Block Explorers are one of the most important tools for any Data Analyst/Scientist. In a nutshell, they allow you to well... explore a blockchain!
More specifically, Blockchain Explorers provide an online interface for you to look up any particular blockchain of choice, and retrieve data about transactions, addresses, blocks, and fees, amongst others.
Here, you'll find the primary web-based explorers for the most popular blockchains.
While they won't let you do half of the cool things Dune does, they're indispensible for figuring out how certain protocols work and what data you need to include in your queries:
- Ethereum - Etherscan
- Solana - Solscan
- Arbitrum - Arbiscan
- Polygon - Polygonscan
- Optimism - Optimistic.Etherscan
- Avalanche C-Chain - Snowtrace
- Binance Smart Chain - BscScan
- Gnosis Chain - Gnosisscan
