Block explorer
A block explorer is a public interface for looking up blockchain blocks, transactions, addresses, contracts, and tokens.
Quick answer
What is a block explorer used for?
A block explorer is a lookup interface for public chain data such as blocks, transactions, addresses, contracts, and tokens. On Main.net, explorer links are paired with the chain ID, RPC URL, gas token, and source documentation so users can verify the full network context instead of trusting a hostname by itself.
Why it matters
This term matters because wallet setup, RPC configuration, and chain selection can affect where transactions are signed and submitted. A familiar label is not enough: users and developers should verify exact network values against source documentation before moving funds or deploying production systems.
On Main.net, glossary pages connect to status pages, guides, gas-token pages, explorer pages, and JSON feeds. Use the definition to understand the concept, then follow the related guide when you need the operational checklist or the current chain fields.
Block explorer verification checklist
- Confirm the chain name and chain ID on the status page.
- Compare the explorer hostname with linked source documentation.
- Use the explorer for lookup, not as proof that a token, contract, bridge, or address is safe.
- Keep RPC URLs, explorer URLs, and wallet config fields separate when debugging a setup issue.
Common verification habit
Before copying a setting from any reference site, compare the term in context with the official project documentation: chain ID with chain ID, RPC URL with RPC URL, gas token with gas token, and explorer host with explorer host. If one value is stale or inconsistent, stop and use the source documentation as the deciding reference.
