Fuzzing Techniques
Fuzzing is an automated software testing technique that involves injecting massive amounts of random or semi-random data into a smart contract to trigger unexpected behavior or crashes. By pushing the system to its limits, fuzzing can uncover edge cases that manual testing and unit tests often miss.
In the context of DeFi, fuzzing is used to find vulnerabilities related to integer overflows, invalid state transitions, and logic errors. It is a highly effective way to increase the robustness of financial protocols against adversarial inputs.
Advanced fuzzers can learn from previous runs to target more complex areas of the code. It is a staple of modern security engineering.

Formal Verification
Algorithm ⎊ Formal verification, within cryptocurrency and financial derivatives, represents a rigorous methodology employing mathematical proofs to ascertain the correctness of code and system designs.
Smart Contract
Function ⎊ A smart contract is a self-executing agreement where the terms between parties are directly written into lines of code, stored and run on a blockchain.
