Get Intent Quote
endpoint, set the feeBudget parameter to your desired priority fee plus
the base processing fee (10,000 lamports).When using Get Intent
Quote, remember
to add the base processing fee (10,000 lamports) to your desired priority fee
when setting
feeBudget. Example: For a 5,000 lamport priority fee, set
feeBudget to 15,000 lamports.How It Works
- The fee you specify will always be applied.
- No automatic adjustments are made.
- If the network requires higher fees, your swap may be delayed or fail.
The priority fee must always be at least 1 lamport; otherwise the swap will
never be processed.
