Gas Costs

This page provides an overview of typical gas costs for posting comments on different chains using the Ethereum Comments Protocol (ECP).

Please note that the figures on this page are provided as estimates to give a general idea of transaction costs. The actual figures will vary.

Base Network

Base is an Ethereum L2 that offers significantly lower gas costs compared to Ethereum mainnet. Here are estimated fees based on various L2 gas price:

Example transactions:

For example a postComment that replies to a comment, the transaction is initiated and paid by the author, it costs around 73,657 gas units, with a limit of 74,532 gas units on Base L2; 4,324 gas units on L1:

With a gas price of 0.002915116 Gwei on L2, the transaction fee on Base L2 is 0.000000218753205117 ETH.
With a gas price of 0.411140238 Gwei on L1, after adjustment the final L1 fee is 0.000000004034505905 ETH.

The user total paid for 0.000000218753205117 ETH for the transaction, and at the time of transaction, it was 0.000439 USD.
