Layer 2 networks
7 layer 2 networks with the facts we checked on each project’s own pages.
This directory lists every layer 2 network we have a profile for. Each card shows the chains, platforms and custody model stated by the project. For our ranked picks with pros, cons and who should skip each one, see Best Layer 2 Blockchains.

FAQ
Which layer 2 network ranks first on DappAtlas?
Base is #1 in our list “Best Layer 2 Blockchains” (updated Oct 1, 2026). Base is built by Coinbase, uses ETH for gas with no separate token, and publishes its node software under MIT. Each transaction pays an L2 execution fee plus an L1 security fee.
How is this directory ordered?
