Sushi 🍣

This guide shows how to mint uAssets on Universal.xyz, then set up new pools and provide liquidity on Sushi v3 on the Katana network.

uAssets are 1:1 backed, wrapped versions of tokens, including non-EVM assets like SUI, DOGE, and SOL, brought on-chain via institutional-grade minting. With over 80 uAssets available, all can be traded on Sushi once pools are live.

This unlocks a new layer of liquidity, enabling EVM users to trade and LP non-EVM assets directly on Katana via Sushi.

Since most pools haven’t been created yet, this guide shows you how to mint a uAsset and create a new pool. Once pools exist, you won’t need to repeat this, unless a new uAsset or trending token emerges.

#1: Mint uAsset on Universal.xyz

1. Visit Universal.xyz

Visit Universal.xyz, make sure your wallet is connected to the Katana network.

If you do not have asset on Katana, you can bridge assets like USDC or ETH using one of the following options:

SushiXSwap: sushi.com/katana/swap
Katana App: app.katana.network

See the full Katana Tutorial.

2.Choose the uAsset you want to activate on Katana

On the Trade tab, you’ll see featured uAssets like uSUI, uXRP, and uADA.
Click on the asset you want to bring to Katana. In this example, we’ll bring uSUI, which you can select directly from the Featured section or by searching in the dropdown menu.

3. Choose USDC to Swap Into uSUI

In the Sell field, select USDC and input the amount (e.g., 17.63 USDC).
In the Buy field, select uSUI.
The app will auto-calculate the output based on live RFQ pricing.

4. Review the Quote

Click Review trade once the app displays a firm quote (in this case, 6 uSUI for 17.63 USDC).

Details like the exchange rate, selected network (Katana), and network cost (free) will appear.

5. Confirm the Trade

Click Confirm trade.

Your wallet (MetaMask) will prompt you to approve spending USDC. Confirm the approval.

6.Add uSUI to Wallet

Meanwhile, you can click Add to wallet to make uSUI visible in your wallet.

7. Done

Once complete, your wallet holds uSUI—a 1:1 backed, on-chain version of SUI, now ready for trading, LPing, or use in any Katana-based DeFi strategy.

#2: Provide Liquidity on Sushi v3

Once you’ve minted uSUI, you can deploy it into a Sushi v3 liquidity pool to start earning swap fees and potentially protocol rewards. If your token pair doesn’t yet exist, you can also create the pool yourself.

Step 1: Go to the Pool Page

Visit: https://sushi.com/katana/pool
Connect your wallet and click “I want to create a position.”

Then, choose “V3 Position” from the dropdown.

Step 2: Choose Your Token Pair

Select the token pair you want to LP.
In this example, we’ll use vbUSDC/uSUI.

If you already hold uSUI but can’t find it in the list:

You can return to Universal.xyz, search uSUI, and copy the token contract address

Paste it into the Sushi token selector to load the token manually.

Step 3: Select a Fee Tier

Back to Sushi UI, pick the fee tier that best fits the pair’s volatility:

0.01% – Best for very stable pairs (e.g., stable/stable)
0.05% – Less volatile pairs
0.3% – Best for most common pairs
1% – For highly volatile or exotic tokens

Step 4: Initialize the Pool with Start Price and Price Range

If the pool you selected doesn’t exist yet (e.g. vbUSDC/uSUI), Sushi v3 will ask you to initialize it. This means you need to manually set a starting price and a liquidity range before you can deposit.

This step is common when working with newly launched uAssets, since pools may not yet exist. If the pool is already set up, you can skip this and follow the standard Katana v3 liquidity guide here:
Add Liquidity on Katana via Sushi v3

a. Get the Start Price

To set the start price, go to Universal.xyz, select the reverse pair (e.g. 1 USDC → uSUI), and note the output.

In our case:
1 USDC ≈ 0.3517 uSUI
Set this as your Start Price in the Sushi UI.

b. Define a Price Range

Once the start price is set, choose a range using presets or manually:

Example of using x/1,2:

Min Price: 0.29336
Max Price: 0.42301

This creates a tight range around market price with:

11.44x capital efficiency
50:50 token ratio

You’ll earn fees only while the price stays within this range.

See the full Katana v3 liquidity guide here to understand more on how to set your price range:
Add Liquidity on Katana via Sushi v3

Note: This step only appears for brand-new pairs. If the pool already exists, you can skip this and go straight to depositing.

Step 5: Input Token Amounts

Enter how much of each token you want to deposit.
Note: The required ratio is based on your price range, not necessarily 50/50.

Note:
A pool needs at least $1,000 of each token to be priced properly.
For demo purposes, we’ve only added a small amount to showcase the flow.

Step 6: Approve Tokens

Click Approve for each token.
Your wallet will prompt you to grant permission for Sushi to use the assets.

Step 7: Preview and Confirm

Click Preview, review your position summary (price range, slippage, token amounts), and click Add Liquidity.

Confirm the transaction in your wallet.

You’ll see a message confirming your LP position was created.
You can click “View on Explorer” to verify the transaction onchain.

Step 8: Manage Your Position

Return to the Pool page and go to the “My Positions” tab.
Here, you can monitor your position, check unclaimed fees, rebalance your range, or withdraw liquidity.

#3: Trade SUI on Sushi
