Getting Started:

When you first visit Etherscan, the most prominent feature is the search bar. This is your primary tool for querying the blockchain. You can enter:
‍

• Wallet addresses
  
  
• Smart contract addresses
  
  
• Transaction hashes
  
  
• Token or NFT identifiers
  
  

Below the search bar, you’ll find real-time updates on the latest blocks added to Ethereum. Clicking on any block ID reveals detailed information such as:
‍

• Number of transactions included
  
  
• The validator who mined or validated the block
  
  
• Rewards earned by the validator
  
  
• Gas fees paid to process the block
  
  

Similarly, recent transactions are listed with clickable transaction hashes that open pages showing:
‍

• Transaction status (successful, failed, or pending)
  
  
• The block containing the transaction
  
  
• Sender and recipient wallet addresses
  
  
• Tokens involved and their amounts
  
  
• Transaction value in ETH and USD
  ‍
• Gas fees paid
  ‍

Exploring Wallets: Tracking Balances, Transactions, and Tokens

Clicking on any wallet address gives you a comprehensive overview of that wallet’s activity:
‍

• Current ETH balance and USD equivalent
  
  
• Complete transaction history
  
  
• Holdings of fungible tokens and NFTs
  
  
• Historical balance trends via the Analytics tab
  
  

This makes it easy to monitor your own wallets or investigate others, providing transparency and insight into asset flows.
‍

Smart Contracts on Etherscan: 

Etherscan also supports smart contract exploration. You can search for contract addresses to see if they have been verified or audited. Verified contracts have their source code publicly available, enhancing trust. However, even verified contracts carry risk, so always exercise caution.
‍

Analytics and Metrics: 

Under the ‘Resources’ tab, Etherscan offers valuable network metrics such as:
‍

• Daily transaction counts
  
• Total unique Ethereum addresses
  
  

Additional tools are available under the ‘More’ tab, including features like the Gas Tracker, which provides live updates on gas prices to help you estimate transaction costs based on network congestion.
‍

Practical Uses of Etherscan:
‍

1. Checking Transaction Status

Paste your transaction ID into the search bar to see if it’s confirmed, pending, or failed.
‍

2. Investigating Wallets and ENS Names

Enter any wallet address or Ethereum Name Service (ENS) like vitalik.eth to view asset holdings and transaction history.
‍

3. Tracking NFTs
‍

After purchasing an NFT, input your wallet address and navigate to the “ERC-721 Txns” section to view your NFT activity. You can also explore entire NFT collections, view top holders, and browse individual NFTs through the inventory tab.
‍

4. Monitoring Gas Fees

Use the Gas Tracker under the ‘More’ tab to get real-time gas price estimates, helping you decide when to submit transactions at optimal costs.
