Welcome to Module 4 - Course 1 of Mission Web3!
In this module, we will dive deeper into understanding crypto exchanges— specifically Decentralized Exchanges.
Let's get started!
What is a Decentralized Exchange? (DEX)
Decentralized Exchanges (DEXs) operate on blockchain networks and aim to provide a peer-to-peer trading experience without a central entity.
DEXs operate on blockchain networks and allow users to trade directly from their wallets without relying on an intermediary. DEXs emphasize privacy, control over funds, and decentralization.
Here are some key characteristics of DEX:
DEXs allows users to retain control over their funds by conducting trades directly from their wallets. This eliminates the need to deposit funds into a centralized exchange, reducing the risk of hacks or theft. Additionally, DEXs prioritize privacy.
DEXs enable users to trade cryptocurrencies without relying on traditional order books through the use of liquidity pools. In a liquidity pool, users contribute their crypto assets to pool contracts, which are then used as liquidity. To represent this share, the user receives a seperate token These tokens are often referred to as liquidity pool tokens or LP tokens.
DEXs leverages the security and transparency of blockchain technology. Trades are executed through smart contracts, ensuring that transactions are executed with the specified parameters, which can be verified by the blockchain. This enhances the overall security and trustworthiness of the exchange.
DEXs enable individuals to trade freely without the risk of censorship or restrictions. As transactions occur directly between users, no central authority be default canimpose limitations on trading activities.
Now that we've explored the characteristics of DEXs, let's summarize their advantages and disadvantages.
Decentralized Exchanges Pros & Cons:
User control and privacy
Enhanced security and transparency
Potentially complex user experience for beginners
Here are some examples of popular decentralized exchanges (DEXs):
Uniswap: Uniswap is one of the most well-known and widely used DEX protocols. It operates on multiple chains such as—Ethereum, Polygon, Binance, Base, Optimism, Arbitrum, Celo, and Avalanche. It also allows users to trade various ERC-20 tokens.
PancakeSwap: PancakeSwap is a DEX that runs on the Binance Smart Chain (BSC). It gained popularity due to its low transaction fees and fast processing times.
