Currently, Linea’s mainnet is now live. I am interested in Linea and specifically researching about tx cost.
I checked the official documentation and as far as I can see, none of your resources disclose any information about gas & fee. (Through the docs, I learn only the execution fee in L1 → L2 bridge situation and Manual vs Automatic Claiming explanation)
Also i learn from the [Architecture of Linea - Coordinator chapter] that “Coordinator is Linea’s consensus client”
To get a realistic idea of how to use it, I looked for a TX that had actually used the bridge.
I have two feedbacks.
- your bridge L1 → L2 is still taking longer than expected…
- use “Manual claiming” to move assets from L1 → L2, the first users to use Linea(L2) will not have any ether to claim. This is a very terrible UX.
Back to the main body, To check the tx cost, i could find the commonly txn type on etherscan:
- ETH Transfer tx : 0x0cf00de98745d47a7314163a097305671dacef39a5f4f53ec07a2479aa91018a
- 0.00003678 ETH (1.751742395 gwei * 21,000)
- ERC-20 Transfer tx : 0x5fa46c04dd7c9f6324c3d2cc3993129735c89b8bad8051836616338993876927
- 0.00006909 ETH (1.426200394 gwei * 48,436)
tx Cost = gas Price * gas Used, which is the same as the tx cost normally calculated by L1, Linea is zk-Rollup, and from what I hear, zk-Rollup has a very expensive proof gen/verify cost, which is why the prover fee should be included in the tx cost, but I’m wondering why it’s so cheap and how the fomulas are currently defined.
Thank you for reading it
