About
What it answers, and for whom.
A layer 2 fee has two parts: the cost of executing the transaction on the layer 2, and a share of what the rollup pays to publish its data on Ethereum. This dashboard shows both for each covered layer 2, for an ETH transfer, a token transfer and a swap, so the cheapest chain for each action is plain to see.
Costs are shown two ways: the median that recent transactions of that kind actually paid and what the action would cost now according to the chain's own fee estimator. When the two disagree, the receipts are the measure and the gap is shown.
Use it to choose a chain for a payment or a trade, or to watch how layer 2 fees respond when Ethereum blob prices move. Each figure links to the blocks and receipts behind it.
Method
How it will be measured.
Every figure will be read at a block, kept with its source and its exact read, and open a receipt anyone can re-check.
How receipts work →- Fees paid are read from layer 2 receipts: gas_used times effective_gas_price, plus the l1Fee field and any operator fee on OP Stack chains. On Arbitrum the L1 part is already inside gas_used and is shown apart through gasUsedForL1.
- Transactions are classified by their call: plain ETH transfers, ERC-20 transfer calls (selector 0xa9059cbb) and swaps through known router contracts. The median of each class is taken over the last hour and over each day.
- Current costs come from each chain's own estimators, such as the OP Stack GasPriceOracle getL1Fee and Arbitrum's NodeInterface gasEstimateComponents, for a standard transfer and swap at the latest block.
- Fees are converted to USD with the Chainlink ETH/USD feed at the same block, and every figure keeps its gas-token value beside the USD one.

Questions
Questions people ask.
Which Ethereum layer 2 is cheapest?
The cheapest chain changes with demand on each layer 2 and with blob prices on Ethereum, and it can differ by action. The dashboard ranks chains by the median cost of each action over the last hour, so the answer is current and specific to what you want to do.
Why do layer 2 fees change when Ethereum is busy?
Part of every layer 2 fee pays for posting data to Ethereum. When a rollup posts its data in blobs, that part follows the blob base fee, which rises only when blob demand runs above its target. Execution on the layer 2 itself is priced by the chain's own base fee.
What is the L1 data fee?
On OP Stack chains it is the l1Fee in each receipt: the estimated cost of publishing that transaction's compressed bytes to Ethereum, computed from the Ethereum base fee, the blob base fee and the chain's fee scalars. Arbitrum charges the same cost as extra gas, recorded as gasUsedForL1.
Why does a swap cost more than a transfer?
A swap calls more contracts and changes more storage, so it uses more gas on the layer 2. Its calldata is also longer, which raises the data fee. The dashboard measures each action's median gas on each chain, so the difference is visible.
- L1 data fee
- The part of a layer 2 fee that pays for publishing the transaction's data to Ethereum.
- Effective gas price
- The price per unit of gas a transaction actually paid, recorded in its receipt: the base fee plus the tip.
- Operator fee
- An optional per-transaction fee that an OP Stack chain operator can set, paid into its own fee vault.
