A comprehensive blockchain query toolkit | Full coverage from on-chain monitoring to market analysis

Entering the world of crypto for investment, development, or research, the biggest concern isn’t market volatility but the inability to find reliable data. The importance of blockchain query tools lies here—they enable you to quickly access on-chain data, monitor project trends, and analyze market movements. This article compiles the most commonly used blockchain query platforms and tool libraries in the industry to help you quickly identify the data sources you need.

On-Chain Data Queries: The First Step to Understanding Blockchain

To understand the true operation of a public chain, you must start with on-chain data. These tools focus on extracting the most core information from blockchains.

Glassnode is a professional on-chain data provider, offering in-depth metrics such as coin holder distribution, exchange balances, and miner transfers. While advanced features require a paid membership, weekly free on-chain analysis reports are still worth paying attention to.

CoinMetrics.io excels in cross-asset comparisons—you can compare major cryptocurrencies like Bitcoin and Ethereum, and even perform correlation analysis with traditional financial assets. It’s an essential website for blockchain data queries.

If you want to get started quickly without paying, Tokenview offers free charts and data visualization covering public chains, NFTs, DeFi, and stablecoins across multiple fields. OKLink supports cross-chain queries, allowing you to view data related to public chains, DeFi, GameFi, NFT, and other hot projects in one stop.

Blockchair aggregates browser functions for multiple mainstream public chains, saving you the trouble of querying each one separately.

Market and Trading Data: Quickly Access Market Dynamics

Traders and investors are most concerned with real-time market prices and technical analysis. These tools help you stay in tune with market movements.
