ParaSwap is a DEX aggregator, meaning the platform compares swaps from across the DEX universe. Choose a token pair and quantity, and ParaSwap shows you a rank-ordered list of DEXs that can support the trade, routing your trade to the best choice. ParaSwap also supports limit orders. The downside: ParaSwap blocks transactions from US IP addresses.
In a word: limit orders. Okay, two words. Other DEXs offer similar routing for swaps, choosing the most efficient swap out there. But many don’t support limit orders that let you choose an exact buy or sell price for your swap. The caveat: If you choose a limit price outside the trading range, your order might sit there until the end of time. Be sure to set a date for expiry.

People who want to use limit orders
Due to automated market makers (we discuss those in a bit), DEX pricing isn’t exactly a precise tool. If you’re an exacting type of trader. You can set the price you want with a limit order.
People who want peer-to-peer orders
Struck up a deal with someone to swap some crypto? Use Paraswap’s OTC feature to set up a peer-to-peer transaction that’s safe. Your funds stay in your wallet until the trade is executed for both parties.
CoW Swap

概述
Best For Peer-To-Peer Swaps
If you live in the ETH world, your ETH is more valuable than gold. CoW Swap lets you save your precious ETH by paying for any fees with the tokens you’re selling.
CoW Swaps does something different: The CoW protocol helps prevent frontrunning, which is a common occurrence that quietly costs traders money every day. Bots run around the internet looking for profitable trades that haven’t been validated yet. Then, these diabolical bots duplicate the trade with a higher gas fee, jumping ahead in line. The result: a sub-optimal trade for you — and profits for the bot. It’s called Maximal Extractable Value (MEV), and CoW prevents this from happening by executing peer-to-peer trades as well as using batch auctions.

Pros
No charge for failed transactions
No fee for limit orders
Peer-to-peer swaps
Prevents frontrunning
Cons
Limited blockchain support
适用于
Ethereum users: For now, CoW Swap is mostly an Ethereum thing. Gnosis is also supported, but Abritrum, Polygon, and Optimism users have to swap elsewhere. Mooo.
People who want to use limit orders: The feature is still in Beta (read: might be broken), but limit orders are live on CoW Swap. And they’re free. CoW Swap executes the limit order trade with a small spread, giving you an exact-price swap without fees.

Best For cross-Chain Swaps
OpenOcean is a DEX aggregator that helps you find the best swap rates on 20 supported blockchains. You can even do cross-blockchain swaps. (More on that later.)
If you need support for more blockchains, OpenOcean has you covered. In total, this DEX aggregator supports 20 blockchains ranging from Ethereum and layer 2 networks to Solana and Tron.
CoW stands for Coincidence of Wants, and it’s the key to low-cost swaps on CoW Swap. This clever protocol matches swaps without using liquidity pools whenever possible. If there isn’t anyone else who wants to swap the same tokens, then CoW Swap becomes a DEX aggregator, helping you find the best deal elsewhere. Nice. CoW Swap also supports limit orders, so you can just wait for the right price.
OpenOcean is reminiscent of UniSwap, with a clean interface that puts fine control over your trade just a click away. Where it differs from Uniswap is that OpenOcean is an aggregator. The app also supports cross-chain swaps. If you have tokens on Blockchain A, you can swap them for tokens on Blockchain B. That’s powerful stuff.
Swaps, limit orders, cross-chain swaps, leveraged perpetual swaps — what’s not to like? The main downside to using OpenOcean is that maybe it does too much. This isn’t the place to send your buddy from work who wants to learn how to DeFi. But if you’ve got a bit of crypto experience under your belt, OpenOcean gives you plenty of toys to play with and a suite of tools to maximize your trading profits.

OpenOcean lets you swap tokens like a superhero, leaping across blockchains. And you only have to wait a few minutes.
People who use limit orders

Traders on Cronos or Fantom blockchains
Ethereum and Abitrum DEX aggregators are easy to find. But for still-growing blockchains like Cronos (17 DEXs) or Fantom (16 DEXs), Firebird Finance can be a lifesaver, allowing you to find the best prices on swaps.
