Solana Priority Fee API – Developer Guide
The Solana Priority Fee API allows developers to programmatically retrieve priority fee estimates based on current network conditions. Rather than querying raw RPC data, dedicated fee APIs provide processed, actionable estimates tailored to your transaction type and urgency level.
getRecentPrioritizationFees RPC Method
Solana's native getRecentPrioritizationFees method accepts an array of account addresses and returns the minimum fee required to include at least one transaction touching those accounts in each of the last 150 blocks. This gives a lower-bound estimate useful for low-priority transactions but may underestimate fees needed during congestion.
Helius Priority Fee API
The Helius getPriorityFeeEstimate method accepts a serialized transaction or account list and returns fee estimates across six priority levels: Min, Low, Medium, High, VeryHigh, and UnsafeMax. It considers both global and local fee markets, making it more accurate than the raw RPC method for production applications.
Implementing Dynamic Fee Logic
Best practice for production applications is to implement retry logic with escalating priority fees. Start at the Medium level, retry failed or slow transactions at High, and use VeryHigh only when speed is critical. Always cache recent fee data to avoid excessive API calls, and update your estimates every 10–20 seconds during volatile market conditions.
