Curve Finance is a decentralized exchange (DEX) running on Ethereum. It's specifically designed for swapping between stablecoins. All you need is an Ethereum wallet, some funds, and you can swap different stablecoins with low fees and slippage. You could think of Curve as "Uniswap for stablecoins." Thanks to its special pricing formula, it's also great for swapping between different tokenized versions of a coin.
