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.
