Recently, I found that many people don't really know how to use Etherscan, but once you start interacting frequently with Ethereum, this tool becomes essential. Rather than calling it a block explorer, it's more like a window into understanding the on-chain world.

My own experience is that when I first started using Ethereum, I was stuck on one question: how do I confirm whether my transaction was truly successful? The information shown in my wallet was limited, and exchanges couldn't clarify it either. Later, I realized that the Etherscan platform can handle all these doubts. It’s basically Ethereum’s search engine—you can look up transactions, wallets, smart contracts—all on-chain data is public, and Etherscan just helps organize and display it.

The usage is actually very straightforward. Suppose you send a transaction, get the transaction ID, and paste it into Etherscan’s search box—you can see the complete transaction record. You will see the transaction hash, status, block number, timestamp, sender, receiver, amount, fee, and even gas price clearly. This is especially useful for beginners because you can see exactly how much gas you spent, whether the transaction was really on-chain, and if it was included in a block.

But Etherscan’s value goes beyond that. If you frequently interact with DApps or DeFi, you definitely need to verify smart contract addresses. For example, to add a new token to your wallet, you need to find the contract address on Etherscan to make sure you’re not scammed. I’ve seen many people lose funds because they pasted the wrong address, so this step really can’t be overlooked.

An advanced use is to interact directly with smart contracts on Etherscan. If a certain DApp is temporarily down or the website is inaccessible, you can bypass the front end using Etherscan’s Write Contract feature to communicate directly with the contract. After connecting MetaMask or other wallets, you can perform transfers, approvals, and other operations. This feature sounds advanced, but for most users, it’s not really necessary unless in an emergency.

Another underrated feature is gas tracking. Etherscan has a gas tracker that shows real-time network congestion and the confirmation speed for different gas prices. If you want a quick transaction, choose a high gas; if you want to save money, wait for low-traffic periods. This tool helps you make more precise decisions on when to act.

Many people don’t know that you don’t need to register an account to use most of Etherscan’s features. Only when you want to set up transaction alerts or access developer tools do you need to create an account. This openness makes it the most trusted Ethereum block explorer.

Finally, I want to say that Etherscan is not a wallet or an exchange. It’s simply an information platform. Actual transactions and asset management still rely on wallets like MetaMask or Trust Wallet. But if you want to deepen your understanding of the Ethereum ecosystem, track whale movements, or investigate suspicious transactions, Etherscan is currently the most powerful tool. Once you master it, your understanding of the on-chain world will reach a whole new level.
