Swap

Overview​

You can swap tokens on Katana to trade one token for another. Swapping is a decentralized process that doesn't require a traditional bank or other trusted third party. This is made possible by using smart contracts to facilitate the exchange. As an automated market maker (AMM), Katana is always ready to buy and sell any tokens immediately.
