There is no fixed number — it depends on how full recent blocks are. Use the three tiers at the top of this page: slow is fine for transfers that can wait, average targets the next few blocks, and fast is for time-sensitive trades. All three come from live on-chain fee history, not a cached daily average.
Estimates are produced before your transaction is included. If the base fee rises between the moment your wallet quotes you and the block your transaction lands in, you pay the higher base fee, up to your max fee. Anything above base fee plus tip is refunded to you automatically.
Gas is usually lowest between roughly 00:00 and 06:00 UTC and on weekends, when US and European activity bottoms out. That is a tendency, not a guarantee — a single large mint can invert it, so check the live figures above before assuming.
Nowhere. EIP-1559 destroys the base fee portion of every transaction, permanently reducing ETH supply. Only the priority fee reaches the validator. This is why periods of heavy network usage are described as deflationary for ETH.
Gwei is a denomination of ETH used for pricing gas: 1 gwei is 0.000000001 ETH. Quoting fees in gwei keeps the numbers readable — 25 gwei is far easier to reason about than 0.000000025 ETH.
Yes, if your wallet supports replacement. Resend the same nonce with a higher max fee and priority fee; most wallets expose this as "Speed up". You can also cancel a pending transaction by sending a zero-value transaction to yourself with the same nonce and a higher fee.
Rollups execute transactions off Ethereum and post compressed data back to it. Thousands of users share the cost of a single L1 settlement, and since EIP-4844 that data goes into blobs, which are priced separately and are far cheaper. Security still comes from Ethereum.
No. This page reads public on-chain fee history through a public RPC endpoint. There is no sign-up, no wallet connection, and nothing about you is stored.

Try ZestWhat is the base fee?
EIP-1559 introduced a dynamic base fee that adjusts per block. It is burned (not paid to miners) and changes based on how full the previous block was.
What is the priority fee?
Also called a "tip", this goes directly to the validator. Higher tips incentivise faster inclusion. Most wallets handle this automatically.
What is max fee?
The maximum you're willing to pay per gas unit. You're charged baseFee + tip, never more than maxFee. Any unspent amount is refunded.
Every Ethereum transaction consumes gas, a unit that measures computational work. A plain ETH transfer costs 21,000 gas, an ERC-20 token transfer usually lands around 65,000, and a DEX swap often exceeds 150,000. What you pay is that gas amount multiplied by a price per unit, quoted in gwei.
Since EIP-1559 went live in August 2021, the price per unit has two parts. The base fee is set by the protocol itself and burned — removed from circulation permanently. The priority fee, or tip, goes to the validator that includes your transaction. Your wallet also sets a max fee, the ceiling you agree to; anything above base fee plus tip is refunded.
The base fee moves algorithmically: it rises by up to 12.5% when the previous block was more than half full, and falls by the same proportion when it was emptier. That feedback loop is why Ethereum gas can double within a few blocks during a busy mint or a liquidation cascade, then settle just as quickly.
Base fee is a direct reading of demand for blockspace, nothing more. A handful of recurring patterns explain most of the swings you will see on this tracker.
Ethereum does not hand out a discount for patience — you have to take it. Timing and routing are the two levers that actually move the number.
