Overview
Blockchair is a versatile blockchain search engine and analytics hub that unifies data from a broad range of public blockchains. It aims to make blockchain information understandable and accessible for individuals, development teams, analysts, and researchers. The site combines visual explorers for each supported chain, token listings with market statistics, developer products such as an API and data dumps, and user-facing utilities like a browser extension and transaction receipts. A central theme is privacy-first design: Blockchair emphasizes minimal personal data collection and no sharing with third-party analytics or ad networks.
Core Capabilities
-
Unified Multi-chain Explorer: Search and inspect addresses, transactions, blocks, and tokens across dozens of blockchains from a single interface. This saves time compared to switching between many separate explorers.
-
Developer API with SQL-like Queries: Access on-chain data programmatically via a REST API that supports powerful filtering and sorting. The API is designed for integration into apps, research pipelines, and analytics dashboards.
-
Token Directory and Market Data: Browse tokens with market caps, circulating supply, price, and percent changes. Token pages aggregate contract and supply information across supported chains.
-
Data Exports and Datasets: Download raw blockchain dumps and structured datasets for offline analysis, academic research, or building bespoke analytics solutions.
-
User Tools and Utilities: Generate transaction receipts and wallet statements, use a browser extension for quick lookups, and broadcast raw transactions through provided tools.
Products & Services
Blockchair offers multiple product entries oriented at different user needs. These include:
- Explorers for individual chains with up-to-date block/slot and fee information.
- Tokens pages that provide market metrics and direct links to token pages across chains.
- API access for developers who need programmatic retrieval of blockchain data.
- Datasets/Dumps for researchers and teams that require bulk on-chain data.
- Browser Extension and Chat Assistant for convenient, interactive queries and conversational help.
Each product is linked from the main site and designed to support both casual lookups and production integrations.
API & Data Access
Blockchair’s API advertises a single entry point for multiple blockchains with features tailored to developer workflows. The API supports structured queries reminiscent of SQL, allowing for sorting, filtering, and paginated responses. This makes it suitable for applications like analytics dashboards, academic studies, market monitoring tools, and automated data ingestion processes. For teams that need offline or custom analysis, downloadable data dumps and curated datasets are available, enabling reproducible research and custom pipeline construction.
Privacy & Security
Blockchair positions itself as a privacy-conscious blockchain search engine. The platform states it does not collect personal data or share users’ information with third-party analytics or ad networks. This approach reduces the risk of linking search activity to identifiable users and helps preserve the confidentiality of balances and addresses when people interact with the service. Additionally, standard security practices apply for API keys and integrations to protect access to higher-volume or private endpoints.
