FAQ
What is Base?
A Coinbase-incubated Ethereum L2 built on the OP Stack; Basescan is its official explorer.
Can I move assets from Base back to Ethereum mainnet?
Yes, via the official bridge or third-party bridges. The official one is safer but has a waiting period; third-party ones are faster with more contract risk.
How do I reach the official Basescan site safely?
The “Visit official site” button on this page points to Basescan’s official address: basescan.org. Fake clones are common in crypto — verify the domain and bookmark this page or the official URL.
