Meaning
Detailed step-by-step log of every internal call and state change triggered by a single interaction with a smart contract. A transaction trace allows a founder to see exactly how a complex function executed, including any interactions with other contracts or error messages that were not visible in the basic transaction record. It provides the granular evidence needed to debug a failure or audit a suspicious event.
This record provides a thorough account of a system’s behavior during a specific moment in time.
Diagnostic Utility
When a transaction fails, the trace reveals the specific line of code where the error occurred, allowing for a rapid recovery. This information is indispensable for developers who must maintain the system after the initial launch and ensure its continued operation. It captures the flow of value through several layers of the application.
The storage of these traces requires substantial capacity compared to standard block headers.
Audit Trail
Security professionals use these logs to ensure that no unauthorized logic was executed during a routine call. The trace proves that the system behaved exactly as expected under the given inputs. It is the primary tool for verifying the correctness of a financial claim.
Data Granularity
Detail is provided at the level of individual assembly instructions if required.
