Do I need Ethereum to swap on Uniswap?

Are you wondering if you absolutely need Ethereum to make swaps on Uniswap? Well, let's delve into it. Uniswap, being a decentralized exchange built on the Ethereum blockchain, primarily utilizes ERC-20 tokens for trading. This means that while Ethereum (ETH) is the native currency of the Ethereum network and often used for gas fees, you don't necessarily need to hold ETH to swap tokens on Uniswap. However, you will need some form of cryptocurrency to cover the transaction fees, known as gas fees, which are typically paid in ETH. So, while you don't necessarily need to hold ETH to swap tokens, having some ETH in your wallet can be beneficial to cover those transaction costs. But, the key takeaway is that you can swap tokens on Uniswap without owning Ethereum, as long as you have a suitable cryptocurrency to cover the gas fees.
