Blockchain Explorer & Web3 Block Explorer – Web3Lens

Scan blockchain networks, find block explorers, look up crypto addresses and transaction hashes on 700+ blockchains with Web3Lens.

Web3Lens is a multichain blockchain explorer that helps you look up cryptocurrency addresses, transactions, blocks, and other blockchain data from one convenient extension. ### ADDRESS AND TRANSACTION LOOKUP Enter or paste a blockchain address, transaction hash, block number, or ENS name. Web3Lens identifies the input, detects the relevant network, checks address validity, and directs you to the appropriate blockchain explorer. The extension supports a wide range of address formats and covers more than 700 blockchain networks. ### MULTICHAIN BLOCKCHAIN DATA View blockchain information directly inside the extension, including: - Wallet balances and token holdings - Recent transaction activity - Transaction details and decoded input data - Address balances across supported EVM networks - Network-specific blockchain information Data is displayed with its source and retrieval time. Unavailable information is clearly identified rather than estimated. ### SECURITY AND RISK CHECKS Access useful checks when investigating blockchain addresses and smart contracts: - Offline OFAC sanctions list screening - Reported scam address detection - Smart contract verification status - Contract ownership and upgradeability information - Token approval inspection The absence of reported risks does not guarantee that an address or contract is safe. ### BLOCKCHAIN TOOLS AND PRODUCTIVITY Web3Lens also includes: - Context menu shortcuts for address and transaction lookups - Address bar search using the `w3` keyword - Page scanning to identify blockchain addresses and transaction hashes - Batch lookup for up to 50 values with CSV export - Address validation and unit conversion - Hexadecimal, hash and timestamp utilities - Gas calculations and gas tracking - Calldata encoding and decoding - Raw transaction decoding and sender recovery - Saved labels, notes, favourite networks and preferred explorers - Light and dark themes ### PRIVACY Web3Lens does not require an account or wallet connection. It does not include advertisements, analytics, or remotely hosted executable code. Your saved labels, notes, and preferences are stored locally in your browser. When online lookups are enabled, requests are sent to web3lens.com to retrieve publicly available blockchain information. You can disable online lookups in settings to use the available offline features, including address detection, explorer links, local tools, and sanctions screening. ### LANGUAGE SUPPORT The extension interface supports 15 languages and follows your browser's language settings. You can also change the language manually in the extension settings.
