Source Code Mapping

Source code mapping is the technical process of linking specific sections of high-level source code to their corresponding addresses or instruction sets within the compiled bytecode. This mapping is essential for debugging and security analysis, as it allows developers to pinpoint exactly where a logical error or vulnerability exists within the complex bytecode structure.

By creating a map, auditors can trace the execution flow of a contract and observe how it handles inputs and outputs. This transparency is particularly important in DeFi, where complex financial logic must be executed correctly every time.

Without effective source code mapping, identifying the root cause of a failure or an exploit becomes significantly more difficult and time-consuming. It is a fundamental component of professional smart contract development and auditing workflows.
