Blockscan: 25+ Blockchain Explorers

Network & Web, Search

Free
No Download/Install required
No registration

Inspect and explore more than 25 different blockchains to view users, portfolios and transactions: Blockscan functions as a comprehensive search engine and data aggregator for Ethereum Virtual Machine (EVM) compatible blockchains.

It provides a unified interface to query addresses, transaction hashes, and smart contracts across multiple networks, including Ethereum, BNB Chain, and various Layer 2 solutions. The service integrates Blockscan Chat, a decentralized messaging protocol that allows for encrypted, wallet-to-wallet communication.

These capabilities allow technical leads to verify operational compliance and mitigate risks associated:

Validate the provenance of critical components by auditing immutable ledger entries across disparate production networks.
Monitor the execution of smart contracts governing automated quality control systems and multi-party service level agreements.
Track the lifecycle of digital twins and intellectual property assets in decentralized science frameworks to ensure data integrity and funding transparency.

Disciplines: Cryptocurrency, Blockchain, Finance, Cybersecurity, Accounting.

Free alternative to Etherscan, Blockchair, Dune.

Blockscan compared with Etherscan, Blockchair and Dune
Blockscan	Etherscan	Blockchair	Dune
Chain coverage: Blockscan presents itself as a multichain explorer and states that it supports 30+ chains. One interface replaces opening a separate explorer for each network.	Chain coverage: Etherscan itself covers Ethereum Mainnet plus the Sepolia and Hoodi testnets. Its API V2 reaches 50+ blockchains with a single key.	Chain coverage: Blockchair lists Bitcoin, Ethereum, Ripple, Litecoin, Bitcoin Cash, Cardano, Stellar, Monero, Tezos, Dash, Zcash and Dogecoin among others.	Chain coverage: Dune states that it indexes 100+ blockchains and holds more than 3 petabytes of data. Coverage is much wider than a lookup explorer, but it is reached through queries.
Type of analysis: Blockscan offers portfolio views with grouped addresses, a cross-chain transactions section, multichain charts and alerts. It is built for looking up single addresses and transactions.	Type of analysis: Etherscan provides transaction and block search, smart contract verification, address labels, token approval checks, a gas tracker and CSV export for one chain.	Type of analysis: Blockchair supports search for transactions, addresses, blocks and embedded text data. Users can also filter, sort and extract custom datasets.	Type of analysis: Dune is an analytics platform with a web-based SQL editor, dashboards and scheduled queries. You write the question yourself instead of reading a fixed explorer page.
Programmatic access: The Blockscan page does not describe an API. It links a VSCode IDE, a mobile app and an Explorer as a Service offer, without further detail.	Programmatic access: Etherscan sells an explorer API. The free tier is listed at 3 calls per second and 100,000 calls per day for selected chains, for personal and research use.	Programmatic access: The Blockchair API lists 18 blockchains. The free plan has a hard limit of 30 requests per minute, and database dumps are not part of API plans.	Programmatic access: Dune offers a Data API to execute queries and fetch results. A Trino connector links BI tools such as Metabase, DBeaver and Power BI to its data.
Licence and cost model: The Blockscan site shows no pricing or plans. It is operated by the team behind Etherscan.	Licence and cost model: Etherscan lists paid API plans, starting with the Lite plan. Commercial use requires the Advanced plan or higher.	Licence and cost model: Blockchair sells API access in blocks of calls per plan. The page gives no prices.	Licence and cost model: Dune free accounts are view-only and cannot run queries. A 14-day trial includes 2,500 credits, and paid tiers are Analyst, Plus and Enterprise, billed through credits based on compute used.
