Fast, stable, scalable Ethereum.
OP Mainnet is a fast, stable, and scalable L2 blockchain built by Ethereum developers, for Ethereum
developers. Built as a minimal extension to existing Ethereum software, OP Mainnet's EVM-equivalent
architecture scales your Ethereum apps without surprises. If it works on Ethereum, it works on OP
Mainnet at a fraction of the cost.
OP Mainnet goes Superchain
The Superchain project seeks to maximize interoperability and composability between different chains
using the OP Stack, and integrate siloed L2s into a single, cohesive layer.
The Superchain
Building towards a unified future that doesn’t fracture our ecosystems, our applications, or our
ability to work together.
