Introduction

Ethereum Virtual Machine (EVM) transaction tracing is a powerful feature for debugging and understanding the behavior of smart contracts. Tracing allows you to follow the execution path of a transaction, providing insights into each step of the process, including function calls, state changes, and gas usage.

Why Trace Transactions?

Tracing transactions can be beneficial for:

• Debugging complex smart contracts.
• Analyzing gas consumption.
• Auditing and verifying contract behavior.
• Understanding transaction failures or unexpected outcomes.

To get all of the transaction details, you need to replay the transaction in the Ethereum Virtual Machine and collect the execution data during the process. This is called transaction tracing.
