# Tips

## Managing Slippage and Price Impact

### **Slippage Settings:**

* Use average slippage (0.5%–1%) for liquid, high-volume token pairs
* Increase slippage tolerance (2%–5%) for low-liquidity tokens or during volatile market conditions
* Avoid excessively high slippage settings, as they can result in unfavorable execution prices

### **Reducing Price Impact:**

* **Split large exchanges into multiple smaller transactions** to reduce price impact
* Monitor price impact warnings — exchanges with impact exceeding 5% should be reduced or delayed
* Check pool liquidity depth before executing large swaps (see [**Pool**](https://wemix.fi/pool) for liquidity information)
* Execute exchanges during periods when market conditions stabilize over 10-30 minutes, allowing liquidity to replenish

#### Example

A single 5,000 WEMIX swap with 3% price impact ($150 loss) can be split into five 1,000 WEMIX swaps with 0.6% price impact each ($30 total loss), reducing slippage by 80%.

## Cost Optimization

### **Gas Fee Management:**

* Ensure sufficient WEMIX balance before initiating swaps to avoid transaction failures
* Monitor gas fee estimates during network congestion periods
* Combine multiple small trades into fewer larger transactions when appropriate to save on cumulative gas costs

### **Token Approval Best Practices:**

* First-time swaps for each token require a separate approval transaction
* Approval is a one-time action per token contract
* Unlimited approval eliminates future approval steps but increases smart contract exposure
* Consider limited approval amounts for tokens with unknown or unaudited contracts

## Transaction Troubleshooting

For common issues such as failed transactions, slippage errors, insufficient liquidity warnings, or balance display problems, refer to the [**Support → Help Center**](https://wemix-fi.zendesk.com/) section for detailed resolution steps.
