Anyone who buys cryptocurrency is probably familiar with the process of setting up an exchange account and buying crypto with dollars, but many have never used a decentralized exchange, or”DEX‘ to exchange one cryptocurrency for another. While DEXs have many amazing benefits for the entire industry, they also pose regulatory and consumer protection challenges and are often used by scammers and hackers as tools to support crypto crime.
SCREENRANT VIDEO OF THE DAY
To buy cryptocurrencies using fiat currency (i.e. digital dollars), buyers typically open an account with a centralized exchange such as Coinbase or Binance. All centralized exchanges require users to deposit their funds/crypto in order to buy/sell anything, which can be devastating if the exchange is hacked. Exchange hacks were so common in the early years of blockchain that crypto veterans now distrust centralized exchanges and store their crypto on hardware wallets to protect them from hackers until they are ready to sell them. This was the reality for many crypto holders for several years until the Uniswap protocol changed everything.
Uniswap was the first DEX (also referred to as “Automated Market Maker” or AMM) to see mass adoption by crypto users. A DEX is a crypto swapping app that uses blockchain smart contracts to exchange tokens, allowing users to buy/sell crypto directly from their wallets. As Coinbase explains, DEXes allow users to list and sell cryptocurrencies without intermediaries, which has been a miracle for new crypto projects. DEXes are designed for the ERC-20 fungible token standard, which also makes them compatible with all stablecoins (cryptocurrencies stable up to a dollar) but not compatible with NFTs. Today, thousands of cryptocurrencies are sold on DEX, and crypto prospects looking for a “1000x gem” need to know how to use one. Despite the simplicity of their interfaces, DEXes aren’t easy to use for crypto newbies, as they deal exclusively with cryptocurrencies, require the user to connect a wallet and pay their own gas fees, and the user needs to be sure they’re buying for the right thing trades signs.
DEXs are innovative, but also problematic
Ethereum-compatible DEXs use “pools of liquidity” instead of traditional order books to facilitate trading. Order books are practically impractical to use on Ethereum and similar blockchains for a number of reasons, so liquidity pools were created to solve these problems. A liquidity pool is a smart contract where “liquidity providers” provide the tokens (“liquidity”) that other users trade and offer a share of the trading fees as an incentive to do so. As CoinTelegraph explains in detail, providing liquidity is extremely risky and should only be pursued by advanced users who can mitigate the risk. A major benefit of DEXs is their ability to remain operational when centralized exchanges go offline during periods of high volatility, and since DEXs can be used by other smart contracts, they can allow Web3 companies to accept any token as a payment method.
However, DEXs also have disadvantages. Large trades can cause “slippage”, which significantly affects the price of a token and reduces the final amount received, making it difficult to provide limit order functionality to users. DEXes also cannot trade tokens across blockchains, but are limited to tokens built on the same blockchain. DEXs are also a regulatory nightmare, as they are often used by hackers to exchange stolen stablecoins before going through a crypto-mixing service like Tornado Cash. Scammers also use DEXs to list their crypto scam coins and have the opportunity to empty their liquidity pool once enough victims have traded legitimate coins for the scam coin, bringing the price down to zero.
DEXs are a critical piece of infrastructure in Decentralized Finance, allowing users and smart contracts alike to exchange any two (same-chain) cryptocurrencies in one transaction. They are so important that every smart contract blockchain has at least one such as: B. PancakeSwap on Binance Chain, Quickswap on Polygon or Raydium on Solana. Even if it is sometimes problematic DEXIt is a powerful blockchain innovation that has the potential to shape the future financial system and will be an invaluable component of the blockchain-powered Web3 internet era, although how regulators will address its issues is unknown.
