What is Blockchair?

Blockchair is a multi-blockchain search and analytics engine—think of it as “Google for blockchains.” It consolidates exploration tools for dozens of blockchain networks into a unified interface. With support for over 48 blockchains (including Bitcoin, Ethereum, Solana, Litecoin, and many more), it allows users to search, sort, and filter data for blocks, transactions, addresses, tokens, and metadata across multiple chains.
