Swapping tokens on the Solana network normally requires a small amount of SOL to cover transaction (gas) fees. If you don’t have enough SOL in your wallet, the swap would typically fail.
Gasless swaps, available in the Phantom mobile app, solve this by allowing the transaction to go through even when your SOL balance is too low. Instead of paying the network fee in SOL, Phantom deducts a fee from the token you’re swapping from and handles the gas behind the scenes.
When a gasless swap is triggered
Gasless swaps are triggered automatically when the following conditions are met:
- You're using the Phantom mobile app.
- You don't have enough SOL to pay the transaction fee.
- You're swapping a token that is verified.
- Your swap amount is $10 or more.
- Auto-slippage is enabled, or manual slippage is set to 0.5% or higher.
If your swap qualifies, there’s nothing to enable—Phantom will take care of the rest.
Fees
When a gasless swap is triggered, Phantom deducts a 1.5% total fee from the token you’re swapping from. This fee consists of:
- 0.85% Phantom fee for sourcing optimal pricing through liquidity providers.
- 0.65% premium transaction fee to process the transaction when you lack native tokens.
Both fees are automatically included in the quote shown before you approve the swap.
FAQ
Can you use gasless swaps on desktop?
Not at the moment. Gasless swaps are currently available only in the Phantom mobile app.
Why didn't your swap go through as gasless?
Even if you’re using the Phantom mobile app and your swap is over $10, some swaps may still not qualify due to additional criteria. For example, gasless swaps may not apply if:
- The token you’re swapping is unverified or not trending.
- The token has low market cap (less than $50K).
- The total fee exceeds 10% of the token’s value.
- Auto-slippage is disabled and manual slippage is set below 0.5%.
- You’re using advanced settings like exact output or manual tip input.
