What this means
Base can be used with MetaMask as an EVM-compatible Layer 2 network, but Base assets remain separate from Ethereum mainnet assets.
Core ideas
What to understand first

- Base is an Ethereum Layer 2 network.
- Wallet addresses may look the same across EVM chains.
- Base tokens have Base-specific contract addresses.
User checklist
What to check before moving assets
- Add or select Base from trusted wallet settings.
- Keep ETH on Base for gas.
- Verify token contracts on a Base explorer.
- Check bridge direction before moving assets.
Risk note
Common mistakes to avoid
- Base and Ethereum mainnet assets are often confused.
- Fake bridge pages can request malicious signatures.
- Wrong-network exchange deposits may require support.
