What is Etherscan?
Etherscan is an independent block explorer and analytics platform for the Ethereum blockchain. Launched in August 2015, the platform indexes blocks, transactions, smart contracts, token balances, and gas metrics. It has indexed over 3.8 billion transactions as of October 2026.
Team and development
Etherscan was founded by CEO Matthew Tan as an independent infrastructure service dedicated to open access to blockchain records. The platform offers developer APIs and white-label explorer services known as Explorer as a Service (EaaS).
How data indexing and the API work
Etherscan provides onchain data through its explorers and APIs. In addition to raw block data, Etherscan maintains a metadata registry that assigns human-readable nametags and entity labels to addresses. Developers can query live data, verify smart contracts with tools like Foundry, or fetch contract ABIs using the Etherscan API across more than 60 supported networks. The service also operates Model Context Protocol (MCP) endpoints and plugins that allow AI coding tools to parse live on-chain states.
Pricing tiers and access
Public web exploration is free. The free developer API tier allows up to 3 calls per second and 100,000 daily calls across selected chains, with payload volume set to 1,000 records per request. Paid commercial plans scale through Lite, Standard, Advanced, Professional, and Pro Plus tiers, offering throughput between 5 and 30 requests per second, elevated daily limits of up to 1.5 million requests, and access to PRO endpoints such as real-time address metadata lookups.
Track record and operational trade-offs
Prescient Assurance audited Etherscan's explorer, APIs, and Explorer as a Service offering, and Etherscan completed a SOC 2 Type II examination in September 2026. The platform experienced an incident involving an injected pop-up within its comment section, which prompted the team to disable and patch the forum without compromising user funds. Key limitations involve API rate limiting for heavy data pipelines and the planned deprecation of networks such as ApeChain and Blast scheduled for late October 2026.

Our review

Very good
Etherscan is an Ethereum block explorer with metadata and developer APIs; its free API has lower limits and some metadata endpoints are paid.
Founded in 2015 by Matthew Tan, Etherscan is an Ethereum block explorer and analytics platform. It provides real-time transaction tracking, mempool feeds, verified smart contract code, and token statistics across more than 438 million tracked addresses. By October 2026, the service had indexed over 3.8 billion transactions.
For developers and compliance teams, the platform offers an API covering over 60 networks, with integrations extending into Model Context Protocol (MCP) servers and AI workflows. Free API plans allow up to 3 calls per second and 100,000 calls per day, though a July 2026 change lowered the free record retrieval limit from 10,000 to 1,000 per request. Higher throughput, ranging between 5 and 30 calls per second, requires paid plans like Standard, Advanced, or Pro Plus.
Regarding operational security, Etherscan completed an independent SOC 2 Type II audit evaluated by Prescient Assurance LLC in September 2026. A past vulnerability involving an injected popup in the website comment section was resolved by disabling and patching the feature, with no user funds compromised.

What users say about Etherscan
Users widely rely on Etherscan as the standard tool for verifying blockchain transactions and tracking on-chain wallet activity.
In their own words
“If you received the payment, great. If not, copy and paste the Ethereum address you gave them into Etherscan: At the top of the site, it should say “The Ethereum Blockchain Explorer.” Paste your wallet address into the search bar.”
“Since the Coinbase or Kiln app interface might be lagging, the "source of truth" is the blockchain itself. Copy the wallet address. Go to Etherscan.io (or the relevant explorer if it was staked on Base). Look under the "ERC-20 Token Transfers" or Internal Transactions tabs.”
“Ether not showing up in dashboard? Recently, I sent a transaction from Coinbase to Kraken on the ETH network, waited for it to go through, and then checked kraken. It never showed up.”
