getPriorityFeeEstimate

Last updated:

`getPriorityFeeEstimate` returns a **recommended priority fee** — the per-compute-unit price (in micro-lamports) that a transaction should attach so that it lands reliably given recent network conditions. Solana orders pending transactions in part by the priority fee they bid, so a sender uses this estimate to set a `ComputeBudgetProgram.setComputeUnitPrice` instruction before signing.

Use it just before submitting a transaction: query the estimate, apply it to the compute-budget instruction, then send via [`sendTransaction`](./sendTransaction.md). Because network demand shifts from slot to slot, fetch a fresh estimate per submission rather than caching one.

This is a read method in the `sol_read_rpc` category (free tier and up). It does not submit or simulate anything — it only reports a fee recommendation.
