THE SUPERCHAIN

Many chains.
One shared direction.

The Superchain brings OP Stack chains into a broader Ethereum-aligned ecosystem built around shared open-source infrastructure, standards and an expanding interoperability layer.

THE INFRASTRUCTURE

Different chains.
Shared foundations.

The OP Stack is an open-source modular stack for building Ethereum Layer 2 chains with configurable infrastructure.

Every chain has different requirements. Operators can configure data availability, fee logic, gas token rules, throughput and bridges without presenting every OP Stack chain as identical.
