Etherscan is the most trusted tool for browsing all public data on the web Ethereum blockchain Sometimes called “Ethplorer”. These data include transaction data, wallet addresses, smart contract and more. The app is independent and is neither sponsored or managed by the non-profit Ethereum Foundation.
The team behind Etherscan includes experienced developers and industry professionals who developed the Etherscan application to make the Ethereum blockchain more accessible to everyday users.
Although Etherscan is a centralized platform, the app does make it easier for people to search through the Ethereum blockchain.
Is Etherscan a wallet?
Etherscan is not an Ethereum wallet nor a wallet service provider. Users will not receive an Etherscan wallet when they search the Ethereum blockchain on Etherscan.
Etherscan.io is a standalone Ethereum-based block explorer. The Etherscan application tracks blockchain transactions on the Ethereum network. The app then displays the results like a search engine.
This allows users to find details of transactions on the Ethereum blockchain, potentially giving someone some peace of mind if the funds they are transferring have not yet appeared in their wallets.
Although Etherscan can Ethereum wallet address, users need to link the app to an existing crypto wallet to do so.
You might be wondering — is Etherscan free to use? Yes, Etherscan is completely free.
What is Etherscan for?
Etherscan allows users to view assets held on any public Ethereum wallet address. Using Etherscan, enter any Ethereum address in the search box to see the current balance and transaction history of the wallet under consideration. Etherscan will also show any gas fees and smart contracts involving that address.
Users can use Etherscan to:
- Calculate Ethereum Gas Fees with Etherscan Gas Tracker
- Find and verify smart contracts
- View crypto assets held or associated with public wallet addresses
- Observe real-time transactions happening on the Ethereum blockchain
- Find a single transaction from any Ethereum wallet
- Discover which smart contracts have verified source code and security audits
- Track the number of smart contracts authorized by the user using the wallet
- Review and revoke access to any decentralized application (DApps) wallet
Users can view any transaction on the Ethereum blockchain on Etherscan. These transactions include failed and pending transactions.
Etherscan can also track the progress of incoming transfers. One way to track a transaction with Etherscan is to look it up on Etherscan.io using its hash key. The hash provides users with an estimate of how long it will take to confirm a transaction. The page refreshes after the transaction is completed.
Etherscan can also be used as an analysis platform. Anyone can use Etherscan to analyze on-chain metrics such as changes to Ether (Ethereum) gas costs, as well as track their portfolio and monitor their transaction history for suspicious activity.
Only information disclosed on the Ethereum blockchain will be displayed on Etherscan, so information such as user private keys cannot be viewed on the app. Etherscan does not store any private keys and does not participate in any transactions shown. The app also cannot be used to resolve transaction failures.
Do users need an account to use Etherscan?
Users do not need to register for an account before using the Etherscan application. However, registering for an Etherscan account does give users access to additional features. These features include the ability to track addresses and receive notifications as transactions occur. Developers can also sign up for free access to Etherscan’s blockchain browser data and application programming interface (API).
Therefore, users with accounts can add their addresses to a block explorer’s “watch list” to monitor or track their investments. Users can also set up alerts so they are notified via email of every incoming transaction. Etherscan also provides API services for developers so that they can create decentralized applications.
Etherscan provides the following information for all incoming and outgoing transactions:
- transaction hash
- The number of blocks in which the transaction was recorded and the time when the transaction was confirmed
- sender and receiver addresses
- Gas costs
- send amount
- total transaction fee
How does Etherscan work?
To use Etherscan, simply enter any public Ethereum wallet address into the search field at the top of the Etherscan.io homepage. Doing so will allow the user to see all transactions associated with that address.
View transactions and wallets on Etherscan
Exploring wallet addresses on Etherscan under the Transactions tab will show a list of all ETH transactions (Txns), or transactions using the gas (Gwei) associated with that particular wallet.
Type the wallet address on Etherscan’s home page and click “Search” to be redirected to a page that displays all information about that wallet. The data will include its ETH balance and value in USD, as well as an overview of the wallet’s transaction history.
Click on the wallet’s transactions tab, which will open a new page showing details of all transactions involving this address. Details include transaction ID, block height, and transaction confirmation time.
The block height refers to the block that contains the transaction. The sender and recipient addresses and total transaction fees are also shown.
To explore and track individual transactions, users will need the transaction hash or transaction ID, or TxHash. TxHash is a unique numeric string that identifies transactions on the blockchain.
When a user enters TxHash into the Etherscan search bar, the page will populate with a list of information about that transaction. From here, the user can go to the “Transactions” tab to view additional information about the said transaction. Such data includes whether the transaction status was successful, pending, or failed, and the total amount transferred.
You can also view the transaction value in ETH, and the dollar value of ETH at the time of the transaction. In addition to transaction costs, Etherscan also shows the timestamp of each transaction, denominated in USD.
How to use the Etherscan Gas Tracker?
“Gas” refers to the transaction fees associated with successfully executed transactions on the Ethereum blockchain. Transaction costs on Ethereum are called gas fees.
The Ethereum network can get very congested. When there is a lot of traffic running on Ethereum’s blockchain due to Ethereum’s auction-based model, the average gas price rises as users compete with each other and bid to have their transactions included in the next block. Therefore, transactions are delayed and some transactions fail.
The gas price depends on the block the user is transacting on and the level of network congestion. Additionally, users may not be able to accurately estimate the gas fee they will have to pay before starting a transaction.
To accurately determine the gas cost of a transaction, it is best to use Etherscan’s gas tracker. Etherscan’s gas tracker doesn’t just show users the difference in gas prices at different time intervals. It is also useful for estimating the congestion level of the network and the transaction cost per transaction.
Etherscan gas tracker works as an ETH gas calculator. It examines pending transactions on the Ethereum blockchain to determine how much gas the transaction requires.
Users receive gas fee estimates so they can adjust transaction times to avoid high network traffic. Doing so saves transaction costs and allows for cheaper and smoother transactions without the anxiety of not knowing whether a transaction will fail or succeed.
How to check wallet balance and history with Etherscan?
To see how the balance in a user’s wallet has changed over time, look up the wallet address on Etherscan and select “Analyze”. From here, the user can see the data analysis of the user’s wallet, such as the user’s ETH balance, the entire transfer history, transaction and paid fees.
Review smart contracts and wallet access with Etherscan
Smart contracts can be read and edited without special permissions by using the “Read Contracts” and “Write Contracts” functions of the Etherscan application. These tabs provide real-time information about various tokens and smart contracts. Users can also use these features to initiate token transfers and approve smart contract transactions.
A token’s access to a user’s wallet can be removed using Etherscan’s Token Approval Checker. When users interact with the DApp to buy or exchange tokens, they go directly to the user’s wallet with permission. As such, DApps are an attractive target for scammers looking to gain access to users’ Ethereum wallet addresses.
If users see suspicious activity or think the DApp has been compromised, they can use Etherscan to revoke their access to specific wallet addresses. The assets in the user’s wallet will not be lost, but the user needs to re-authorize the tokens the next time they access the DApp.
To use Etherscan to see a list of user-approved tokens, look up the user’s wallet address on Etherscan’s token approval checker. Doing so will provide the user with a list of all approved smart contract interactions with that wallet. From there, users can connect their wallets to Etherscan and click “revoke” to ensure that the particular DApp no longer has access to the user’s wallet.
road ahead
Etherscan is one of the leading tools for accessing reliable Ethereum blockchain data. Etherscan can view smart contract code, track gas prices and monitor the Ethereum blockchain in real time.
Finally, Etherscan is free and users can access all of its features without registration. Overall, this is a good starting point for users who want to understand the full capabilities of the blockchain, Ethereum wallets, and what information they can get from a blockchain explorer.
