Blockchain explorers are tools that allow you to see everything that happens inside the blockchain. They are like X-rays: they show transactions, balances, smart contracts, and much more.
What you can do with the explorer:
Check the transaction. Enter its hash and see the status, fees, sender, and recipient.
Check the balance of any address. No logins, no passwords — everything is public.
Analyze smart contract activity. You can track how many people interact with the project and how often.
Learn about the token. Token contract, holders, circulating supply, wallet movements.
Track 'whale' movements. Who transfers large amounts and where.
How to get started:
1. Go to etherscan.io or bscscan.com — depending on the network.
2. Enter the address, hash, or token name in the search bar.
3. Analyze the data — everything is intuitive.
For DeFi, trading, and simply observing network activity — this is one of the most useful skills. With experience, you will learn to recognize suspicious activity, monitor 'insider movements', and act faster than others.
