Etherscan was developed in 2015 to be an open, searchable platform for access to blockchain data for the Ethereum Network through its search, API, and analytics functionality.
The first version of Etherscan was launched in August 2015 as an Ethereum block explorer by founder Matthew Tan, with API services launching in September 2015.
In April, smart contract verification was added to Etherscan, followed by the addition of support for the ERC-20 token standard in July.
Support for Ethereum Name Service (ENS) lookups were added in May, while Etherscan also became the first to include NFTs into their blockchain explorer by displaying CryptoKitties metadata in December.
The Gas Tracker was released by Etherscan in June and labels to contextualize on-chain addresses were added in October.
The Etherscan web3 search engine Blockscan was released, as well as BeaconScan for Ethereum's Beacon Chain; Explorer as a Service (EaaS) was also launched allowing users to deploy a full featured block explorer.
By May, Etherscan had become one of the top 1,000 most trafficked sites globally and added multichain transaction searching using Blockscan in July.
Etherscan supported Ethereum's Merge to Proof of Stake in September, and the Etherscan Chrome Extension was launched in November.
Etherscan's Metadata API was launched in April, while EaaS services were expanded to more than 20 clients by July.
In January, Etherscan acquired Solscan to expand their blockchain explorer capabilities, while Etherscan launched Blockscan Multichain Explorer that supports 30+ blockchains in July, and Etherscan API V2 that supports 50+ blockchains with a single API key in October.
Distributed blockchain indexing infrastructure supporting 30+ blockchains with real-time data updates and high-performance API access
Not a primary focus; platform focuses on data indexing, aggregation, and presentation of blockchain information

Etherscan is the most well known and trusted Ethereum block explorer with the best smart contract verification and analytics for DeFi, NFT and much more. While Blockchain.com has more multi-chain coverage it has far less Ethereum specific detail.
Use Etherscan for your Ethereum exploration needs. Use Blockchain.com for your multi-chain exploration needs.
Blockchair is great if you want to have the ability to search across multiple chains and also provide advanced reporting and analytics to the user. However Etherscan is the best choice for deep smart contract information and NFT tracking however it is primarily focused on Ethereum.
Use Etherscan for your public Ethereum exploration needs. Use Blockchair for your cross-chain data export and analytics needs.
Chainlens is an inexpensive option (typically 1/10th to 1/100th the cost of hosting your own explorer) that targets teams looking to create their own custom explorers. Etherscan is the current market leader with many of the best features available today including full support from the community to explore the blockchain directly.
Use Etherscan for public Ethereum exploration. Use Chainlens for private customized explorers.
Etherscan expanded its business model to include other chains by branding their explorers (Arbiscan, Basescan, Polygonscan) using the same underlying architecture and therefore created a network effect that helps maintain the company’s dominance within the EVM chain space.
Etherscan’s ecosystem currently captures the majority of the EVM chain exploration market.
Etherscan is a blockchain explorer for Ethereum that allows users to search through the transactions made by an address, as well as blocks, smart contracts and even find out the current balance of an account. Users simply enter the hash of a transaction, or the address of a contract or account into the search bar, and Etherscan will show the user up-to-date information about what happened to the transaction, including how much was spent in gas costs, whether the transaction went through or failed, etc.
No, Etherscan is a read-only explorer. What this means is that users cannot use Etherscan to send cryptocurrency from one wallet to another. If a user wants to make a transaction, then they will need to go to a wallet service such as MetaMask.
The basic explorer functionality of Etherscan is completely free. In order to get higher rate limits for your API usage, you would have to sign-up for the API Pro plan which is approximately $20/month.
Etherscan is currently the most widely used Ethereum explorer because of its high uptime, extensive token analytics and its verified contract database. Other Ethereum explorers may be able to handle more chains, but none of them can offer the quality and level of integration with the ecosystem that Etherscan offers.
Since Etherscan is a read-only explorer, users do not have to put in their private key in order to use it. Etherscan uses public blockchain information in order to generate the data that users see. Any API keys that users have to create in order to pay for Etherscan’s premium features should be stored securely by the users.
Yes, since users are able to upload the source code of the contract and the arguments passed into the constructor function to Etherscan, users are also able to confirm that the contract has been deployed properly. Contracts that are verified display a green checkmark next to them, allowing users to directly interact with the contract.
The Free tier: 5 requests/second, 100k requests/day. The Pro: 100 requests/sec, no limit on number of requests per day. The Enterprise: Custom limits and customized support.
Users are able to get live price data for gas via the Gas Tracker tool provided by Etherscan. Additionally, historical gas price charts are available to assist users with timing their transactions when gas prices are lowest, thus reducing the amount of money spent on gas to complete a transaction.

Etherscan is the gold-standard Ethereum blockchain explorer, supporting millions of daily searches each day through its reliability and comprehensive coverage of blockchain data. While there is a competitive landscape across all chains, there is no alternative that has reached the level of maturity and API capabilities as Etherscan has on the Ethereum ecosystem. This makes it an ideal solution for developers, traders, and project teams who require reliable blockchain visibility.
Etherscan is the primary infrastructure tool for Ethereum developers, traders and analysts.
Etherscan dominates the space of Ethereum exploration with comprehensive transaction/block/contract data and a robust free API tier, plus Pro and Enterprise upgrades. It supports most Ethereum dApp builds through the API and provides EaaS for custom/private chains. Etherscan has been the industry standard since 2015 and has unparalleled ecosystem integration.

The Etherscan group runs over 20 explorers that include BscScan, PolygonScan and Optimistic Etherscan. They have consistent interfaces across all EVM chains.
Branded block explorers are offered by EaaS to allow for private/custom blockchain UIs to be created for gaming/metaverse projects.
Users can now view and cancel ERC-20 approval scans to help avoid potential hacks. Over 10 million risky approvals have been revoked since its release.
CoinMarketCap uses Etherscan for portfolio tracking, DeFiLlama and Zapper.fi for their analytics. Etherscan is referenced on ethereum.org documentation as one of the recommended explorers.
