Guido Vranken

I am number one in the Ethereum bug bounty program: https://ethereum.org/en/bug-bounty/

I have found hundreds of bugs in prominent cryptographic libraries. A subset of findings can be viewed here: https://gist.github.com/guidovranken/16a417eeabf6c0f5d8171fc2c1a80880

I privately maintain custom software to find bugs as well as very large fuzzing corpora (millions of tests for EVM's and cryptographic primitives).

I have previously worked for Ethereum, Aztec, Mayhem (previously ForAllSecure) and others.

Keywords: (differential) fuzzing, EVM's, cryptography and math.
