Solana priority-fee & throughput stats — hourly snapshots

Hourly snapshots of Solana mainnet priority fees over the last ~150 slots (p50/p75/p90/max micro-lamports per CU, share of slots paying a fee) plus recent TPS. Pick a fee that lands without overpaying; 30-day history for backtests. Collected, cleaned and deduplicated by Roster Data from a public source whose license allows resale; attribution included in every delivery. You only pay when data is delivered.

What you get
