized routers — receive your order and race to find the best fill. They check Polygon-compatible routes, Gnosis Chain bridges, and Ethereum mainnet pools simultaneously.
Orders from multiple traders are bundled into one on-chain transaction. CoW (Coincidence of Wants) matches happen first; remaining volume goes to AMMs. One batch, lower overall gas.
If solvers find a price better than your limit, the difference flows back to you — not to the protocol. The team behind Cowswap calls this "Coincidence of Wants surplus."
Done. Your wallet shows the new balance. You can verify the settlement on Etherscan or via the Cowswap explorer. Got questions? See the full Q&A.
Key features
Limit orders
Set a target price and walk away. Your order stays open until the market hits your number or the expiry passes — no gas wasted on failed attempts.
TWAP orders
Dollar-cost average into any token over hours or days. The protocol splits your position into timed slices, each one filled at the best available rate during its window.
Token approval management
Partial approvals let you cap exposure. You decide the exact amount a contract can touch — a sensible default that most DEXs still do not offer.
Custom hooks
Power users can attach pre- and post-swap hooks to their orders. Combine a swap with a lending deposit or an NFT purchase in one atomic transaction.
Referral programme
Share a referral link and earn a cut of fees generated by the traders you bring in. The rewards code system is built directly into the swap UI — see the Refer button at the top.
Multi-network support
Trade on Ethereum mainnet and Gnosis Chain today. The solver framework that powers Cowswap is designed to extend — Forge-based testing has already validated the contracts on several testnets.
Open-source contracts
Every contract is verified on-chain and the source lives on GitHub. You can read exactly what happens to your tokens — no black boxes.

How do I start trading on Cowswap?
Connect any ERC-20 compatible wallet, select your sell and buy tokens, enter the amount, and confirm the swap. Cowswap handles the rest — routing, MEV protection, and settlement — without any extra steps from you.
What is Cowswap and how does it differ from other DEXs?
Cowswap is a meta-DEX aggregator built on CoW Protocol. Instead of routing directly to AMMs, it batches orders and settles them via a competitive solver network, often matching trades peer-to-peer and eliminating unnecessary gas costs from EIP-1559 transactions.
Is Cowswap safe and has it been audited?
Yes. The smart contracts have been reviewed by multiple independent security firms. The protocol has processed billions in volume since 2021 without a contract-level exploit. DeFi always carries risk — review the official docs and trade responsibly.
Can I use Cowswap if I am on Polygon or another L2?
Cowswap currently supports Ethereum mainnet and Gnosis Chain. The solver architecture is designed to extend to additional networks. For now, bridge your tokens to a supported chain and you are good to go.
Why should I choose Cowswap over a standard DEX aggregator?
Most aggregators still expose you to sandwich attacks. Cowswap's protocol uses batch auctions and Coincidence of Wants matching — solvers compete to give you the best price while front-running is structurally blocked. You get real protection, not just a promise.
What tokens and networks does Cowswap support?
Thousands of ERC-20 tokens on Ethereum mainnet and Gnosis Chain. Liquidity is sourced automatically from Uniswap, Curve, Balancer, and more. If a token has on-chain liquidity somewhere, Cowswap can usually find it. Learn more about decentralized exchanges on Wikipedia.
