# Solana Fees

**Network Fees & Priority Tips**

Indexify sponsors **base gas fees**, so you don’t need to hold SOL to trade.\
However, there are additional costs that may apply when trading during high network activity.

***

**Slippage Tolerance**

* **Slippage** is the difference between the expected price of a trade and the actual execution price.
* Setting a slippage tolerance ensures your transaction still goes through if prices move slightly during confirmation.
* If the market moves beyond your tolerance, the transaction will **fail** instead of filling at a worse price.

**Best practices:**

* Use **low slippage (0.1%–0.5%)** for stable pairs or low volatility.
* Use **higher slippage (1%–5%)** for volatile or low-liquidity tokens. some tokens may at times even require more.
* Balance safety (avoid bad fills) with execution certainty (avoid failed txns).

***

> ⚠️ **Warning**\
> Very high slippage can expose you to **front-running or poor execution**. Adjust carefully based on market conditions.

**Priority Tip**

* A **Priority Tip** is an optional extra payment made to validators.
* It helps increase the likelihood of **faster trade confirmations**, especially:
  * During high network congestion
  * On high-volume tokens

**How it works:**

* Enter the amount you are willing to pay for prioritization.
* **Default value:** `0.0015`
* Higher tips = higher chance of faster execution.
