# Block Explorer ## Overview A block explorer is one of the most essential tools when building on Pharos. It gives you visibility into everything happening on-chain — from transactions and blocks to smart contracts and account activity. As a developer, you’ll frequently use a block explorer to verify deployments, debug issues, and track interactions with your contracts. ## What You Can Do with a Block Explorer * View transactions and check their status * Inspect blocks and network activity * Explore wallet addresses and balances * Interact with and inspect smart contracts * Verify deployed contracts and view source code ## Why It Matters The block explorer acts as your primary interface for understanding on-chain behavior. Whether you're testing on Testnet or deploying to Mainnet, it helps you quickly validate that everything is working as expected. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
