Etherscan alternatives that actually hold up

General-purpose Etherscan alternatives

Blockscout: the self-hostable all-rounder

If you want one replacement that covers nearly everything Etherscan does, it is Blockscout. The Ethereum instance at eth.blockscout.com shows transactions, internal calls, token transfers, NFTs, verified contracts with Read/Write tabs, and it was quick to support blobs and EIP-7702 delegations. The code is public (GPL-3.0 until v10.2.0, a source-available licence since v11 in April 2026) and runs on more than a hundred chains, so the interface you learn here works on Gnosis, many rollups and plenty of private networks. The API is the big draw: its REST v2 and Etherscan-compatible endpoints answer without a key, and a free developer key adds 100,000 credits a day at 5 requests per second across 120+ chains. Labels for exchanges and protocols are thinner than Etherscan’s. Full details are in our Blockscout review.

Blockchair: privacy and one search box for 40+ chains

Blockchair treats Ethereum as one chain among forty-odd, which is exactly why multi-chain researchers like it. Its filters let you sort transactions by fee, value or time the way you would in a spreadsheet, and its privacy stance is the strongest among the big hosted explorers. During our check its stats endpoint counted about 3.75 billion Ethereum transactions and 1.83 million in the previous 24 hours. Contract tooling is thin, and the keyless API allows around 1,440 requests a day with a hard cap of 30 a minute. Our Blockchair review goes deeper.

Routescan: the Etherscan-compatible transaction explorer

Routescan started in the Avalanche world and now runs explorers for a long list of EVM chains. As an Ethereum transaction explorer it is plain but correct. The real reason to know it is the API, which mirrors Etherscan’s module and action parameters, so existing code often needs only a new base URL. We called api.routescan.io/v2/network/mainnet/evm/1/etherscan/api for the latest block and for the balance of vitalik.eth’s address with no key at all and got clean JSON back, with CORS open for browser apps. Routescan has advertised a free tier of 5 requests per second and 100,000 a day; paid plans lift that. It is also listed among developer tools on ethereum.org.

Blockchain.com explorer: an Ethereum dashboard, not a workbench

Many people know Blockchain.com from Bitcoin, and its Ethereum page works in a similar way. The top half is a price chart; underneath you get a live strip of recent block numbers, market cap, supply and 24-hour volume, and a search box that accepts Ethereum addresses and transaction hashes. For a glance at “is my ETH there?” it is fine. For anything more, it is not: there are no verified contracts, no decoded input and no traces. One detail made us wince. When we visited, the “about” panel still listed the algorithm as Ethash and said Ethereum uses proof of work, four years after the Merge. Treat the Blockchain.com Ethereum explorer as a dashboard with a search box.

OKLink: labels and risk scores

OKLink, run by the OKX group, is a large multi-chain explorer with a strong compliance flavour. Its address pages carry risk labels, and it offers private labels, address monitoring and a token approval checker, similar to Etherscan’s. The same data also appears inside the OKX Wallet explorer. The interface is busy and the API needs a key, but if you want a second opinion on whether an address is tied to a hack or a sanctioned entity, it is worth a look.

Tokenview: still alive, harder to reach

Tokenview, a multi-chain explorer founded in 2016, is still online in 2026 and claims coverage of over a hundred chains. It covers the Ethereum basics: blocks, addresses, transactions and token balances. What changed is access. The site now routes visitors through a browser challenge page before loading anything, which slows quick lookups and makes scraping pointless, so its paid API is the practical route. We would keep it as a backup rather than a daily driver.

Developer and security alternatives

Tenderly: why did it revert?

Etherscan tells you a transaction failed. Tenderly’s Developer Explorer tells you why. Open a failed swap and you see the full call trace with the exact internal call that reverted, decoded events, state changes per storage slot, a step-through debugger and a gas profiler drawn as a flame chart. The simulator lets you replay the same transaction with a higher gas limit or different parameters before you spend real ETH again. You need an account, the free plan limits you to around 20 monitored contracts or wallets, and there is no API access on free. For anyone who writes or audits Solidity, it is the first tab we open after a revert. Our smart contract explorer guide explains the underlying concepts.

Phalcon by BlockSec: follow the stolen money

Phalcon is built by the BlockSec security team, and it shows. A single transaction page shows the invocation flow, a fund-flow graph of every token movement, balance changes for every address involved and the storage variables that changed, which traces alone often miss. Because it supports well over twenty chains, researchers use it to trace attacks that hop between networks. It is not the tool for checking a deposit, but when a protocol you use makes headlines for the wrong reasons, Phalcon is where you will understand what happened.

Otterscan: your own explorer, on your own node

Otterscan is the privacy answer. It is an MIT-licensed web app that talks to your own Erigon archive node through the ots_ RPC namespace, so nobody else sees what you look up. Pages load fast, internal transactions are shown as a proper tree, and there are no ads or accounts. Support for Reth and Anvil exists but is partial, so Erigon remains the smooth path. The price is a synced archive node, which is a real commitment of disk space. Our open-source Ethereum explorer guide walks through the setup.

Those three steps cover most migrations we have seen. For the exact rate limits per provider and example requests, read our guide to Ethereum block explorer APIs.

The Trezor Ethereum explorer and what happened to Bloxy

Trezor’s explorer at eth1.trezor.io

Hardware-wallet owners sometimes land on eth1.trezor.io from a link in Trezor Suite. It is a Blockbook instance, the open-source indexer (AGPL-3.0) that SatoshiLabs built to serve balances and history to its wallet software. The status page is refreshingly honest: when we checked it was running Blockbook 0.6.0 on an Erigon 3.5.5 archive node with Prysm as the consensus client, fully synced at block 26,046,161. You can open an address, see its ETH and token balances, browse transactions, and even broadcast a signed raw transaction. Just take the footer seriously: the service is provided for Trezor Suite and says not to use it for anything else, so it is no base for an app. If you like the approach, Blockbook is on GitHub and can be self-hosted.

bloxy.info: gone, but not forgotten

Bloxy was the explorer people used to trace money flows between contracts long before fund-flow graphs were common. In September 2026, bloxy.info no longer serves its own pages. It answers with a permanent redirect to explorer.bitquery.io. That is not a takeover; Bitquery is the company that grew out of Bloxy, and its explorer is built from widgets on top of the Bitquery GraphQL API. Heavy users should know that Bitquery deprecated its older V1 API for Ethereum in favour of V2, so old saved queries may need rewriting. If you want Bloxy-style money-flow views without writing GraphQL, Phalcon’s fund-flow tab is the closest modern equivalent.

Choosing the right Etherscan alternative

If you only change one thing, add Blockscout as your second explorer. It handles almost every lookup and gives you a free, keyless API. Keep Routescan in reserve for Etherscan-style calls. Reach for Tenderly or Phalcon when a transaction behaves oddly, and for Otterscan when privacy matters more than convenience. For staking data you need a different class of tool, covered in our beacon chain explorer guide, and for rollups see the layer 2 explorer overview.

Whatever you pick, the habit that protects you most is the same: after any deposit, withdrawal or swap, paste the hash into a second explorer and confirm it independently. It takes ten seconds, and our transaction explorer guide shows what to look for.
