The Optimism ecosystem powers one of the most efficient and fast-growing Layer 2 networks built on Ethereum. Designed around the Optimistic Rollup framework, it scales Ethereum by bundling transactions off-chain, reducing gas fees while maintaining mainnet-level security. Optimism is home to hundreds of DeFi, NFT, and infrastructure projects leveraging its low-cost and high-throughput environment. Its native token, OP, drives governance through the Optimism Collective - a community-led initiative shaping the future of public goods funding and open-source development. As developers continue to migrate to Optimism, it has become a central pillar of Ethereum’s scaling roadmap, promoting modularity, sustainability, and decentralization.
It’s a network of dApps, tokens, and protocols built on Optimism - a Layer 2 scaling solution for Ethereum using Optimistic Rollups.
Optimism batches multiple transactions off-chain, reducing congestion and gas costs while maintaining Ethereum’s security guarantees.
Notable projects include Uniswap, Synthetix, Velodrome, Lyra, and Perpetual Protocol.
The OP token supports governance through the Optimism Collective, funding public goods and incentivizing network participation.
While both are Layer 2 rollups, Optimism emphasizes public goods and modular governance, whereas Arbitrum prioritizes throughput optimization.
