Fee Market
Block space is a market. When the mempool fills faster than miners can clear it, the fee rate required to confirm climbs. Watch the queue, the projected next blocks, and the historical clearing price below.
Rough — assumes the mempool doesn't change while you wait. Real wait is sensitive to new fee bumps and miner luck.
How to read this
Wallets pay miners by including a fee with each transaction. Miners select transactions from their mempool fee-rate-descending, so the price of inclusion is set by whoever else is paying right now. There is no fixed price — it floats with demand.
The projected blocks above are what would happen if no new transactions arrived: the highest-fee bundle fills the next block, the next-highest fills the one after, and so on. In practice the mempool churns constantly, but the next one or two blocks are usually a good estimate.
During heavy congestion (ordinals waves, exchange withdrawals after a price move, etc.) the queue can stretch to dozens of MvB. Most users wait it out; high-priority traffic pays the premium.
