# Understanding transaction hashes A transaction hash, also known as a transaction ID, is a **unique string of characters** that is assigned to every transaction that occurs on the blockchain. This hash can be used to track and verify the status of a particular transaction. To view the details of a transaction, users can use a tool called a block explorer, such as [etherscan.io](https://etherscan.io/) or [bscscan.com](https://bscscan.com/). These tools allow users to enter the transaction hash and view information about the transaction, including the amount, the sender and recipient addresses, and the status of the transaction. --- # 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.
