# Optimism

> Ethereum L2 and Superchain ecosystem focused on low-cost EVM execution and public-goods-aligned infrastructure.

- Chain ID: 10
- Ecosystem: superchain
- Supported protocols/dApps in registry: 9
- Last verified: 2026-06-02 by composewith (confidence: medium)

## Best for

- Superchain-aligned applications
- Low-cost EVM apps with Ethereum settlement assumptions
- Public-goods and governance-focused products

## Tradeoffs

- Sequencer and bridge assumptions differ from Ethereum mainnet
- Superchain-specific choices can affect cross-chain deployment strategy

## Build on Optimism

- [build an app on the OP Superchain (Optimism)](https://composewith.eth/intents/optimism-superchain-app) — zerodev, uniswap, chainlink, layerzero
