Solana · blockspace fee market
What does it cost to land a transaction right now?
mevscope reads the priority-fee floor of recent slots across the busiest programs on Solana, then turns it into the one number you act on: the compute-unit price that gets your transaction included — and how much of that is the free lottery everyone forgets.
Reading recent slots…
The blockspace fee curve
Every point is a recent slot's minimum priority fee, sorted cheapest to most expensive. The floor sits at zero for most of the curve — then explodes in the top percentiles, where real competition for inclusion lives. Log scale.

What tip lands you
To be included in a target share of recent slots, set your compute-unit price to at least this. Pick a compute budget to see the priority fee it adds.

Why the median is zero
getRecentPrioritizationFees returns the lowest fee that still landed in each slot. Most slots have spare room, so something always lands for free — the median floor is zero, and that is not a bug, it is the base rate.
What a CU price buys
Your priority fee is CU price × compute budget. Bidding above the slot's floor front-runs the mempool-free scheduler, so the tail percentiles are the price of reliable inclusion, not of inclusion at all.
How the sample is built
We pool the fee floors of recent slots across the heaviest Solana venues — AMMs, the perps and launch programs — so the curve reflects contention where traders actually fight for blockspace, not an idle account.
