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.

Katana web and Ronin Wallet users

The interface for the swap feature differs between Katana web and Ronin Wallet:

  • Katana web: Access the swap feature via the Ronin web app.
  • Ronin Wallet users: Use the swap feature within the Ronin Wallet mobile app or browser extension.

Prerequisites​

To swap tokens on Katana, you need to have tokens in your Ronin Wallet. You can acquire tokens by depositing from Ethereum using Ronin Bridge, buying tokens through the Purchase website, or receiving tokens from other users. For more information, see Acquire RON.

Swap tokens on Katana web​

  1. Open Katana and connect your Ronin Wallet. The Swap page is selected by default.

  2. Choose the tokens you want to swap from and to.

    You can click either of the token selection boxes to reveal the full list of supported tokens.

    After choosing the swap pair, you can see the tokens listed on the Swap panel. The top token is the token you have in your wallet. The bottom token is the one you want to swap your token with.

  3. Enter the amount to swap: when you type in on one of the fields, the other populates based on the current exchange rate between the tokens.

  4. Optionally, switch the from and to tokens by clicking the arrows sign (⇅) between the tokens.

  5. When you are ready to swap, click the Swap button.

  6. In the Confirm Swap pop-up, review the details of your swap:

    1. The tokens to swap: ensure that the amounts are correct.
    2. Detailed swap information:
      • Rate: The exchange rate between the tokens.
      • Price impact: estimation of the slippage to expect based on your order size and market movements. This gives you an idea of how much you can receive.
      • Max. slippage: the highest percent of price movement of the transaction. Anything greater than this value results in a failed transaction.
      • Minimum receive: the lowest amount of tokens you can receive based on slippage tolerance. This is the worst-case scenario. Anything less than this value results in a failed transaction.
      • Liquidity provider fee: the fees allocated to LP provider (0.3% of the transaction value).
      • Route: the trading route taken for your order. It can be a direct "token A to token B" route, or there might be a bridge token in the middle, such as "token A through token B to token C." Direct route might not always be the cheapest.

  7. Click Confirm Swap to start the swap, then confirm the transaction in your Ronin Wallet.

A Swap submitted pop-up indicates that your transaction is submitted to the blockchain. You can close this pop-up or click View on explorer to view the transaction details in the Ronin Chain Explorer.

After a few seconds, your transaction is confirmed. You can see a banner appear on the browser window's top-right.

Congratulations. You just swapped your tokens on the Katana DEX.
