Additionally, you may use Etherscan to directly communicate with smart contracts to conduct transactions, check gas prices, and look for airdrops.

Learning how to use the blockchain is really helpful if you use Ethereum for more than simply HODLing or sending a few transactions. Etherscan is one of the most widely used choices, making it a great place to start while learning the fundamentals. The majority of the functions may be used without connecting your wallet or even creating an account. Let's go over the most popular applications for Etherscan and what you can do with the data you discover.

You may access the public data on transactions, smart contracts, addresses, and other items on the Ethereum blockchain using Etherscan, a block explorer. Since every transaction made on Ethereum is visible to everyone, you may search through all of them using Etherscan. To inspect all associated activities, including tokens, smart contracts, and wallet addresses, you may utilize a transaction hash (transaction ID).

Etherscan doesn't need registration, although doing so gives you access to more features. For instance, you may use developer tools, set up data feeds, and establish alerts to be informed of incoming transactions.

Etherscan doesn't provide you with an Ethereum wallet to use or store any of your private keys. You also can't use it for trading. It only acts as a source of blockchain information and a database of smart contracts. To make transactions or store crypto, you'll need a crypto wallet such as Trust Wallet, MetaMask, Math Wallet, or Binance Chain Wallet.

Why should I use Etherscan?

One of the most dependable and well-known block explorers for Ethereum is Etherscan. It's more crucial to comprehend why you should inspect on-chain data using a block explorer like Etherscan.

How to look up a transaction and wallet on Etherscan?

A basic feature of Etherscan is tracking transactions. Understanding how to follow your cryptocurrency is a key to unlocking all the rest of a blockchain's information. For example, imagine you’ve sent 0.025 ether (ETH) from your wallet to the following public address: 0x480bbcb368197d44c6f54a738e59c33eff004b6a.

You also paid a 0.001559212674537 ETH transaction fee on top. After making the transaction, your wallet displays this TXID:


Let's say you want to check the number of confirmations the transaction has and see if it has been sent successfully. 

1. Head to the Etherscan homepage and look for the search field at the top of the page.

2. Next, copy and paste the transaction ID (TXID) into the search field and press the search icon.

3. Now you can see all the details regarding your specific transaction:

4. You can also press the [Click to see More] button for more detailed information, but for now, let’s go through just the default display:

Transaction Hash

The string of numbers and letters (TXID) associated with your particular transaction.


Whether your transaction has failed, is in progress, or was successful.


The block number your transaction was included in. You can also see how many times your transaction has been confirmed. This is the number of blocks added to the chain after your transaction's block.


The timestamp of the block your transaction was added to.


The wallet address that made the transaction..


The receiving address or smart contract.


The amount sent in the transaction.

Transaction Fee

The fee paid for making the transaction.

Gas Price

TXN Type

Information on whether a transaction was conducted under the old legacy gas system (1) or the new EIP-1559 block fee system (2).

From the data above, it's simple to see the transaction was successful and received enough confirmations. You could also check the status of your transaction by taking a look at the receiving wallet.

For this, you’ll need to go back to the search bar and paste the receiving wallet address:


The transaction in red is the 0.025 ETH you originally sent. You can see it marked as In, showing that the address you searched was on the receiving end. At the top of the page, you can also see an overview of the wallet's balance.

How to look up smart contracts on Etherscan?

It's a good idea to understand how to locate smart contracts on Etherscan if you frequently interact with them in DApps. By doing this, you can be sure that your money is going to the right contract.

You'll need to locate the token's contract address if you ever need to add a new token to your wallet. The token's functionality, including how transfers between tokens work and other actions, is included in the smart contract address.

Visit CoinMarketCap, CoinGecko, or the project's official website to locate a token address. You might also look https://etherscan.io/tokens

Always make sure you're adding the correct token address by double-checking it with the websites mentioned above. Let's take a look at the Uniswap ERC-20 token on Ethereum:


1. Copy and paste the smart contract address into the search field.

2. You'll now see details on the contract balance and other general information regarding the Uniswap (UNI) token contract.

3. Underneath, we have more options to look at, including transactions, a comments section, and the smart contract itself. Click [Contract] next to see the options available for interacting with and reading Uniswap’s rules.

4. The [Read Contract] tab shows you general contract information. It allows you, for example, to query the balance of specific addresses or wallets that have permission to use the token in your wallet.

Clicking [Write Contract] allows you to interact with the contract directly. This is useful when DeFi platforms and DApps are unavailable, perhaps due to a technical issue or website outage. In some cases, you can try to interact with the smart contract instead, without using the project’s API.

Clicking [Connect to Web3] will allow you to connect a crypto wallet like MetaMask or Binance Chain Wallet and interact with the contract.

The simplest action here would be a transfer of coins. Using [transferFrom], you can transfer tokens from an address you have permission over to other addresses.

[transfer] lets you transfer the contract’s associated token from your connected wallet. The transaction below would send 1 UNI from our connected wallet to the receiving wallet address pasted in. You also have to make sure to include the correct amount of decimals for the amount you want to send.

Most users won’t ever need to use these features. However, it’s still useful to know where they are in case you need to access funds stored in a smart contract.

How to check gas prices on Etherscan?

The transaction costs for Ethereum include gas expenses. Depending on the block that your transaction is a part of, these fees vary. The set cost for each block varies according to the network traffic. You can see the price and time differences at various gas prices with the Etherscan gas tracker. It's a helpful tool to estimate how crowded the network is and how much you'd probably have to spend to conduct a straightforward transfer or engage with a more complex smart contract.
