A priority fee helps your transaction get processed faster when the Solana network is busy. Phantom sets this to Auto by default, which adjusts based on real-time conditions. You can also set a custom value if needed.
How to set a custom priority fee
- During a swap, select the Settings icon in the upper right.
- Select Priority Fee → Custom.
- Enter a value, then confirm.
Thresholds
| Threshold | SOL |
|---|---|
| Minimum | 0.0001 |
| Warning (too low) | Under 0.0001 |
| Warning (too high) | Above 0.05 |
| Maximum | 1 |
If you set a fee outside the allowed range, the transaction won't go through. Phantom shows a red banner if the value is out of range, and a warning if it's unusually low or high.
When to use a custom fee
- Network is busy: Increase slightly for faster confirmation
- Transaction is stuck: Retry with a higher custom fee
- Network is quiet: Auto is usually enough
