Alternatives to traditional crypto exchanges: how DEXs work and which platforms to choose

Decentralized cryptocurrency exchanges (DEXs) are becoming an increasingly popular alternative to traditional trading platforms. Restrictions imposed by centralized exchanges are prompting users to look for other ways to exchange and trade digital assets. Meanwhile, modern DEXs can already offer familiar trading tools, high liquidity, and user-friendly interfaces.

Why users are switching to DEXs

Major centralized cryptocurrency exchanges periodically introduce restrictions for users from different countries. These measures may be driven by regulatory changes, sanctions compliance requirements, or trading platforms' internal policies. As a result, users may face limited access to certain services or lose access to a centralized exchange altogether.

Decentralized exchanges offer one possible alternative. To use most of these services, users only need to connect a cryptocurrency wallet. Creating an account and completing a standard registration process is generally unnecessary, as transactions are carried out through blockchain networks and smart contracts.

Unlike centralized platforms, DEXs do not require users to transfer their crypto assets to an exchange for custody. Users retain control over their wallets and private keys. Furthermore, decentralized exchanges are not subject to the same geographical restrictions as centralized trading platforms.

In the past, using DEXs required a certain level of technical knowledge. Users had to deal with clunky interfaces, software bugs, insufficient trading liquidity, and unpredictable transaction fees.

However, by 2026, the situation had changed significantly. Leading decentralized exchanges now offer functionality that is largely comparable to that of traditional centralized cryptocurrency exchanges. DEX users have access to price charts, various order types, position management tools, and trading with leverage*.

* Leverage is a trading tool that allows traders to open positions larger than their own available funds. For example, 10x leverage makes it possible to control a $1,000 position with $100 in collateral.

At the same time, decentralized exchanges are expanding their presence in the cryptocurrency market. By October 2026, their market share had reached approximately 23% of spot trading* and exceeded 12% in the perpetual futures* trading segment. In 2022, decentralized exchanges accounted for only around 4% of total trading volume.

* Spot trading involves buying and selling cryptocurrencies at current market prices, with direct ownership of the purchased asset, unlike trading derivatives.

* Futures are contracts whose value depends on the price of an underlying asset, such as Bitcoin. They allow traders to profit from price movements without owning the asset itself. Traditional futures have an expiration date, while perpetual futures do not.

What are decentralized exchanges (DEXs) and how do they work?

A DEX (Decentralized Exchange) is a blockchain-based protocol that enables users to exchange cryptocurrencies and other digital assets through smart contracts.

The main difference between a DEX and a centralized exchange (CEX) lies in how trading is organized and how assets are stored.

On a CEX, users typically register an account, complete identity verification, and deposit assets into accounts controlled by the trading platform. On most DEXs, users connect their own cryptocurrency wallets and interact with the protocol's smart contracts. In such cases, KYC* verification is generally not required.

* KYC (Know Your Customer) is a procedure used by financial services to identify and verify their customers. It typically involves submitting personal information and identity documents.

Until a swap is executed, the funds remain in the user's wallet, while access to the private keys stays exclusively with the wallet owner.

However, DEXs can differ considerably in how they operate. For example, Uniswap is primarily designed for token swaps using liquidity pools*. Hyperliquid, on the other hand, offers a full-featured trading terminal with an order book and tools for trading derivatives*.

* Liquidity pools are reserves of cryptocurrencies held in special smart contracts on decentralized exchanges. They let users swap tokens without finding another party willing to make the trade. Assets are deposited into these pools by liquidity providers — users who contribute their funds to facilitate swaps and receive a share of trading fees in return.

* Derivatives are financial instruments whose value depends on the price of another underlying asset, such as a cryptocurrency, stock, or gold. These instruments include futures, options, and perpetual contracts.

Decentralization does not mean that an exchange has no developers or company responsible for its development. The key distinction is that the exchange's underlying operation is not tied to its official website or a particular company.

Even if a decentralized exchange's official website becomes unavailable or access to it is restricted, users can still execute swaps through third-party applications or by interacting directly with its smart contracts. This is possible because DEX transactions take place on blockchains maintained by independent network nodes.

Nevertheless, restrictions may apply to individual DEX websites. For example, Uniswap Labs restricts access to its web interface for users from regions subject to US sanctions, including Crimea, as well as countries such as Iran, Cuba, and North Korea. However, the Uniswap protocol itself continues to operate, and users can interact with it through third-party services, such as the 1inch aggregator.

Main types of decentralized exchanges

Modern DEXs differ not only in the cryptocurrencies they support but also in how they execute trades. Some platforms are designed for quick token swaps, while others focus on active trading, including leveraged positions.

The market can broadly be divided into three main categories: automated market maker-based spot DEXs, perpetual futures exchanges, and liquidity aggregators.

Spot DEXs using Automated Market Makers (AMMs)

One of the most common forms of decentralized trading is based on AMM (Automated Market Maker)* technology.

* AMM (Automated Market Maker) is a trading mechanism used by decentralized exchanges that enables cryptocurrency swaps through liquidity pools without a traditional order book. Instead of matching buy and sell orders, an AMM uses mathematical algorithms to calculate exchange prices based on the quantities of assets available in a pool.

Consider the ETH/USDC trading pair. The corresponding liquidity pool contains Ethereum (ETH) and the USDC stablecoin. When a user buys ETH, they add USDC to the pool and receive a certain amount of ETH in return. Following the transaction, the amount of ETH in the pool decreases, while its price relative to USDC increases.

For users, this process is usually straightforward: select two tokens, enter the amount, and confirm the transaction in a cryptocurrency wallet.

Liquidity for these transactions is provided by market participants. They deposit their own assets into pools and receive a portion of the fees generated by swaps carried out using those funds.

Uniswap

Uniswap is one of the oldest and best-known AMM protocols and holds a leading position in the Ethereum ecosystem.

The platform accounts for more than 40% of the spot DEX market, with daily trading volume of approximately $2 billion. This exceeds the spot trading volumes of centralized exchanges such as Coinbase, Kraken, and Upbit, and is comparable to those of OKX and Bybit.

Uniswap supports digital asset swaps across 23 blockchain networks, including Solana.

One advantage of a decentralized exchange is that it does not charge an additional fee to use its interface. Users pay network transaction fees, also known as gas*, which are required to execute blockchain transactions.

* Gas refers to the fees paid to execute transactions and smart contract operations on a blockchain. The amount depends on the network's characteristics, the operation's complexity, and current blockchain congestion.

PancakeSwap

PancakeSwap gained widespread recognition through its operations on the BNB Chain blockchain. Over time, the DEX expanded its support to other blockchain networks.

In addition to standard token swaps, the platform offers various advanced trading tools. In particular, PancakeSwap supports limit orders*, TWAP orders*, and perpetual futures trading through Aster's infrastructure.

* Limit order is an instruction to buy or sell an asset at a specified price or better. The order is executed only when suitable market conditions are available.

* TWAP order (Time-Weighted Average Price) is a type of order that divides a large trade into several smaller transactions executed over a specified period. This helps reduce the impact of a large order on the market price.

Aerodrome

Aerodrome plays an important role in the Base network's decentralized trading infrastructure. This Layer 2 blockchain* was created by the US-based cryptocurrency exchange Coinbase.

* Layer 2 blockchain (L2) is an additional network built on top of a primary blockchain (Layer 1, or L1) to increase transaction processing speeds and reduce fees. These solutions process many operations off the main blockchain and then submit the necessary data or proofs to ensure security and verify results.

The platform uses two main types of liquidity pools: standard pools and concentrated liquidity pools* implemented through Slipstream technology.

* Concentrated liquidity pools are a type of liquidity pool in which users provide cryptocurrencies within specific price ranges rather than across all possible prices. For example, a liquidity provider may deposit ETH and USDC to facilitate swaps within a range of $3,000 to $3,500 per ETH. As long as the market price remains within this range, their assets can be used for swaps and generate trading fees. If the price moves outside the specified range, the position stops participating in swaps and earning trading fees until the price returns to the range or the position's parameters are adjusted.

The combination of these mechanisms helps maintain tight spreads* for major cryptocurrency assets available on the Base network.

* Spread is the difference between the best available buying price and the best available selling price of an asset. Generally, the narrower the spread, the more favorable the trading conditions.

In late October 2026, Aerodrome and Velodrome, a decentralized exchange operating on the Optimism network, announced a merger.

The merger created Aero, a unified cross-chain platform designed to operate across seven blockchain networks.

Raydium

Raydium is one of the largest decentralized exchanges in the Solana ecosystem and also serves as a liquidity provision protocol.

The platform supports both traditional liquidity pools and concentrated liquidity mechanisms.

Additional features include limit orders, the LaunchLab token launch platform, and perpetual futures trading through the external Orderly infrastructure.

Other well-known DEXs operating on Solana include Orca, PumpSwap, and Meteora.

Users can also compare swap conditions across different platforms through the Jupiter aggregator, which identifies suitable transaction routes.

Decentralized perpetual futures exchanges (Perp DEXs)

Decentralized exchanges focused on perpetual futures trading, commonly known as Perp DEXs, represent a separate segment of the market.

Perpetual futures are derivative instruments that allow traders to open positions without a predetermined contract expiration date. This segment is among the fastest-growing areas of decentralized trading.

User interest is also supported by trading incentive programs. Several projects are/ already running such campaigns or planning to reward participants in the future. These include Variational, Nado, Extended, and Arcus.

Another factor contributing to the development of Perp DEXs was the easing of the US Commodity Futures Trading Commission's (CFTC) stance on perpetual futures in May 2026.

Hyperliquid

Hyperliquid holds a leading position among decentralized perpetual futures exchanges in terms of both trading volume and open interest*.

* Open Interest is the total number or value of outstanding futures contracts that have not yet been closed or settled. This indicator helps assess activity in derivatives markets.

According to CoinGecko, in late October 2026, the platform accounted for more than 40% of the total perpetual futures trading volume on DEXs.

In September 2026 alone, Hyperliquid recorded $246 billion in trading volume. In terms of trading activity, this is comparable to centralized platforms such as Deribit, Bitget, and BingX.

In terms of interface and functionality, Hyperliquid closely resembles traditional cryptocurrency exchanges. Users have access to market and limit orders, stop-loss* orders, take-profit* orders, TWAP orders, and leveraged trading.

* Stop loss is a trading order designed to limit potential losses. It triggers the closing of a trading position when the price reaches a specified level.

* Take profit is a trading order designed to secure profits. It closes a trading position when the price reaches a predetermined target level.

Unlike AMM platforms, where cryptocurrency prices are determined algorithmically based on liquidity pool balances, Hyperliquid uses an order book. Asset prices are formed through interactions between buyers and sellers.

Order processing and execution take place directly on Hyperliquid's own Layer 1 blockchain.

The platform's trading instruments extend beyond cryptocurrencies. It also provides access to perpetual futures linked to traditional assets, including stocks, stock indices, currencies, and commodities.

Variational

Variational is a decentralized derivatives trading protocol built on the Arbitrum network.

Its architecture differs from traditional exchange models. Instead of a conventional order book, it uses RFQ (Request for Quote) technology, a system that requests price quotations.

When a user wants to open a position, the integrated liquidity provider, OLP, generates a trade quotation. The calculation takes into account liquidity available on major trading platforms.

The first application built on Variational was Omni. It enables trading in more than 500 perpetual contracts linked to cryptocurrencies and tokenized real-world assets (RWAs)*.

* RWA (Real-World Assets) are physical or traditional financial assets whose ownership rights or economic value are represented by digital tokens on a blockchain. Examples include real estate, bonds, stocks, and precious metals.

Among the platform's distinctive features are zero trading fees and a mechanism that lets users recover a portion of losses from unsuccessful trades.

Lighter

Lighter is a decentralized perpetual futures trading platform that operates on its own Ethereum-based Layer 2 (L2) network. The project is considered one of Hyperliquid's main competitors.

Lighter's advertised advantages include zero trading fees and cryptographic proofs that let users verify the correctness of trade execution.

Like Hyperliquid, Lighter uses an order book and offers tools familiar to users of centralized exchanges.

Other platforms in the Perp DEX category include Aster, GMX, edgeX, Extended, Derive, and dYdX.

DEX aggregators

In addition to individual decentralized exchanges, the cryptocurrency industry also has DEX aggregators — services that help users find the most favorable conditions for exchanging digital assets.

These platforms compare offers from numerous decentralized exchanges and determine the optimal swap route.

When necessary, a transaction can be split across multiple liquidity sources. This helps improve execution efficiency and reduce slippage*.

* Slippage is the difference between the expected price of a trade and the actual execution price. It can occur due to market price fluctuations or insufficient liquidity.

Among the best-known DEX aggregators are 1inch, which primarily operates within the Ethereum ecosystem, and Jupiter, which specializes in the Solana blockchain.

CoW Swap

CoW Swap takes a different approach to decentralized token swaps.

Its operation is based on a batch auction system. Instead of executing a swap immediately, users sign an intent to exchange specific tokens.

Special algorithms and system participants known as solvers then look for the most efficient way to execute the order.

The system first attempts to match the intentions of different users. For example, if one participant wants to sell a particular asset and another wants to buy it, their orders may be executed directly against each other.

This principle is known as Coincidence of Wants, which gives the service its name: CoW.

If no suitable matching orders are available, solvers access liquidity from external decentralized exchanges and determine the optimal swap route.

What you need to trade on a DEX

To start using most decentralized exchanges, you need a cryptocurrency wallet compatible with the relevant blockchain network.

Popular wallet solutions include MetaMask, Rabby, Trust Wallet, and Phantom.

Unlike centralized cryptocurrency exchanges, where fees are often deducted directly from a user's trading balance, blockchain transactions generally require separate network fees.

Therefore, users need to hold a small amount of the relevant network's native cryptocurrency in their wallets.

For example:

• ETH — for transactions on Ethereum;
• SOL — for transactions on Solana;
• BNB — for transactions on BNB Chain.

These funds are used to pay transaction processing fees.

On decentralized perpetual futures exchanges, settlements are often conducted using stablecoins such as USDC or USDT. Therefore, to open trading positions, users typically need to transfer the relevant assets from their cryptocurrency wallets to the platform's trading accounts.

At the same time, decentralized exchange architecture limits operators' ability to arbitrarily control or freeze users' assets as centralized exchanges can.

However, the degree of control users retain over their funds depends on the architecture of the particular decentralized exchange and the smart contracts it uses.

Security when using decentralized exchanges

Using DEXs involves independently managing cryptocurrency assets. This gives users greater control but also increases their responsibility for wallet security and transaction safety.

One of the most common threats is fraudulent websites that imitate the interfaces of well-known decentralized exchanges.

These websites may look almost identical to legitimate DEX platforms. If a user connects their wallet to a fraudulent website and approves a malicious transaction or grants permission to spend their tokens, they may lose their funds.

Therefore, verifying website addresses is particularly important.

Cryptocurrency service directories such as CoinMarketCap and CoinGecko can be used to find official resources. After verifying a decentralized exchange's website address, it is advisable to save it as a browser bookmark.

Accessing DEXs through random links or unverified search results can be risky, as they may include phishing* copies of popular platforms.

* Phishing is a type of online fraud in which attackers impersonate trusted organizations or services to trick users into revealing confidential information or granting access to their funds. Fraudsters may use fake websites, messages, and links to carry out such attacks.

Before swapping on a DEX, users should also consider the relevant blockchain network's characteristics, network transaction fees, potential slippage, and the specifics of the smart contract being used.
