Decentralized exchanges, commonly known as DEXs, represent a fundamental shift in how people trade cryptocurrencies. Instead of relying on a central company to hold funds and process trades, DEXs allow users to trade directly from their own wallets using blockchain technology. This approach prioritizes self-custody, transparency, and open access—but it also comes with a learning curve.
Let’s break down what a DEX is, how it works, and why it plays such an important role in the crypto ecosystem.

Understanding the Role of Exchanges in Crypto
Since the early days of Bitcoin, exchanges have been essential for matching buyers and sellers and helping the market agree on prices. Traditionally, this role has been dominated by centralized exchanges, which act as intermediaries between users.
As blockchain technology evolved, developers began building tools that could replicate core exchange functions without intermediaries. This is where decentralized exchanges came into play, forming a key pillar of decentralized finance (DeFi).
What Is a DEX?
A decentralized exchange is a crypto trading platform that allows users to swap digital assets directly with one another through smart contracts. There’s no central authority holding funds, managing accounts, or approving transactions.
When using a DEX, you always retain control of your private keys and funds. Trades are executed automatically by smart contracts deployed on a blockchain. In simple terms, instead of trusting a company, you trust open-source code.
This is fundamentally different from centralized exchanges, where users deposit funds and rely on the platform to safeguard and manage them.
CEX vs. DEX: What’s the Difference?
How Centralized Exchanges Work
On a centralized exchange, you deposit fiat or crypto into an account controlled by the platform. Trades happen off-chain inside the exchange’s internal system, and balances are updated in its database. While this setup is fast and user-friendly, it requires trust.
You don’t control the private keys to your funds, which means you’re exposed to counterparty risks such as hacks, withdrawals being paused, or platform failures.
How Decentralized Exchanges Work
DEXs remove this layer of trust. Trades happen on-chain through smart contracts, and users connect directly with their wallets. Funds are never handed over to the exchange itself.
Most DEXs operate on a single blockchain ecosystem, such as Ethereum or BNB Chain, although cross-chain solutions are emerging. The key principle remains the same: non-custodial trading with full user control.
Types of Decentralized Exchanges
Not all DEXs work the same way. Over time, several models have emerged.
On-Chain Order Books
In this model, every order, cancellation, or modification is written directly to the blockchain. This approach offers maximum transparency, but it’s slow and expensive due to gas fees and network congestion.
Off-Chain Order Books
Some early DEXs stored order books off-chain while settling trades on-chain. While faster, this approach introduced partial centralization and additional trust assumptions, which reduced its appeal over time.
Automated Market Makers (AMMs)
The AMM model has become the dominant design for DEXs today. Instead of matching buyers and sellers, AMMs rely on liquidity pools funded by users.
Trades are priced using mathematical formulas, allowing users to trade instantly at any time. Liquidity providers earn fees in return for supplying assets to the pools.
A well-known example is Uniswap, which popularized the constant product formula used by many AMMs today.
Popular Decentralized Exchanges
Several DEXs have become widely used due to their liquidity, reliability, and ease of use.
Uniswap is one of the most established AMM-based DEXs, known for its simplicity and deep liquidity across multiple blockchains.
SushiSwap started as a fork of Uniswap and expanded with governance features and additional incentives for users.
PancakeSwap operates on BNB Smart Chain and is popular for its lower fees compared to many Ethereum-based platforms.
Benefits of Using a DEX
One of the biggest advantages of DEXs is self-custody. You trade directly from your wallet, meaning no one else controls your funds.
DEXs are also permissionless. Anyone with an internet connection and a crypto wallet can participate, regardless of location.
They often list tokens that aren’t available on centralized exchanges, giving early access to new projects. Transparency is another major benefit, as all transactions are recorded on the blockchain and publicly verifiable.
Challenges and Risks of DEXs
Despite their advantages, DEXs aren’t without drawbacks.
Smart contract risks are a major concern. If the code has a vulnerability, it can be exploited, potentially leading to large losses.
Liquidity can be an issue on smaller platforms, causing slippage where trades execute at worse prices than expected. User experience is another hurdle, especially for beginners who must manage wallets, seed phrases, and gas fees themselves.
Frontrunning is also possible, as transactions are visible before confirmation, allowing others to jump ahead by paying higher fees. Finally, transaction costs can be high during periods of network congestion, depending on the blockchain used.
What’s Next for Decentralized Exchanges?
The future of DEXs looks promising. Layer-2 solutions and scaling technologies are already making trades faster and cheaper. Governance through decentralized autonomous organizations (DAOs) is giving users more influence over platform development.
Cross-chain trading is another exciting frontier, aiming to let users swap assets across different blockchains seamlessly. While still evolving, these innovations could make DEXs more accessible and efficient for everyday users.
Closing Thoughts
Decentralized exchanges are redefining how crypto trading works. By removing intermediaries and giving users full control over their assets, DEXs offer a powerful alternative to centralized platforms.
They do require more responsibility and technical understanding, but for many users, the trade-off is worth it. As decentralized finance continues to grow, DEXs are likely to play an even bigger role in the future of global, open financial systems.

CZ, the CEO of Binance, has just issued a warning about the risks of price manipulation and liquidity drain when listing tokens on centralized exchanges (CEX). He believes that the current listing process is enabling certain individuals or organizations to take advantage, significantly impacting the market and investors.
The Listing Process and the Phenomenon of Price Manipulation
According to #CZ , Binance announces the listing of tokens 4 hours before they officially trade. During this time, token prices often surge on decentralized exchanges (DEX), followed by heavy sell-offs on CEX once listed. This causes many investors to buy at high prices and incur losses as soon as the token trades on CEX.

Out of that, $3.3 billion came from CEXs and $2 billion from bridges.

To put it simply, the root cause of these hacks is centralization. For bridges, this usually involves the collateral that backs wrapped tokens💸. Since early 2023, bridges with wrapped tokens have lost popularity, which is why the number of hacks has also decreased.
So what makes DEXs secure, and what can replace bridges🤔?
Take DEX STON.fi as an example. All trades on it are executed through smart contracts on the blockchain. If the contract is written correctly, it can’t be hacked — unless someone hacks the $TON blockchain itself.
STON.fi is also actively developing cross-chain swaps without bridges or wrapped tokens. Instead, it uses HTLC and RFQ👇.
◾HTLC ensures atomic swaps — either both users receive tokens or neither does.
◾RFQ eliminates slippage by locking in the trade price in advance.
This setup removes all centralized elements from the system. All swaps happen peer-to-peer through smart contracts, giving users strong security and full control📈.

Currently, traditional on-chain exchanges face many problems: insufficient liquidity, slow transaction speeds, and high fees. It is difficult for users to obtain the best liquidity in the entire market on a single platform, resulting in low transaction efficiency, and high transaction costs further limit the user experience. In order to solve these pain points, dappOS launched a spot trading function based on intent infrastructure - IntentEX, to innovate the on-chain trading ecosystem.
Traditional transaction pain points: hindering user experience
Liquidity fragmentation: Most on-chain exchanges are unable to integrate CEX and DEX liquidity, and users often compromise between price and depth. Slow transaction speed: On-chain transactions need to wait for block confirmation, which is far slower than centralized exchanges (CEX). High handling fees: The handling fees are generally 0.2% or higher, especially for small transaction users who face a high cost burden.
