About L2BEAT

L2BEAT is an analytics and research website about Ethereum layer two (L2) scaling. We provide a comparison of the various Ethereum L2 systems available today.

An important differentiator between L2BEAT and similar sites is that L2BEAT is committed to educating users and lists only projects that match our narrow definition of L2. We define layer two as a chain that fully or partially derives its security from layer one Ethereum so that users do not have to rely on the honesty of L2 validators for the security of their funds.

Because of our commitment to education we present various non-trivial metrics aside from Total Value Locked (TVL). We have carefully examined each L2 project to determine the inner workings of their technology as well as the associated risks. To learn about any of our listed projects visit their respective page on L2BEAT.

We have also compiled a list of Frequently Asked Questions that will help explain some of the decisions we made for our site. We hope you find L2BEAT a valuable resource.
