I'm sitting here staring at my MetaMask extension, totally paralyzed. A client just paid me for a routine contract audit using an address that, according to Etherscan, interacted heavily with a sanctioned mixer back in late 2023. Now I'm sweating bullets. Seriously—am I carrying tainted funds?
I keep bouncing between confusing forum threads and massive legal blocks of text, trying to answer a deceptively simple question: Is Tornado Cash illegal?
Obviously, we all watched the Treasury Department drop the hammer. August 2022 was wild. The Office of Foreign Assets Control (OFAC) slapped the entire protocol on their SDN list. Bam. Done. But a smart contract is just immutable code sitting on Ethereum, right? You can't put math in handcuffs. Sure, the founders got dragged into court, but the protocol itself is still out there, completely decentralized and churning along.
I'm trying to map out my actual risk exposure here. I threw together a quick breakdown based on how compliance APIs normally treat these interactions. I really need you guys to fact-check my logic:
| Action | Assumed Legal Status (US Persons) |
| Publishing zero-knowledge privacy code | Protected speech (First Amendment) |
| Sending ETH directly to the TC router | Strict OFAC violation (Major trouble) |
| Receiving unsolicited ETH from a TC address | A terrifying gray area |
That last row is what keeps me up at night. If someone essentially forces downstreamed, anonymized Ether into my main hardware wallet (which I use for clean, everyday transactions), am I suddenly radioactive? My primary exchange requires pristine, crystal-clear provenance. If I attempt to cash out this specific audit payment, I'm terrified Coinbase will instantly freeze the whole stack.
Has anyone here actually dealt with getting their deposits locked because of accidental downstream exposure? How do you isolate this stuff without looking like you're actively trying to hide something? Talk to me.
