Abstract Syntax Tree

An abstract syntax tree is a tree representation of the abstract syntactic structure of source code written in a programming language. Each node of the tree denotes a construct occurring in the source code, such as a variable declaration, an expression, or a control flow statement.

Static analysis tools use these trees to understand the semantic meaning of the code, allowing them to identify patterns that represent potential security vulnerabilities. By traversing the tree, tools can perform deep analysis of how data is used and transformed across the contract.

It is a fundamental data structure in compiler design and static analysis frameworks. Mastering this structure allows for the development of custom security checks tailored to specific protocol needs.
