Uniswap is a DEX that allows users to trade ETH and ERC20 tokens directly from their wallets. It doesn't require users to create an account or deposit funds into a centralized exchange. Instead, it uses smart contracts on the Ethereum blockchain to facilitate trades. Since Uniswap is built on top of the Ethereum blockchain, it benefits from all of the security that Ethereum offers. The Ethereum blockchain is extremely secure and has never been hacked. This means that your funds are safe on Uniswap as long as you take the necessary precautions to secure your wallet. One of the advantages of using a DEX like Uniswap is that you retain full control of your funds at all times. On a centralized exchange, you must deposit your funds into the exchange's wallet. This means that you're trusting the exchange to keep your funds safe. If the exchange is hacked or goes bankrupt, you could lose your funds. With Uniswap, you always retain control of your funds. You can trade as often or as little as you want without having to worry about losing your funds.
