Summary

Currently it shows that Loopring (see image) cost 0.39 dollar cent for each swaps. Which is not the problem, but swapping through orderbook on the platform can cost the end user nothing. They could even earn additional money by using this feature.

What I expect

Would be nice if we could optionally show additional information within the Swap Token column for each Protocol. Just like how l2Beat.com shows more information for each protocol.

So in this case for Loopring, the swap cell will be seperated in two different columns:
|$0.39 / $-0.20(through orderbook)|

Not an issue,

Just want to say thank you very much for this project!

For example zkSync uses about 400 L1 gas per transaction and optimistic rollups use about 4000 L1 gas per transaction. It could be interesting to know for people who are choosing a rollup or just starting out their research

sources: https://zksync.io/faq/tokens.html
" for every zkSync block, the validator must pay Ethereum gas to verify the SNARK, plus additionally ~0.4k gas per transaction to publish the state"

"l1GasUsed is calculated as 1.5*(2750 gas + calldataGas)"

Hi, starting a discussion.

Today, L2fees.info sorts L2 tx fees by Send ETH. It seems like L2s relative rankings on fees to Send ETH vs fees to Swap Tokens vary quite a bit.

What are thoughts on sorting by 'Swap Tokens' instead? By a rough estimate, Optimism and Arbitrum both do 8x the amount of transactions for DEX trades than for ETH transfers: https://dune.com/queries/2617904

L2Fees currently uses real-time prices. However, rollup prices fluctuate quite heavily with time (since L1 fees fluctuate heavily) and it's likely that the price that the user will pay by the time they execute a transaction is quite different than the price displayed by L2Fees.

There's also the issue of accurate comparison: L2 prices update at different rates and I'll often see one network with a much higher cost than another for a few minutes and then refresh the page to see that the rates have equalized. A user who views the page during this time window might have a very unrealistic view of the average costs of different networks. Since L2Fees is mainly being used to compare overall costs (not for estimating real-time costs), I think it makes more sense to use a rolling average over some short time window (maybe 24 hours?).

Since this project is so web3 it could be a good idea to install GitPOAP!
form here: https://www.gitpoap.io/#suggest

Recognize, nurture, and grow your community of contributors through the distribution of GitPOAPs & help them build an unbiased record of their work.

Is there any API available for this like for cryptofees? (for example https://cryptofees.info/api/v1/fees)

Hi, I was looking at the Optimism fees adapters & they reference subgrapghs that don't seem to be public. I wanted to make sure the appropriate changes got in before Bedrock migration on June 6.

L2 Transaction Fees:

• Formula does not change
• If the fee vault address is used, there will now be 3 fee vault addresses (1 previously). Withdrawals will come out of these 3 addresses as well on L2:
  • 0x4200000000000000000000000000000000000011: SequencerFeeVault
  • 0x4200000000000000000000000000000000000019: BaseFeeVault
  • 0x420000000000000000000000000000000000001a: L1FeeVault

L1 Data Costs

• The addresses that data is posted to on L1 are changing. Rather than CanonicalTransactionChain and StateCommitmentChain contracts, there is now BatchInbox and OutputOracle:
• L1 BatchInbox from address: 0x7431310e026B69BFC676C0013E12A1A11411EEc9
• L1 BatchInbox to address: 0xFF00000000000000000000000000000000000010
• L2 OutputOracle contract: 0xdfe97868233d1aa22e815a266982f2cf17685a27

The formula to calculate costs per transaction should not change, but see https://www.optimism.io/bedrock-upgrade for more information!

Optimism 'One Day Security Costs' are only showing costs for the State Commitment Chain (SCC) Submitter, but it is missing fees payed by the Canonical Transaction Chain (CTC) Submitter (i.e. it shows $39k for June 2, 2022 when the actual value is 78.7 ETH ~$143k)

Adding costs paid by Canonical Transaction Chain 0x6887246668a3b87F54DeB3b94Ba47a6f63F32985 submissions would resolve the issue.

More of a question than an issue. But afak there is only WETH on Arbitrum, right?
