getRecentPrioritizationFees

Last updated:

getRecentPrioritizationFees returns a list of the prioritization fees observed in recent blocks — up to the last 150 blocks. Each entry pairs a slot with the prioritizationFee (in micro-lamports per compute unit) that was sufficient to land a transaction in that block.

Use this method to size the priority fee before submitting a transaction. A common strategy is to fetch the recent fees, take a percentile (for example the median or the 75th percentile of the non-zero values), and set your compute-unit price accordingly via a ComputeBudget instruction.

The optional addresses parameter narrows the result to blocks where a transaction wrote to one of the given accounts (write-locked them). This yields a fee estimate tailored to the accounts your transaction will touch — useful when a specific account is contended. Omit addresses to get the global recent-fee picture across the cluster.
