The <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>lication is self-contained and is neither sponsored nor administered by the Ethereum Foundation, which is a non-profit organization.<\/p>\n<p>The team behind Etherscan includes seasoned developers and industry professionals, who developed the Etherscan app to make the Ethereum blockchain more accessible to everyday users. <\/p>\n<p>Although Etherscan is a centralized platform, the app does make it easier for people to search through the Ethereum blockchain.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Is_Etherscan_a_wallet\"><\/span>Is Etherscan a wallet?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Etherscan is not an Ethereum wallet, nor is it a wallet service provider. Users don\u2019t receive an Etherscan wallet when they search the Ethereum blockchain on Etherscan.<\/p>\n<p>Etherscan.io is an independent Ethereum-based block explorer. The Etherscan app keeps track of blockchain transactions on the Ethereum network. The app then displays the results like a search engine.<\/p>\n<p>This allows users to find the details of transactions on the Ethereum blockchain, which may give someone peace of mind if their transferred funds have not yet appeared in their wallet.<\/p>\n<p>While Etherscan can track the activity on an Ethereum wallet address, users will need to link the app to an existing crypto wallet to do so.<\/p>\n<p>You may wonder \u2014 Is Etherscan free to use? Yes, Etherscan is completely free.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_Etherscan_used_for\"><\/span>What is Etherscan used for?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Etherscan allows users to view the assets held on any public Ethereum wallet address. Using Etherscan, enter any Ethereum address into the search box to see the current balance and transaction history of the wallet under consideration. Etherscan will also display any gas fees and smart contracts involving that address.<\/p>\n<p>Users can use Etherscan to:<\/p>\n<ul>\n<li>Calculate Ethereum gas fees with the Etherscan gas tracker<\/li>\n<li>Lookup and verify smart contracts<\/li>\n<li>View the crypto assets held in or associated with a public wallet address<\/li>\n<li>Observe live transactions taking place on the Ethereum blockchain<\/li>\n<li>Lookup a single transaction made from any Ethereum wallet<\/li>\n<li>Discover which smart contracts have a verified source code and security audit<\/li>\n<li>Keep track of how many smart contracts a user has authorized with their wallet <\/li>\n<li>Review and revoke access to a wallet for any decentralized applications (DApps)<\/li>\n<\/ul>\n<p>Users can view any transaction of the Ethereum blockchain on Etherscan. These transactions include failed and pending transactions. <\/p>\n<p>Etherscan can also keep track of the progress of an incoming transfer. One way to track a transaction using Etherscan is to look it up on Etherscan.io using its hash key. The hash provides users with an estimate of how long the transaction will take to confirm. The page refreshes once the transaction is complete.<\/p>\n<p>Etherscan also works as an analytics platform. Anyone can use Etherscan to analyze on-chain metrics like changes to Ether (ETH) gas costs, as well as keep track of their portfolio and monitor their transaction history for suspicious activity.<\/p>\n<p>Only information that is public on the Ethereum blockchain is displayed on Etherscan, so information like a user\u2019s private keys can\u2019t be viewed on the app. Etherscan doesn\u2019t store any private keys and is not involved in any of the transactions shown. The app also cannot be used to solve a transaction failure.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Do_users_need_an_account_to_use_Etherscan\"><\/span>Do users need an account to use Etherscan?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Users are not required to sign up for an account before using the Etherscan app. However, signing up for an Etherscan account does give users access to additional features. These features include the ability to track addresses and receive notifications whenever a transaction occurs. Developers may also sign up to gain free access to Etherscan\u2019s blockchain explorer data and application programming interfaces (APIs).<\/p>\n<p>Thus, users with accounts can add their addresses to the \u201cwatch list\u201d on the block explorer to monitor or track their investments. Users can also set alerts so that they\u2019re notified of every incoming transaction via email. Etherscan also provides API services for developers so that they can create decentralized applications.<\/p>\n<p>Etherscan provides the following information for all incoming and outgoing transactions: <\/p>\n<ul>\n<li>Transaction hash<\/li>\n<li>Number of blocks within which the transaction was recorded and the time at which the transaction was confirmed<\/li>\n<li>Sender and receiver addresses<\/li>\n<li>Gas fee<\/li>\n<li>Amount sent<\/li>\n<li>Total transaction fee<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"How_does_Etherscan_work\"><\/span>How does Etherscan work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>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 users to view all the transactions associated with that address. <\/p>\n<h3><span class=\"ez-toc-section\" id=\"Viewing_a_transaction_and_wallet_on_Etherscan\"><\/span>Viewing a transaction and wallet on Etherscan<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Exploring a wallet address on Etherscan under the \u201cTransactions\u201d tab will show a list of all ETH transactions (Txns), or transactions that have used gas (Gwei) associated with that specific wallet.<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/s3.cointelegraph.com\/uploads\/2022-01\/6c857c6b-8505-4f14-9943-2274f98f8875.png\"><\/figure>\n<p>Type the wallet address on Etherscan\u2019s homepage and click \u201cSearch\u201d to be redirected to a page that displays all of that wallet\u2019s information.

The sender and recipient addresses and the total transaction fee are shown as well.<\/p>\n<p>To explore and track a single transaction, users will need the transaction hash or transaction ID, or TxHash. A TxHash is a unique string of numbers that identifies a transaction on the blockchain.<\/p>\n<p>When users input the TxHash into the Etherscan search bar, a list of information on that transaction will be populated on the page. From here, users can go to the Transactions tab to review additional information about the said transaction. Such data includes whether the transaction status was successful, pending or failed, as well as the total amount that was transferred.<\/p>\n<p>The value of the transaction in ETH, as well as the USD value of ETH at the time of the transaction, can also be viewed. Etherscan also displays the timestamp for each transaction in addition to the transaction cost, denominated in USD.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_use_the_Etherscan_gas_tracker\"><\/span>How to use the Etherscan gas tracker?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>\u201cGas\u201d refers to the transaction fee associated with a transaction to be executed successfully on the Ethereum blockchain. Transaction costs on Ethereum are referred to as gas fees.<\/p>\n<p>Ethereum\u2019s network can get highly congested. When a considerable amount of traffic is running on Ethereum&#8217;s blockchain due to Ethereum\u2019s auction-based model, the average gas price goes up as users compete against one another and bid to have their transactions included in the next block. Consequently, transactions are delayed and some transactions fail. <\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/s3.cointelegraph.com\/uploads\/2022-01\/afc04353-7196-4e0e-a4d0-4cc8564a86df.png\"><\/figure>\n<p>Gas prices vary depending on the block that the user transaction has been included in, as well as the degree of network congestion. Moreover, users may not be able to discern an accurate estimate of the gas fees they\u2019ll be required to pay before initiating a transaction.<\/p>\n<p>To determine a transaction\u2019s gas fees with accuracy, it\u2019s best to use Etherscan\u2019s gas tracker. Etherscan\u2019s gas tracker does more than simply show users the difference in gas prices at various time intervals. It\u2019s also useful for estimating how congested the network is and what the transaction cost will be per transaction.<\/p>\n<p>The Etherscan gas tracker functions as an ETH gas calculator. It examines pending transactions on the Ethereum blockchain to determine how much gas a transaction will require. <\/p>\n<p>Users receive a gas fee estimate so they can adjust the timing of their transactions to avoid high network traffic. Doing so saves transaction costs and allows for cheaper and smoother transactions, without suffering the anxiety that comes with not knowing whether a transaction will fail or succeed.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_use_Etherscan_to_check_the_wallet_balance_and_history\"><\/span>How to use Etherscan to check the wallet balance and history?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>To see how the balance in a user\u2019s wallet has changed over time, look up the address of the wallet on Etherscan and select \u201cAnalytics.\u201d From here, users can see the data analytics of a user\u2019s wallet, such as the user\u2019s ETH balance, the entire transfer history, transactions and fees paid.<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/s3.cointelegraph.com\/uploads\/2022-01\/95c3bd36-6bd5-4e70-88d8-36f57333638a.png\"><\/figure>\n<h3><span class=\"ez-toc-section\" id=\"Using_Etherscan_to_review_smart_contracts_and_wallet_access\"><\/span>Using Etherscan to review smart contracts and wallet access<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Smart contracts can be read and edited without the need for special permissions by using the Etherscan app\u2019s \u201cRead Contract\u201d and \u201cWrite Contract\u201d features. These tabs provide real-time information on various tokens and smart contracts. Users may also use these features to initiate a token transfer and approve smart contract transactions.<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/s3.cointelegraph.com\/uploads\/2022-01\/4826d781-174a-4cd7-99ec-286dc5899efe.png\"><\/figure>\n<p>Removing a token\u2019s access to the user\u2019s wallet can be achieved using Etherscan\u2019s Token Approval Checker. When users interact with DApps to buy or swap tokens, they tap directly into a user\u2019s wallet with their permission. Therefore, DApps are an appealing target for scammers looking to gain access to users\u2019 Ethereum wallet addresses.<\/p>\n<p>If users see suspicious activity or believe that a DApp has been compromised, they can use Etherscan to revoke its access to a specific wallet address. The user\u2019s assets inside the wallet will not be lost, but users will need to reauthorize the tokens when they access the DApp the next time around.<\/p>\n<p>To use Etherscan to review a user\u2019s approved token list, look up the user\u2019s wallet address on Etherscan\u2019s Token Approval Checker. Doing so will provide users with a list of all approved smart contract interactions with that wallet. From there, users can connect their wallet to Etherscan and click \u201crevoke\u201d to ensure that the specific DApp no longer has access to the user\u2019s wallet.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_road_ahead\"><\/span>The road ahead<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Etherscan is one of the leading tools for accessing reliable Ethereum blockchain data. Etherscan can review smart contract code, track gas prices and monitor the Ethereum blockchain in real time.<\/p>\n<p>Finally, Etherscan is free and doesn\u2019t require a user to register to access all of its features. Overall, it\u2019s a great place to start for users who would like to learn the full range of functionalities of a blockchain, as well as their Ethereum wallet and what information they can garner from a blockchain explorer. <\/p>\n<\/div>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
