Hi! It looks like your question is outdated already, however, if somebody would find yourself in the same situation, I can advise some solutions. Considering the fact that most of the community represent small groups of blockchain enthusiasts and individual researchers, I wouldn’t recommend such sophisticated solutions like Chainalysis or Ciphertrace due to their corporate-shaped forms and pricing. I personally use the tool, made by the Cryptohound team (c-hound.ai), which is more advanced than an average wallet explorer, yet free and accessible (unlike professional B2B crypto forensics tools).
