# Swap
### **Step 1. Select Tokens to swap**
**Component description**
1. **From token select section**\
The place where users can select the token they want to swap
2. **To token select section**\
This is where users can select the token they want to obtain through the swap
Selecting from token and to token (example)
Select the from token and to token at “Swap” menu.
### Step2. Input Values to swap
**Step2–1 Input token amount**
Users should input the amount of tokens they want to swap.\
However, for the “from” token, they cannot input an amount greater than what they currently possess; otherwise, the swap cannot be executed.
**Step 2–2 set slippage tolerance ratio**
*DEX slippage* refers to the difference between the expected price of a trade and the actual executed price on a decentralized exchange (DEX).\
It occurs due to the changing supply and demand of assets in a liquidity pool by other users’ transaction.\
The default value for this is set at 0.1%, and users can adjust it up to a maximum of 50%.
**Step 2–3 Estimated swap result**
Before executing a Swap, shall we check the following details?
**Component description**
1. **You will receive**\
The amount of tokens you will receive after the swap.
2. **Price Impact**\
The effect of a trade on the price of a token on a decentralized exchange due to changes in supply and demand. If the pool has very low liquidity, it is recommended to make small and frequent trades.
3. **Minimum received after slippage**\
Based on the current set slippage ratio, the minimum token amount that a user can receive.
4. **Swap Fee**\
The swap fee imposed when executing the swap.
5. **Optimized Swap Route**\
The most optimized swap route for the user to swap the current token.
### Step 3. Approve token
If the amount you entered for the “from” token is not approved, an approval process for the “from” token is required before the swap can be executed.
Please approve the amount you entered, which should be equal to or greater than the Minimum Approve Amount, in your Wallet app. If you enter a smaller amount, the approval process will be repeated until the appropriate value is entered.
### Step 4. Proceed swap
To proceed with the swap process, click on the “Execute Swap” button.
### Step 5. Completion page
The swap has been completed successfully. You can check the user’s swap transaction history by clicking on the “Transaction Details” button.
### Step 6. My history section
