Navigating the vast and complex landscape of Web3 and blockchain technology requires the right tools. A blockchain explorer is an essential utility for anyone interacting with cryptocurrencies, decentralized applications (dApps), or any on-chain activity. It acts as a search engine for a blockchain, allowing you to view transactions, check wallet balances, verify contract interactions, and explore network statistics.
This guide compiles a comprehensive list of reliable and widely-used blockchain explorers for various major networks. Whether you are a developer, investor, researcher, or enthusiast, having these tools bookmarked will significantly enhance your Web3 experience.
Why You Need a Blockchain Explorer
Before diving into the list, it's crucial to understand the core functions of a blockchain explorer. These platforms provide transparency into the immutable ledger of a blockchain. You can use them to:
- Verify Transactions: Confirm the status (pending, confirmed, failed) and details of any transaction.
- Check Wallet Addresses: View the balance and transaction history of any public address.
- Analyze Smart Contracts: Examine contract code, storage, and interaction history.
- Monitor Network Health: Track metrics like gas fees, block times, and network hash rate.
- Investigate Tokens: Get information about token contracts, holders, and transfers.
Comprehensive List of Blockchain Explorers by Network
Here is a curated directory of official and popular block explorers for a wide array of blockchain ecosystems.
Multi-Chain Explorers
These explorers support multiple blockchains from a single interface, making them incredibly versatile.
- OKLink: A leading multi-chain blockchain explorer providing data for Bitcoin, Ethereum, Liteton, and more. It offers detailed information on blocks, transactions, and key network metrics.
- Blockchain.com Explorer: A well-known explorer that provides data for the Bitcoin and Ethereum blockchains, offering a clean interface and robust data coverage.
Ethereum and Ethereum Virtual Machine (EVM) Networks
The Ethereum ecosystem, including its Layer 2 scaling solutions and compatible chains, is home to a massive portion of Web3 activity.
- Etherscan: The definitive and most widely used block explorer for the Ethereum mainnet. It is the industry standard for checking ETH transactions, gas prices, and smart contract interactions.
- BscScan: The official block explorer for the BNB Smart Chain (BSC), essential for anyone using the Binance ecosystem of dApps and tokens.
- PolygonScan: The official explorer for the Polygon network, allowing users to explore transactions and contracts on this popular Ethereum sidechain.
- Arbiscan: The official block explorer for the Arbitrum network, an Optimistic Rollup scaling solution for Ethereum.
- Optimistic Ethereum Explorer: The official block explorer for the Optimism network, another major Optimistic Rollup layer for Ethereum.
- Ftmscan: The primary block explorer for the Fantom Opera chain, providing insights into transactions and smart contracts on this high-performance EVM-compatible platform.
- Cronos Explorer: The official block explorer for the Cronos chain, the EVM-compatible network built by Crypto.org.
Other Major Layer 1 Networks
Beyond Ethereum, several other Layer 1 blockchains have their own thriving ecosystems and dedicated explorers.
- Solscan: A powerful and user-friendly explorer for the Solana blockchain. It provides real-time data on transactions, blocks, tokens, and accounts on the high-speed network.
- TRONSCAN: The official block explorer for the TRON network, offering detailed analytics and data for all TRX-related transactions and smart contracts.
- Aptos Explorer: The official block explorer for the Aptos blockchain, a next-generation Layer 1 network designed for scalability and reliability.
- Avalanche Explorer: The official explorer for the Avalanche C-Chain, which is EVM-compatible and hosts the majority of dApps on Avalanche.
- Celo Explorer: The official block explorer for the Celo network, a mobile-first blockchain platform designed for financial inclusion.
Specialized and Niche Networks
Some explorers cater to specific technological niches or emerging ecosystems.
- zkSync Era Block Explorer (zkScan): The main explorer for the zkSync Era network, a zero-knowledge rollup scaling solution for Ethereum.
- Subscan: A premier explorer for the Polkadot and Kusama ecosystems, providing detailed data for parachains and their transactions.
- Filscan: A robust explorer for the Filecoin network, offering insights into data storage deals, mining activities, and FVM (Filecoin Virtual Machine) transactions.
- Metis Explorer: The block explorer for the Metis Andromeda network, an Ethereum Layer 2 scaling solution focusing on decentralized companies (DACs).
- NEAR Explorer: The official explorer for the NEAR Protocol, a developer-friendly sharded blockchain.
- Moonbeam & Moonriver Explorers: Official explorers for the Moonbeam (on Polkadot) and Moonriver (on Kusama) networks, which provide full EVM compatibility in the Polkadot ecosystem.
How to Choose the Right Blockchain Explorer
With so many options, your choice will primarily depend on the network you are using. For most users, the official explorer for a given chain is the best and most reliable option. They are typically the most up-to-date and offer features specifically designed for that ecosystem.
For developers, features like verified contract source code, read/write functionality, and API access are critical differentiators. For traders and investors, clean interfaces showing clear transaction histories and token information are most important.

Frequently Asked Questions
What is a blockchain explorer?
A blockchain explorer is an online tool that allows you to browse data on a blockchain. You can think of it as a search engine for a cryptocurrency network, where you can look up transactions, addresses, blocks, and other on-chain activity.
Is it safe to use a blockchain explorer?
Yes, using a block explorer is perfectly safe. You are only viewing publicly available data on the blockchain. You are not connecting your wallet or granting any permissions, so there is no risk of losing funds by simply looking up an address or transaction hash.
Do I need an account to use a block explorer?
No, the vast majority of blockchain explorers do not require you to create an account for basic viewing functions. Accounts are typically only needed for advanced developer features like API key management.
Why would my transaction be pending for a long time?
A transaction can remain pending if the network is congested or if you set a gas fee that is too low. Miners or validators prioritize transactions with higher fees. You can often check the explorer to see the current recommended gas price for a timely confirmation.
Can I see who owns a specific wallet address?
Blockchain explorers show the transaction history and balance of any public address. However, they do not automatically reveal the real-world identity of the owner. Addresses are pseudonymous; unless the owner has publicly linked their identity to an address, it remains anonymous.
What is the difference between a Layer 1 and a Layer 2 explorer?
A Layer 1 explorer (like Etherscan) shows data native to a base blockchain, such as Ethereum. A Layer 2 explorer (like Arbiscan) shows data from a secondary network that processes transactions off-chain before settling finality on the Layer 1. The data structure might look slightly different, but the core functionality is the same.
