L2Fees.info aims to display an apples-to-apples comparison of the fees for users to take common actions on Ethereum scaling solutions. While fee comparisons across layer-1 blockchains must account for the security and decentralization tradeoffs made by various blockchains, L2Fees only compares chains that inherit Ethereum’s security.
As well-respected leaders in the layer-2 space, we’ve delegated the curation and classification of projects listed on L2Fees to L2Beat.com.
Recently, the Metis project adjusted their data-availabilty system, leading to community discussion around the security assumptions of the chain. L2Beat.com reclassified the project as an Optimistic Chain, and community members began pushing for the project to be reclassified on L2Fees as well:
The site was updated to move Metis to a newly created “All L2s” tab, however the Metis team has pushed back against this change.
In light of this discussion, I’d like to use this opportunity to engage with the community, and establish the following properties in relation to L2Fees.info:
- What qualifications are required for a project to be listed in the CryptoStats
l2-feescollection and on L2Fees.info
- How should L2Fees.info present data that is simple, accurate and informative
I’d like to share my current take on these questions, and invite the community to respond to them:
l2-fees collection collection includes protocols that fit L2Beat.com’s definition of “a chain that fully or partially derives its security from L1 Ethereum so that users do not have to rely on the honesty of L2 validators for the security of their funds”.
Given that data availability is currently the most expensive resource for rollups, many projects have moved their data off of Ethereum, such as Metis (classified by L2Beat as an “optimistic chain”), ImmutableX, DeverseFi and Sorare (all classified as Validiums).
Given that this is a significant change in the security assumptions of an L2, L2Fees should clearly differentiate these projects from full L2s. This is currently accomplished by having two tabs: “Rollups” and “All L2s”.
I look forward to seeing the community’s thoughts on this topic!
