+## Custom fuzzers
+
+We make extensive use of fuzzing when auditing software for bugs. To that end,
+we often build our own fuzzers when we cannot find one for the task at hand. The
+following is a list of fuzzers we have built and endorse using:
+
+- [Mishegos](https://github.com/trailofbits/mishegos): a differential fuzzer for x86 decoders
+- [Ruzzy](https://github.com/trailofbits/ruzzy): a coverage-guided fuzzer for pure Ruby code and Ruby C extensions
+- [Medusa](https://github.com/crytic/medusa): a parallelized, coverage-guided, mutational Solidity smart contract fuzzer
+- [Echidna](https://github.com/crytic/echidna): Ethereum smart contract fuzzer
+- [Tayt](https://github.com/crytic/tayt): StarkNet smart contract fuzzer
