What this list means

Main.net groups networks as OP Stack when source links and chain fields identify them as OP Stack L2 mainnets. This is an editorial category for lookup and discovery, not an official certification of Superchain status, security model, bridge behavior, sequencer status, or production reliability.

Before using an endpoint in production, open the source link for the specific network, verify the chain ID, and use dedicated RPC infrastructure where reliability or privacy matters.
