## Dynamic Security Testing

Dynamic testing, or fuzzing, involves providing random, unexpected, or invalid data inputs to a smart contract to observe its behavior during execution. By running the contract in a controlled environment, developers can uncover edge cases that static analysis might miss.

This method is highly effective at finding unexpected state transitions or crashes that could be exploited by malicious actors. It simulates real-world usage under extreme conditions, helping to ensure the robustness of the protocol.

It is a critical component of modern security practices, often used alongside formal verification to provide comprehensive coverage.
