FAQ Section
1. Why add Optimism to MetaMask?
Optimism is a Layer 2 scaling solution for Ethereum, offering faster/cheaper transactions. Adding it lets you interact with Optimism-based dApps directly.
2. Can I use the same address for Ethereum and Optimism?
Yes! Your Ethereum address works across both networks, but ensure you’re on the correct network when transacting.
3. What if I send OP to the wrong network?
Funds sent to unsupported networks (e.g., Ethereum mainnet) may be lost. Double-check the destination network.
Troubleshooting Tips
- Network not appearing? Clear your browser cache or restart MetaMask.
- Transaction delays? Adjust gas fees or check Optimism’s status page.
