A decentralized exchange (DEX) is a platform where users can trade cryptocurrencies directly with each other without an intermediary. Instead of a company managing the trades, transactions are executed through smart contracts on a blockchain. This allows users to retain full control over their funds at all times.

A decentralized exchange enables peer-to-peer trading without relying on a central authority.
Decentralized exchanges work using smart contracts that automatically match and execute trades, often through liquidity pools instead of traditional order books. Users connect their wallets to the platform and trade directly from them, without depositing funds into the exchange. This reduces counterparty risk and aligns with the principle of decentralization. However, DEXs may have lower liquidity, higher transaction costs depending on the network, and a steeper learning curve compared to centralized exchanges. Additionally, users are fully responsible for their own security, meaning lost keys or mistakes cannot be reversed.
For investors, decentralized exchanges offer greater control, privacy, and access to a wide range of tokens, especially newer or less widely listed assets. They also enable participation in DeFi activities such as yield farming and liquidity provision. On the other hand, risks such as smart contract vulnerabilities, price slippage, and user errors must be carefully considered. Understanding how a DEX operates is essential before using it for trading.
Short example:
Suppose you want to swap Ethereum for another token.
You connect your wallet to a decentralized exchange and select the tokens you want to trade.
The smart contract executes the trade using a liquidity pool without any intermediary.
The new tokens are sent directly to your wallet, while you remain in full control of your funds throughout the process.
