Swap on SKALE via Sushi

1. Visit the Sushi Website
   Navigate to the Sushi interface by visiting Sushi.

2. Connect Wallet
   Use a compatible wallet, such as MetaMask, and connect by following the prompt.

3. Change Network to SKALE
   In the network selection area, switch from the default or current network to SKALE. Ensure your wallet is connected.

4. Select Tokens to Swap
   Choose the tokens you wish to swap. Click on the token list to see more options in the dropdown menu. Select the tokens you want to swap from and to.

5. Enter Swap Amount
   Input the number of tokens you want to swap. 

6. Approve the tokens 
   You will have to approve the tokens you want to swap, follow the wallet instructions and click “Approve”.

7. Execute the Swap
   Click “Swap” to initiate the transaction, then click “Confirm” in your wallet interface to execute the swap. Upon successful transaction, you've effectively swapped tokens on SKALE.

LP on SKALE via Sushi (v3)

1. Visit the Sushi Pool UI
   Navigate to the Sushi Pools interface by visiting Sushi Pools.

2. Connect Wallet and Change Network
   Connect your wallet and change the network settings to SKALE if you haven’t already done so.

3. Select a Pool
   Choose a liquidity pool you're interested in LPing, for example, USDC/ETH

4. Select Price Range

Determine the price range within which you're willing to provide liquidity. There are two ways to do this:

• Adjust the price range bar to set the minimum and maximum price.
• Enter specific values into the designated boxes.

Remember that a narrower price range can result in higher fee collection but also increases the risk of being out of range and not earning any fees. Opting for the full range is equivalent to the classic v2, with no concentrated liquidity.

5. Provide Liquidity Amount

Enter the amount for one token in the pair. The protocol will populate the other token. If one token exceeds the amount, try inputting the other one first. Then click on “Preview”.

6. Approve Tokens

Just like swapping, you need to approve the spending cap for the tokens. Click “Approve (TKN)” and approve the tokens one by one on your wallet.

7. Review & Confirm
   
   Follow the instructions on the UI. Click “Preview”, then “Add Liquidity”. Confirm the transaction in your wallet.

8. Manage Position

After adding liquidity, you can manage your position by selecting “My position” under the Pools UI. This allows you to adjust or remove your liquidity as needed.

LP on SKALE via Sushi (v2)

Step 1:

First, head over to the Sushi app and select Enter App in the upper right corner. Next, make sure your wallet is connected and select the Pools tab on the upper left corner of the screen to be brought to the pools page.

Step 2:

Once on the Pools page, click on the drop-down menu at the end of I want to create a position to see both V3 Position and V2 Position. In this case, select V2 Position. This will bring you to the Add Liquidity page, where you can provide liquidity to an existing pool, or you can choose to create a new pool.

Step 3:

Choose SKALE on the network. Select a token pair. Add the amount you want to provide liquidity to.

Note: Both tokens will automatically represent a 50/50 balance, so make sure you have enough tokens of each in your wallet. Also, ensure your wallet is on the same network as the network you are providing liquidity to.

Step 4:

Approve the tokens on your wallet.

Step 5:

Add liquidity and confirm on your wallet.

Step 6:

Done. You can see your position on the pool page.
