What a transaction actually costs right now, in pounds and pence, on sixteen chains at once. Reads the current gas price from each chain and converts it using the live price of that chain’s coin, so a swap on Ethereum and a swap on Base are compared like for like rather than in gwei that mean nothing across chains.
A transaction fee is the gas price multiplied by how much work the transaction does, priced in whatever coin the chain runs on. Three things move independently: how busy the chain is, how complex the action is, and what the native coin is worth. That last one is why a chain can get cheaper in dollars while getting busier, and why comparing gas prices in gwei across chains tells you almost nothing on its own.
This reads the current gas price from each chain directly and converts it to what you would actually pay, so the comparison is like for like. Gas units are the conventional estimate for each action rather than a promise: a swap routed through several pools costs more than a single hop, and a first time token approval costs more than a repeat.
Three things move at once. How busy the chain is sets the gas price. How complex your action is sets how much gas it uses. And the value of the chain’s native coin converts that into money. A chain can have a gas price a thousand times higher in gwei and still be cheaper, because its coin is worth a fraction as much. That is why comparing gwei across chains is meaningless and why this page converts everything into what you would actually pay.
They are a close comparison rather than a quote. The gas price is read live from each chain, and the coin prices are live. What is estimated is how much gas each action uses, and that varies: a swap routed through several pools costs more than a single hop, and a first approval costs more than a repeat. Your wallet will show the real figure before you sign, and that is the number that counts.
On busy chains, fees fall noticeably when Europe and the United States are both asleep, roughly the early hours UK time, and rise through the American afternoon. Weekends are usually quieter than weekdays. If a transaction is not urgent, waiting for a quiet window on an expensive chain can save a meaningful amount. On chains that are already fractions of a penny it makes no practical difference.
Because you are paying for computation, not for value. Sending ten pounds and sending ten thousand pounds cost exactly the same, which is why small transactions can lose a large percentage to fees and large ones barely notice. It is also why bridging a small amount is usually a bad idea.
No. It reads public data from each chain and from a price feed. There is no wallet connection, no sign up, and nothing to enter.
We seal the list every week and keep re-checking every token on it, so you can see what actually happened to them rather than only what is trading today.
