Network Comparisons
Layer 1 vs Layer 2 Networks
A simple explanation of Layer 1 and Layer 2 networks, why they exist, and what users should check before moving assets.
Network map
What this means
A Layer 1 is a base blockchain, while a Layer 2 generally builds on top of a base chain to improve cost, speed, or scale.
Core ideas
What to understand first
- Ethereum and Bitcoin are examples of Layer 1 networks.
- Base, Arbitrum, and Optimism are Ethereum Layer 2 networks.
- Layer 2 assets are not automatically the same as mainnet assets.
- Bridges often connect Layer 1 and Layer 2 environments.
User checklist
What to check before moving assets
- Confirm whether your asset is on mainnet or an L2.
- Use the correct network in your wallet.
- Check bridge source and destination.
- Keep the right gas token on the right network.
Risk note
Common mistakes to avoid
- L1/L2 confusion causes missing balances and wrong deposits.
- Bridges introduce extra waiting and security assumptions.
- Token contract addresses differ across layers.
