Base fee
Tiers are computed the way Ethereum actually prices transactions since EIP-1559: the next block's base fee plus a priority fee taken from the 10th, 50th and 90th percentiles of what recent blocks accepted. The dollar figures assume a plain ETH transfer at 21,000 gas — a token transfer or a swap uses several times that, so multiply accordingly. Gas moves block to block; this refreshes every minute.

What these numbers mean
Every Ethereum transaction pays for the computation it uses. The price of that computation is quoted in gwei, a billionth of an ether. Since the EIP-1559 upgrade the fee has two parts: a base fee set by the protocol according to how full recent blocks were, and a priority fee you choose, which is the tip that persuades a validator to include you sooner.
The three tiers above are the base fee plus a priority fee drawn from what recent blocks actually accepted — the 10th percentile for Safe, the 50th for Standard, the 90th for Fast. That is how the network really prices urgency, so the tiers reflect observed behaviour rather than a rule of thumb.
How to use it
If your transaction is not time-sensitive, the Safe tier will usually confirm; it may simply take longer. Standard is the sensible default. Fast is worth paying when you are interacting with something where being late costs you — a liquidation, a mint, a narrow arbitrage.
The dollar figures assume a plain ETH transfer at 21,000 gas. That is the cheapest thing you can do. A token transfer typically uses two to three times as much, a decentralised-exchange swap often five to ten times, and a complex contract interaction more still. Multiply accordingly rather than assuming the quoted figure applies to what you are about to do.
Why gas spikes
The base fee rises when blocks are consistently more than half full and falls when they are not, so it responds to genuine congestion within a few blocks. Sharp spikes usually mean a popular mint, a liquidation cascade, or an airdrop claim — a burst of people all wanting the same block. Waiting an hour is frequently the cheapest optimisation available, and moving activity to a layer-2 network is the structural answer.
Where the data comes from
Directly from an Ethereum node over public JSON-RPC, refreshed every minute. We read the next block’s base fee and the priority-fee percentiles from recent blocks. If the node is unreachable this tool shows nothing rather than a stale or estimated figure. See our methodology.
Frequently asked questions
Why is my wallet quoting a different number? Wallets add their own buffer and sample at a different moment. Gas changes block to block, roughly every twelve seconds.
Is the base fee paid to validators? No — the base fee is burned. Only the priority fee goes to the validator.
Does this cover layer-2 networks? Not yet. These figures are Ethereum mainnet only.
