1. CoW Swap
Launched in 2021, CoW Swap was created to minimize MEV on Ethereum using batch auctions. CoW Swap was also created to protect users from sandwich attacks. Users of CoW Swap are involved in intent-based Swaps.
In intent based Swaps, solvers (or bots) try to outperform each other to give users the best Swap price. CoW Swap supports Swaps on both the Ethereum and Gnosis Chains.
CoW Swap is unique in that it first matches Swap orders internally to swap reserves before performing the Swap on AMMs. This ensures users are not subject to sandwich attacks. CoW Swap is also protected against front-running.
CoW Swap Pros & Cons
| Pros | Cons |
|---|---|
| Batch auctions reduce MEV and slippage | Execution depends on solver competition |
| Zero‑fee swaps with solver‑paid gas | Not ideal for very fast, high‑frequency trades |
| Strong protection against sandwich attacks | Limited network support (Ethereum, Gnosis) |
| Intent‑based trading ensures optimal pricing | Complex mechanism may confuse new users |
2. UniswapX
Like the other DEXs in the space, UniswapX focuses on reducing the amount of MEV on Ethereum. UniswapX employs a Dutch auction design to achieve this. UniswapX supports swaps on the Ethereum and all the major L2s.
UniswapX gives users the option to outsource Swaps to off-chain entities (fillers). This further protects users from MEV. To perform a Swap, UniswapX employs auction mechanisms to ensure Swap orders are performed at the best price.
UniswapX Pros & Cons
| Pros | Cons |
|---|---|
| Gasless swaps via fillers | Off‑chain fillers introduce trust assumptions |
| Dutch auctions reduce MEV | Execution quality varies by filler competition |
| Supports Ethereum + major L2s | Still early‑stage compared to Uniswap v3 |
| Strong protection against front‑running | Limited transparency in filler bidding |
3. 1inch Fusion
1inch Fusion provides MEV-protected swaps using resolver-based auctions. Its offering includes gas-free swaps. In this model, resolvers transact on behalf of users and cover gas costs. Changes in the resolver market conditions can impact swap costs.
1inch Fusion supports multiple EVM-compatible chains including Ethereum, BNB Chain, Polygon, Arbitrum and Optimism. Like other swap aggregators, 1inch Fusion’s main value proposition is to provide best price and least slippage swaps.
1inch Fusion Pros & Cons
| Pros | Cons |
|---|---|
| Gasless swaps with resolver‑paid fees | Resolver dependency may affect execution speed |
| Deep aggregated liquidity | Complex auction logic for beginners |
| Strong MEV protection via private execution | Fees vary based on resolver competition |
| Multi‑chain support (ETH, BNB, Polygon, etc.) | Requires trust in resolvers for optimal pricing |
4. Bebop
Bebop, launched in 2022, focuses primarily on swapping across multiple chains using MEV protection. It also offers swaps involving multiple tokens. Bebop lists a price for swaps and charges this price to the user.
Bebop provides swaps between tokens on Ethereum and Polygon. Like other projects, Bebop utilizes intent-based transactions and MEV protection to eliminate sandwich attacks.
Bebop Pros & Cons
| Pros | Cons |
|---|---|
| Guaranteed multi‑token pricing | Limited chain support (ETH, Polygon) |
| Intent‑based execution reduces MEV | Off‑chain intent resolution adds trust assumptions |
| Atomic swaps prevent sandwich attacks | Not ideal for simple single‑token swaps |
| Transparent quoted fees | Liquidity depends on Wintermute’s infrastructure |
5. Hashflow
Hashflow, launched in 2021, uses RFQs to remove slippage and connect users to market makers. Similar to other projects, RFQs are fully priced and therefore do not contain unexpected fees for users.
Users of Hashflow can swap across multiple chains including Ethereum, Avalanche, BNB Chain and Polygon. RFQs eliminate front running and ensure that swaps are executed at the price requested by the user.
Hashflow Pros & Cons
| Pros | Cons |
|---|---|
| RFQ quotes eliminate slippage | Market makers control pricing |
| Strong MEV protection via fixed quotes | Not fully decentralized execution |
| Multi‑chain support | Limited pool‑based liquidity |
| No hidden fees | Quotes may expire quickly in volatile markets |
6. Maverick Protocol
Maverick Protocol was launched in 2023. Although the core idea of Maverick is based on moving liquidity more effectively, Maverick is also a liquidity rotation protocol. Maverick is a swap and fees protocol similar to AMMs. Like AMMs, the fees charged by Maverick also vary by pool type.
Currently, Maverick supports the Ethereum, zkSync, and BNB Chain networks. Because Maverick Protocol reduces the opportunities for arbitrage and slippage, it reduces the need for MEV. As a result, the MEV bots that attack the protocol reduce.
Maverick Protocol Pros & Cons
| Pros | Cons |
|---|---|
| Dynamic concentrated liquidity | Complex pool types for new users |
| Reduces arbitrage‑driven MEV | Smaller ecosystem compared to Uniswap |
| Efficient execution with low slippage | Limited chain support (ETH, zkSync, BNB) |
| High capital efficiency | Requires active liquidity management |
7. Ambient Finance
Ambient Finance was launched in 2023. Similar to Maverick, Ambient builds on the concepts of unified liquidity and flexible trading. Fees charged by Ambient vary by pool and swap type. Ambient also supports the Ethereum network.
MEV is reduced thanks to the architecture of the pools which minimizes price impact and arbitrage. Like other AMMs, MEV is minimized. The architecture of Ambient focuses on stable coin trading and reduces front running and slippage.
Ambient Finance Pros & Cons
| Pros | Cons |
|---|---|
| Unified liquidity reduces MEV gaps | Only available on Ethereum |
| Efficient routing with low price impact | Smaller user base compared to major DEXs |
| Combines concentrated + ambient liquidity | Complex architecture for beginners |
| Stable execution with reduced slippage | Limited pool diversity |
8. Curve
Launched in 2020, Curve specializes in stablecoin swimming pools. The focus of Curve is the removal of slippage in swimming pools of correlated stable coins.
Slippage costs are very low in Curve. Active swimming pools on Curve charge a 0.04% fee. Cross-Chain Curve supports trading of stablecoins across multiple chains and reduces slippage.
Curve Pros & Cons
| Pros | Cons |
|---|---|
| Extremely low slippage for stablecoins | Not ideal for volatile asset trading |
| Tight‑peg pools reduce MEV | UI is complex for new users |
| Multi‑chain support | Fees vary by pool and can be confusing |
| Highly efficient AMM design | Requires deep liquidity for best results |
9. Balancer
Balancer launched in 2020. Its key innovation was introducing programmable liquidity with flexible boundaries. Like with other AMMs, users can add liquidity to pools to earn fees. Fees vary by pool. Balancer also employs smart routing to improve execution.
Its MEV protections eliminate some arbitrage opportunities. Balancer is available on Ethereum, Polygon, Arbitrum and Optimism.
Balancer Pros & Cons
| Pros | Cons |
|---|---|
| Customizable multi‑asset pools | Complex pool configuration |

Phoenix was launched in 2023, and is the first project to implement a centrally ordered book (CLOB) design to facilitate on-chain order matching. Order execution is fee market determined.
Phoenix utilizes a CLOB design to remove price manipulation that is inherent in AMMs. The CLOB design also prevents sandwich attacks.
Phoenix Pros & Cons
| Pros | Cons |
|---|---|
| Fully on‑chain CLOB | Only on Solana |
| Deterministic matching reduces MEV | Requires understanding of orderbooks |
| No AMM price manipulation | Less beginner‑friendly |

Conclusion
IN Conclusion Decentralized Exchanges (DEXs) that provide protection against MEV continue to gain traction. These DEXs offer benefits like reduced front-running, improved slippage, and increased execution certainty.
More specifically, the aforementioned DEXs utilize methods such as auctions and RFQs to execute trades. These methods, in turn, eliminate the need for order books, thereby reducing the complexity of the overall system.
As competition among centralized and decentralized market makers increases, the need for DEXs to integrate protective mechanisms against MEV will increase. Thus, DEXs will be able to provide a trading environment that improves upon centralized exchanges.
