Optimism

Getting Started

1. Add Optimism (OP Mainnet) to your wallet and bridge ETH from Ethereum at app.optimism.io/bridge.
2. Explore the ecosystem at optimism.io/apps for DeFi protocols, NFTs, and governance tools.
3. Participate in governance by delegating your OP tokens to delegates or voting directly on protocol proposals.
4. Build on Optimism using standard Ethereum tools — the OP Stack provides full EVM equivalence.
