This grant will fund a full penetration test of the dYdX frontend and indexer codebases, neither of which were formally audited as part of the dYdX v4 launch. Halborn will run a deep dive on both codebases in an effort to find and disclose any vulnerabilities with these critical pieces of dYdX infrastructure. A report will be shared with the DEP, the DOS, and the dYdX Trading team with recommendations on how to patch any vulnerabilities identified through this exercise.
