What Are DEX Aggregators? - Is Crypto Over

A decentralized exchange (DEX) is a cryptocurrency exchange that operates without the involvement of a central authority or third party. While DEXs offer a higher degree of security than centralized exchanges (CEXs), they often suffer from low liquidity resulting in slippage costs. This is where DEX Aggregators, also known as Liquidity Aggregators, come in. In this article, let’s deep dive in the Defi world and explore the magic of DEX Aggregator.

What are DEX Aggreators? - Is Crypto OVer

What is a DEX?

A DEX, or decentralized exchange, is a type of exchange that allows peer-to-peer transactions of cryptocurrencies and digital assets without the involvement of intermediaries like banks or brokers. Unlike centralized exchanges (CEXs), DEXs use smart contracts to facilitate trading directly between individuals while maintaining control of their own assets. DEXs can operate using different approaches like an on-chain order book, an off-chain order book, or an automated market maker approach.

DEXs offer greater security as users retain full control of their funds stored or traded on the exchange, reducing the risk of hacks or scams. However, this also means that the responsibility of securing one's own funds falls solely on the user, which can be a curse if not taken seriously.

Some popular DEXs include Uniswap and Sushiwap, both running on the Ethereum.

The Downside of DEXs

The major downside of DEXs is the lack of liquidity compared to centralized exchanges. Since DEXs rely on peer-to-peer transactions, the number of buyers and sellers for a particular cryptocurrency can be limited, which may result in higher spreads and lower trading volumes. This can make it difficult for traders to execute large orders and can result in less competitive pricing. This is where DEX aggregators come into play!

What is a DEX Aggregator?

A DEX Aggregator, also known as Liquidity Aggregator, is a financial protocol that enables traders to access multiple decentralized trading pools from a single platform. A DEX aggregator works with algorithms that consider various factors, such as pricing and liquidity, before selecting the best provider for a specific token type and enabling the swap between platforms. DEX aggregators aim to solve the lack of liquidity for smaller tokens on decentralized exchange.

Benefits of Using DEX Aggregators

DEX aggregators aim to provide a more efficient and cost-effective way of trading crypto tokens compared to using individual DEXs.

  • Providing single access point: DEX aggregators work by providing a single entry point of access to multiple DEXs simultaneously. This allows traders to view all available markets, order books, and prices across various blockchains from a single platform.

  • Finding better swap rates: The primary goal of a DEX aggregator is to provide traders with better swap rates than any single DEX can offer, as well as to do it as quickly as possible. DEX aggregators use algorithms that consider different factors such as liquidity, fees, and trading volume before selecting the best possible provider for a specific token type and allowing the swap between platforms.

  • Maximizing profits: DEX aggregators also enable traders to diversify their trading activity across multiple DEXs and take advantage of the different features that each DEX offers. This makes it much easier for users to find the best prices and maximize their profits.

  • Offering better security: Since DEXs operate without the involvement of a central authority or third party, users retain full control of their funds stored or traded on DEXs. This offers a higher degree of security than centralized exchanges (CEXs)

Top DEX Aggregators

Here are some of the top DEX aggregators:

1inch: 1inch is one of the most active DEX aggregators in 2021, with daily trading volumes averaging close to $300 million from 300,000+ active users [1][3]. The platform gives users access to over 120 liquidity sources on Ethereum, Binance, and Polygon networks, and the native token of the 1Inch DEX is also called 1 INCH.

Matcha: Developed by 0x Labs and built on the Ethereum network, Matcha is a DEX aggregator that allows users to have the best price of crypto assets from various liquidity sources [2]. The platform is relatively secure and uses the 0x v4 smart contracts audited by ConsenSys Diligence, a top blockchain company.

DefiLlama Meta-Aggregator: DefiLlama is a meta-aggregator that compiles liquidity from various DEXs such as Uniswap, SushiSwap, and Balancer, among others. The platform shows the total value locked (TVL) on each DEX, allowing users to choose the one with the highest liquidity.

OpenOcean: OpenOcean is another DEX aggregator that compiles several decentralized exchanges, including SushiSwap and Uniswap, to give users the best price of cryptocurrencies. The platform also supports multi-chain trading on Binance Smart Chain, Ethereum, and Polygon networks.

CoW Swap: CoW Swap is a decentralized exchange aggregator that allows users to find the best prices across various DEXs, including PancakeSwap and BakerySwap. The platform also supports cross-chain trading on Binance Smart Chain and Ethereum networks.

Other notable DEX aggregators include ParaSwap, Rango Exchange, and Firebird Finance


In conclusion, while DEXs offer a higher degree of security, they often suffer from low liquidity resulting in slippage costs. DEX Aggregators, on the other hand, provide a deeper pool of liquidity and allow traders to access multiple DEXs in a more efficient and cost-effective manner. Some of the top DEX aggregators in the market include 1 inch, Matcha, and ParaSwap.
