Best blockchain explorers compared
A blockchain explorer is a website that lets you look up what happened on a blockchain: a transaction, an address, a token or a block. There is no single best one. Each is built around one chain or one job, so the right choice depends on what you want to look at. This page compares the common free ones and says what each is good for.
Quick picks
| You want to look at | Start with |
|---|---|
| Ethereum | Etherscan |
| BNB Chain, Polygon, Arbitrum and other EVM chains with their own explorer | The matching Etherscan-family site (BscScan, Polygonscan, Arbiscan) |
| A newer or smaller EVM chain | Blockscout |
| Bitcoin and many other coins in one place | Blockchair |
| Bitcoin transactions that are still unconfirmed | mempool.space |
| Solana | Solscan |
| Tron | Tronscan |
| Several chains with labels and analytics | OKLink |
| Who an address has dealt with, as a picture | An investigation tool (see below) |
The explorers
Etherscan (and its sister sites)
The reference explorer for Ethereum. It shows transactions, token transfers, internal transactions, contract code and a token approval checker, and many addresses carry a name label. The same team runs sister explorers for other EVM chains, such as BscScan for BNB Chain, Polygonscan and Arbiscan, with the same layout.
- Good for: depth on Ethereum and the chains with their own sister site.
- Limits: one site per chain, a dense interface for beginners, and labels are far from complete. See also: Reading Etherscan for beginners.
Blockscout
An open-source explorer that many networks run for themselves, including a lot of newer and layer-2 chains. Each network has its own instance, and the interface is similar everywhere.
- Good for: chains that have no big explorer of their own, and anyone who wants to host an explorer.
- Limits: quality and speed depend on the instance for each chain.
Blockchair
A multi-chain explorer that covers Bitcoin, Ethereum and a long list of other coins, with one search box for all of them.
- Good for: Bitcoin and coins that are not EVM, and quick cross-chain lookups.
- Limits: less detail on smart-contract activity than a dedicated EVM explorer.
mempool.space
An open-source Bitcoin explorer with a live view of unconfirmed transactions and fee levels.
- Good for: Bitcoin only, especially "why is my transaction still pending".
- Limits: Bitcoin only.
Solscan and Tronscan
The usual explorers for Solana and Tron. Both are built for the specifics of their chain (Solana accounts and signatures, Tron's resource model and TRC-20 tokens).
- Good for: their own chain, with token and account detail that general explorers skip.
- Limits: one chain each. See also: How to track a Tron or Solana wallet.
OKLink
A multi-chain explorer with address labels and analytics across many networks.
- Good for: one place for several chains, with labels.
- Limits: the depth varies by chain.
3xpl
A multi-chain explorer that is known for a fast, ad-free interface.
- Good for: quick lookups across chains.
- Limits: a lighter feature set than the chain-specific explorers.
Explorer or investigation tool?
An explorer answers "what happened in this transaction or at this address". It does not make it easy to answer "who has this wallet dealt with, and is any of it suspicious". Investigation tools build a picture from the same on-chain data, usually as a connection graph with labels:
- MetaSleuth and Breadcrumbs focus on fund-flow visualisation for investigations; some depth sits behind an account or a paid plan.
- Arkham maps entities and labels across chains.
- Hopchain (the author's tool) is free and needs no signup: paste an address and see the wallets and contracts it has dealt with, with known-entity labels, flags for known scam and sanctioned addresses, and a pairwise or bulk Sybil check. Its limits: label coverage is much smaller than the big platforms, it does not cover Bitcoin, and a clean result never proves an address is safe. See how Hopchain compares with MetaSleuth.
How to choose
- Which chain? Start with that chain's own explorer.
- A single transaction? Use the explorer for its chain and the transaction hash. See How to check a TXID.
- A wallet's history and connections? An explorer for the list, an investigation tool for the picture.
- A pending Bitcoin payment? mempool.space.
Whatever you use, compare the result with a second source before acting on it, especially if money is involved.

Frequently asked questions
What is a blockchain explorer?
A website that reads a blockchain and shows its transactions, addresses, tokens and blocks in a
searchable form. It only displays public data and cannot move funds.
Do I need an account?
Not to look things up. Most explorers work without signing in. Accounts are mostly for API keys,
watchlists or alerts.
Is there one explorer for every chain?
No. Some cover many chains, but each chain's own explorer usually has the most detail.
Can a block explorer tell me who owns an address?
No. It shows activity and sometimes a label for well-known entities. The owner of most
addresses is not public.
Which explorer is best for beginners?
The explorer of the chain you use, with the transaction hash from your wallet or exchange. The
dedicated ones explain the fields best.
