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, thanks to using smart contracts to facilitate the exchange. As an automated market maker (AMM), Katana is always ready to buy and sell any tokens immediately.

Swap on Katana web vs Ronin Wallet

The swap experience differs between Katana web and Ronin Wallet:

Katana web users: Use the Katana > Swap page in the Ronin web app.
Ronin Wallet users: Use the Wallet Swap dApp in the Ronin Wallet mobile app or browser extension. Each swap transaction using Wallet Swap incurs a development fee of 0.5% of the transaction value.

Swap fees

When swapping tokens, you incur the following fees:

Fee	Katana web	Wallet Swap
Development fee	-	0.5%
Ronin treasury fee	0.05%	0.05%
Liquidity provider fee	0.25%	0.25%

Prerequisites

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

Swap tokens on Katana web

Open Katana and connect your Ronin Wallet. Katana opens on the Swap page by default, with the Swap panel in the middle.
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.
Enter the amount to swap by typing in either of the token selection boxes. When you type in on one of them, the other populates based on the current exchange rate between the tokens. When you are ready to swap, click Swap.

To view detailed information about the swap before proceeding, expand the exchange rate box above the Swap button.
In the Confirm Swap pop-up, review the details of your swap:
- 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 liquidity providers.
- 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." The direct route might not always be the cheapest.
When you're ready, click Confirm Swap, then confirm the transaction in your Ronin Wallet.

Your transaction is now submitted to the blockchain. When it completes, Katana displays a confirmation pop-up. Close it or click View on explorer to see the detailed information about the transaction.

Swap completed

Congratulations. You just swapped your tokens on Katana.
