Key Takeaways

  • No mixer is untouchable. Even ChipMixer, which processed ~$3 billion, was eventually seized through coordinated international law enforcement (BKA, Europol, FBI).
  • OFAC sanctions change the game. Blender.io and Tornado Cash were sanctioned under US executive order, making any interaction illegal for US persons regardless of intent.
  • Operator arrests are the primary vector. Most mixer takedowns stem from identifying and arresting the operator, not from breaking the mixing protocol itself.
  • Decentralization matters. Tornado Cash's smart contracts continue to function despite sanctions and developer arrests, demonstrating the resilience of truly non-custodial, on-chain protocols.
