OP Stack and OP Superchain
The modular, open-source framework for building Ethereum Layer 2 chains, forming the interconnected Superchain ecosystem.
What is OP Stack and OP Superchain?
The OP Stack is a standardized toolkit for deploying optimistic rollups, including components like op-node for sequencing and Bedrock for EVM execution, enabling chains with 100ms latency. Used by over 25 chains, it supports shared bridges and governance via the Optimism Collective, which holds 19% of OP tokens for funding.
The OP Superchain connects these chains via a unified communication layer, allowing atomic cross-chain swaps and shared liquidity pools exceeding $20 billion TVL in 2025. It emphasizes Ethereum-grade security through collective sequencer sets and fault-proof systems.
