getRecentPrioritizationFees

Returns a list of prioritization fees from recent blocks. Prioritization fees are additional fees paid to incentivize validators to include a transaction in a block more quickly. This method is critical for applications that need to dynamically set compute unit prices to ensure timely transaction inclusion during periods of high network congestion, such as NFT mints or DeFi trading.

Parameters

#TypeRequiredDescription
1array[string]NoArray of base-58 encoded account addresses (max 128). If provided, returns fees for transactions that write-lock these accounts

Response

Returns an array of prioritization fee objects:

FieldTypeDescription
[].slotu64Slot in which the fee was observed
[].prioritizationFeeu64The per-compute-unit fee paid by at least one transaction in the block, in micro-lamports
