# Reading the Chain 

### Overview / why it matters

Block explorers show what actually happened. Use them to verify deposits, claims, and contract details.

### Core concepts

* Explorer: Website to view blocks, accounts, and contracts.
* Tx hash: Unique ID of your transaction.
* Contract address: Where a token or app lives on-chain.
* Verified contract: Source code published and matched.
* Events/logs: Data emitted by contracts (e.g., “Transfer”).

### Key takeaways

* Always match the token contract before buying or claiming.
* A “success” on the explorer confirms the transaction’s outcome.
* Copy your tx hash to track status or share with support.
