Path Exploration
Path exploration is the systematic process of traversing all possible execution branches within a smart contract to identify potential vulnerabilities or unexpected behaviors. Because smart contracts often contain complex conditional logic, the number of possible paths can be enormous.
Symbolic execution uses path exploration to represent each branch as a mathematical constraint, allowing the analyzer to evaluate the entire logic tree of the contract. By exploring every path, the system ensures that no hidden edge cases are left unexamined.
This is crucial for derivatives where specific market conditions might trigger rarely used code paths. Path exploration transforms the qualitative complexity of code into a quantitative search problem.
It is the mechanism by which formal tools provide comprehensive security coverage.
