What is Optimism?
A multi-chain ecosystem built on the open-source OP Stack framework , enabling faster and lower-cost Ethereum transactions across a growing network of L2 chains.
Optimism is a network of multiple blockchain chains built on the open-source OP Stack framework. OP Mainnet was the first chain launched, and the ecosystem has since expanded to include Base (Coinbase), Unichain (Uniswap), Ink (Kraken), and World Chain (Worldcoin). The OP Stack has emerged as a widely adopted framework for Ethereum Layer 2 scaling solutions, currently processing a significant portion of Layer 2 transaction volume.
Chains on the OP Stack participate in a revenue-sharing model with the Optimism Collective, contributing the greater of either 2.5% of total chain revenue or 15% of onchain profit. This creates economic alignment across multiple chains while enabling faster and lower-cost transactions on Ethereum. OP token holders exercise governance rights over protocol upgrades and funding allocation decisions.
OP Stack Framework
OP Mainnet is the first chain built on the open-source OP Stack, which has become a widely adopted standard for Ethereum Layer 2 scaling solutions and a reference architecture for the broader L2 ecosystem.
Multi-Chain Ecosystem
The OP ecosystem includes Base (Coinbase), Unichain (Uniswap), Ink (Kraken), and World Chain (Worldcoin), reflecting broad institutional adoption of the OP Stack across major crypto companies.
Revenue Sharing Model
Chains on the OP Stack contribute the greater of 2.5% of total chain revenue or 15% of onchain profit to the Optimism Collective, creating economic alignment and sustainability across the ecosystem.
Ethereum L2 Scaling
The OP Stack processes a significant portion of Ethereum Layer 2 transaction volume, enabling faster transactions and substantially lower costs compared to executing directly on Ethereum mainnet.
OP Token Governance
OP token holders exercise governance rights over protocol upgrades and funding allocation decisions within the Optimism ecosystem, shaping the direction of the OP Stack and the Optimism Collective.
Economic Alignment
The revenue-sharing model is designed to create sustainable economic alignment across multiple chains while funding public goods and long-term development within the Optimism Collective.
Ecosystem Growth & Institutional Adoption
The OP Stack has attracted major institutional operators and processes a significant and growing share of Ethereum Layer 2 activity.
L2 Transaction Volume
The OP Stack currently processes a significant portion of all Ethereum Layer 2 transaction volume, reflecting broad adoption of OP Mainnet and its affiliated chains across the DeFi ecosystem.
Institutional Chain Operators
Coinbase, Uniswap, Kraken, and Worldcoin have each deployed their own chains on the OP Stack, reflecting strong institutional confidence in the framework as a production-grade L2 infrastructure.
Ecosystem Development
The Optimism Collective funds and coordinates ecosystem development, directing resources toward protocol improvements, developer tooling, and public goods within the broader OP Stack ecosystem.
