Etherscan Overview

Launched in 2015, Etherscan has now become the leading block explorer for the Ethereum blockchain. Transactions on a blockchain are public and take place continuously. A block explorer like Etherscan is a search engine that helps users to look up, confirm and even validate the transactions that have already taken place on the Ethereum blockchain.

How Does Etherscan Work?

Etherscan is an independently operated organization that is non-funded and free for everyone to use. The company indexes the public ledger of the Ethereum blockchain to make all the transaction-related information available on the Etherscan platform.

To get started with a search, you have to enter the wallet address in the search criteria. A crypto wallet helps you to store crypto and make transactions through it. Each user has a unique wallet address that they need to use to search for the relevant transactions on Etherscan.

Building Wealth

Etherscan aims to make blockchain technology and transactions easily accessible to all its users by providing this free-of-cost service. However, it must be remembered that Etherscan is simply a platform that shows all the transactions and their status. You cannot get wallet services on the Etherscan platform because they do not store private keys and have no control over the transactions that occur.

Useful Features of Etherscan

Etherscan helps in making blockchain transactions more transparent to its users. In the context of token-related blockchain transactions, here are some useful features that Etherscan provides.

Check Token Balance

This a helpful tool that allows a user to check how the token balance on a given wallet address. This option is available under the “ETH Account Balance Checker” tab on the Etherscan platform. The user needs to enter the address and then specify the date or block to generate the current token balance. This option also shows if there are any quantity changes as of that date.

Etherscan allows its users to check the status of ERC20, ERC721 and ERC1155 tokens.

Validate Transactions

With the help of the “EthValidate”, Etherscan allows its users to validate the account balances, transactions and token balances on the Etherscan’s node with other nodes on the Ethereum blockchain.

Users can navigate to the “Validate Account Balance” option which gives them insight into the validation details of an address. Information from other Ethereum nodes like Infura, Chainstack MyEtherWallet, and MyCrypto is also displayed as a part of the validation results.

Signature Verification

The unique wallet address of a user is often used put an exclusive signature on a message to verify the ownership of the address. When a wallet address is signed, it generates a unique signature hash that acts as proof that the message was indeed signed by the original owner.

Etherscan uses a UI enhancement technique to sign and publish a message directly on its platform. Once you click on the “Sign Message” button, you will be prompted to connect to the Etherscan website through MetaMask or WalletConnect and then enter the message that you want to sign. Etherscan also allows you to publish the signed message on external websites and verify the messages that have been written by a message.

Gas Tracker

Ethereum is an independent blockchain that is not overseen by any centralized authority. To protect the network from congestion, a mechanism exists within the blockchain, which charges a small fee called “gas” to do this job. The user has to pay this gas fee in Ether tokens and gets reduced from the token balance while they are making a transaction.

Building Wealth

Since the number of gas fees is not fixed, users are often confused about how much to charge. Etherscan helps the users in proposing a recommended gas price for a transaction depending on the network traffic and the existing average gas fee. This feature is known as Gas Tracker and is available on the Etherscan platform.

Etherscan and Smart Contracts

Smart contracts are self-executing contracts that exist on the Ethereum blockchain and are fulfilled when the underlying conditions are met. Smart contracts are an important element in the crypto space and Etherscan allows you to search for smart contract source codes on the platform.

You can also use filters to sort them by contract and deployer addresses, creation dates, block numbers and more. This is a relatively new feature introduced by Etherscan and will help the users to gain insights into the technical details of smart contracts.

Etherscan and Dapps

Decentralized applications or dapps are applications that exist on the Ethereum blockchain and play an important role in the cryptocurrency ecosystem. These applications have underlying smart contracts that facilitate interactions between users. Given the versatility of blockchains, the scope of dApps is huge and it has already spread into gaming and finance widely.

Most dapps exist on the Ethereum blockchain which is why they are available on the Etherscan platform. Etherscan acts as a database of different types of dapps and they are categorized according to the sector to which they belong. When you click on them, you will be directed to the dapp page set up by Etherscan that gives the developer a personalized front-end view of the dapp. The developer can also interact with the underlying smart contract and customize their dapp page with banner images, social links, etc.

Etherscan and DEX

DeFi or decentralized finance is another decentralized application hosted mostly on the Ethereum blockchain. It enables users to conduct financial transactions like trading, lending and borrowing independently and they take place on various decentralized exchanges.

Etherscan allows users to track activities on decentralized exchanges like Uniswap V2, Unisaw V3, SushiSwap, Bancor Network, Ether Delta and Airswap V2.

Etherscan and NFTs

NFTs or Non-Fungible Tokens can be tracked using the Etherscan platform. Etherscan allows you to track them from popular NFT marketplaces like OpenSea, LooksRare, 0x Protocol, Rarible, SuperRare and X2Y2. Apart from the transactions, Etherscan also has a page to track the NFTs that are being minted on these marketplaces.

Etherscan is a free platform and you do not need to create an account to access the basic features. You do need your wallet address so that you can track the transactions or view the token balance in your account.
