Ronin Wallet and Katana DEX: How to Start (2026)
Updated October 2026
To use Katana DEX you need a Ronin Wallet, a little RON in it for gas, and the official Katana address, app.roninchain.com/swap. Install the wallet only from the links on Ronin’s own sites, write down your recovery phrase offline, add RON, then connect the wallet to Katana and swap. This guide takes a complete beginner through each step in order.
Key takeaways
- Ronin’s documentation says Katana is “the official DEX supported on Ronin”. Its swap page is app.roninchain.com/swap.
- You connect a Ronin Wallet to Katana. Ronin’s docs link the wallet from wallet.roninchain.com, with iOS and Android downloads listed in its guide to acquiring RON.
- RON is the gas token. Ronin said in May 2026 that it “will continue to use RON for gas” after becoming an Ethereum Layer-2.
- Katana DEX on Ronin is not the same project as Katana Network (katana.network).
- Katana.so is an independent guide. You cannot swap on this site.
What is the Ronin Wallet?
The Ronin Wallet is the wallet Ronin points users to for storing RON, receiving tokens and signing transactions on apps like Katana. Ronin’s own blog lists downloading it as step 1 for people new to Ronin. You will find it on mobile and, according to Ronin’s swap documentation, as a browser extension too.
A wallet does not hold coins the way a bank account does. It holds the keys that prove you own the tokens, and the tokens themselves sit on the blockchain. Whoever has your keys controls your funds, so protecting them is the most important part of this guide.
What is Katana DEX, and how does it relate to Ronin?
Katana DEX is the decentralized exchange on the Ronin blockchain. A decentralized exchange, or DEX, lets you swap tokens straight from your wallet using pools of tokens deposited by other users, with no account to open. For fees, V2 versus V3 and how pools work, read our Katana DEX guide. For the chain itself, see Ronin Network explained.
Ronin announced on May 13, 2026 that it had moved from a standalone chain to an Ethereum Layer-2 built on the OP Stack. The announcement said the migration does not change Katana liquidity pools or tokens such as AXS and SLP. For you as a beginner, the steps below stay the same.
Is Katana DEX the same as Katana Network?
No. The names match, but the projects are separate.
| Katana DEX (Ronin) | Katana Network | |
|---|---|---|
| What it is | A decentralized exchange | An Ethereum Layer-2 blockchain |
| Where you use it | app.roninchain.com/swap | app.katana.network |
| Chain ID | Not applicable, it is an exchange | 747474 |
If you searched for “Katana Ronin” and want the Ronin exchange, you are in the right place. If you want the other chain, start at katana.network.
How do I get the Ronin Wallet safely?
Get it only from an official source. The first two steps come from Ronin’s documentation, and the third is a general safety habit:
- Go to roninchain.com and open the Wallet link, which points to wallet.roninchain.com. Type the address yourself or use a bookmark you made from the official site.
- On a phone, use the store links in Ronin’s guide at docs.roninchain.com/basics/acquire-ron. They lead to the Ronin Wallet listings on the Apple App Store and Google Play.
- General advice, not from Ronin: check the publisher and the app name before you install. Do not install from a link sent to you by message, an ad or a social media reply.
Ronin’s docs also link a setup guide, “Getting Started on Ronin Mobile Wallet”, on the Ronin support site. Follow it for the exact screens on your phone.
How do I set up the wallet and protect my recovery phrase?
When you create a new wallet, the app gives you a recovery phrase, also called a seed phrase. This is a list of words that can restore your wallet on any device. These are general wallet safety rules, not Ronin-specific claims:
- Write it on paper and store it somewhere private. Avoid screenshots, cloud notes and photos.
- Never type it into a website or send it to anyone, including people who say they are support staff. A real wallet app or exchange never needs it to “verify” you.
- Keep a second copy in a separate safe place, in case the first is lost or damaged.
- Test with a small amount first before moving larger sums.
Anyone who has the phrase can empty the wallet. If you lose it and lose your device, nobody can recover the funds for you.
How do I fund the wallet with RON for gas?
Every transaction on Ronin, including a swap, costs a small fee in RON. Keep a little RON in the wallet before you try anything. Ronin’s documentation names these routes:
| Route | How it works |
|---|---|
| Exchange withdrawal | Buy RON on a centralized exchange, then withdraw it to your Ronin Wallet address. Ronin lists Binance, Coinbase, OKX, Crypto.com, Gate.io, Bitget, MEXC and Coins.ph. Some are restricted in certain regions. |
| On-ramp | Buy in the mobile app under dApps, then Purchase, or at purchase.roninchain.com. Ronin names Ramp and OnMeta as partners. |
| Bridge from Ethereum | Use the Ronin Bridge at app.roninchain.com/bridge. Ronin’s docs say you need ETH for gas on the Ethereum side. |
Check the network on your withdrawal screen before you confirm. For a step-by-step buying walkthrough, use our guide to buying RON. If you need to double check a token address, see the RON token contract address page.
How do I open Katana DEX and make my first swap?
Ronin’s docs list the Katana swap page as app.roninchain.com/swap. Their steps for the web app are:
- Open app.roninchain.com/swap and connect your Ronin Wallet. The Swap page opens by default.
- Click either token box and pick the token to swap from and the token to receive.
- Enter an amount in either box. The other box fills in at the current rate. Expand the exchange rate box to see more detail, then click Swap.
- In the Confirm Swap pop-up, review the details and click Confirm Swap. Then approve the transaction in your Ronin Wallet.
- When a confirmation appears, use View on explorer to see the transaction.
You need the tokens in your wallet first. Ronin’s docs say you can get them by bridging from Ethereum, using the Purchase page or receiving them from another user.
What should I check before I confirm?
- Max. slippage: the transaction fails if the price moves beyond this value.
- Minimum receive: the transaction fails if you would get less than this.
- Price impact: an estimate of how much your own order moves the price.
- Route: Ronin’s docs note the direct route “might not always be the cheapest”.
The swap fee is paid in the token you put in. For the full fee table, read the Katana DEX guide. Ronin’s docs add that swapping inside the Ronin Wallet app, called Wallet Swap, adds a 0.5% development fee paid in the output token. To go beyond swapping, see our RON farming guide.
How do I avoid fake Katana and Ronin sites?
These are general safety habits, not Ronin guidance:
- Reach Ronin tools from roninchain.com or docs.roninchain.com, then bookmark them.
- Do not trust search ads or links in replies and direct messages, even if the page looks identical.
- Remember that a real site connects your wallet and asks you to approve a transaction. It never asks for your recovery phrase.
- Read each wallet prompt before approving. If you do not understand what you are signing, stop.
- Do not confuse Katana.so with an app. This site is an independent guide and is not operated by Sky Mavis or Ronin.
