Decentralized Exchanges (DEXs) have become a cornerstone in the web3 ecosystem, surpassing traditional exchanges with their innovative approach to trading digital assets.

Unlike centralized exchanges like Binance or Coinbase, which operate as intermediaries, DEXs function without central authorities. This decentralized nature offers users enhanced control over their assets, improved privacy, and better security.

Unlike centralized exchanges where user funds are held and controlled by the exchange, DEXs utilize smart contracts to facilitate direct token swaps between users, who connect their crypto wallets for seamless transactions.

However, while DEXs offer significant advantages, they also pose challenges such as limited liquidity for less popular tokens. Despite these challenges, their contribution to the web3 ecosystem is undeniable, offering a reliable and secure alternative for cryptocurrency trading.

This has driven many startups to explore and launch their own decentralized exchanges, recognizing the potential for better user control, security, and privacy.
