Scale fast with Optimism, Ethereum's modular EVM L2

Optimism is a leading Layer 2 scaling solution for Ethereum, built as an EVM-equivalent Optimistic Rollup that batches transactions off-chain and posts compressed data back to Ethereum L1. Optimism delivers sub-$0.01 transaction fees, ~2-second block times, and full compatibility with Ethereum smart contracts, tooling, and JSON-RPC methods. Following the Bedrock architecture upgrade and the activation of Cannon-based permissionless fault proofs, OP Mainnet operates at Stage 1 decentralization.

What sets Optimism apart is the OP Stack – a modular, open-source codebase powering a growing network of Superchain L2s with shared security and standardized infrastructure. Optimism benefits DeFi protocols, NFT platforms, gaming dApps, payment applications, and rollup teams launching their own OP Stack chains, offering low fees, fast finality, EVM equivalence, and direct access to Ethereum's developer ecosystem and retroactive public goods funding (RetroPGF) model.
