Samourai Wallet Is Dead. Is Your Wallet Still Flagged?

Samourai Wallet's founders are now in federal prison, but wallets that used its Whirlpool or Ricochet mixing tools still carry the same screening exposure Tornado Cash addresses do.

Prison time for two developers doesn't erase five years of on-chain history. Every UTXO that ran through a Whirlpool CoinJoin round is still sitting in the same clustering graph analytics firms have mapped since 2019. The sentencing didn't soften anyone's stance on it, either. Compliance teams now cite a federal money-transmitting conviction as the reason to keep flagging mixer-touched deposits, not a reason to relax.

What Happened to Samourai Wallet's Founders?

Keonne Rodriguez and William Lonergan Hill built and ran Samourai Wallet, a non-custodial Bitcoin wallet with built-in mixing features, from around 2015 until federal agents seized its servers in April 2024. Rodriguez was sentenced to five years in prison on November 6, 2025. Hill followed on November 19, 2025, with four years. Both pleaded guilty to conspiracy to operate an unlicensed money-transmitting business, according to IRS Criminal Investigation, which put the total laundered through the platform at more than $237 million across over $2 billion in processed transactions.

Both men forfeited over $6.3 million in fees and were fined $250,000 each, with three years of supervised release to follow. The case was built around drug proceeds, darknet market payouts, and funds tied to sanctioned jurisdictions moving through the app's Whirlpool and Ricochet features. The case is closed. The graph isn't.

What Did Samourai Wallet Actually Do?

Whirlpool ran CoinJoin rounds. Groups of users pooled their bitcoin into one transaction with equal-sized outputs, breaking the direct input-to-output link a chain analyst would otherwise trace. Ricochet added a few extra hops after a Whirlpool round, routing coins through addresses the sender didn't control before they reached their final destination. Neither feature moved coins off-chain. They rearranged the graph.

That distinction matters now. A CoinJoin transaction is still fully visible on the Bitcoin ledger, and nothing about the sentencing changed what's on it. What changed is how confidently a compliance officer can point at a mixer-touched wallet and call the exposure deliberate.

Does a Whirlpool-Mixed Wallet Get Flagged Today?

Yes. Exchange risk engines don't check whether a service is still running or whether its founders went to prison. They check whether an address's funds passed through clusters tagged as a mixer, and Samourai's clusters were tagged years before the arrests. Plastron's own dataset carries 28 addresses classified specifically as mixer infrastructure inside a broader set of 3,901 labeled entities, and mixer exposure sits near the top of the risk weighting alongside sanctioned addresses and stolen-fund clusters. The exposure doesn't expire.

A manual look at a block explorer like mempool.space will show you the raw CoinJoin transaction. It won't tell you how many hops separate your current balance from a tagged cluster, or how an exchange's risk model will score that distance. Screen the wallet with Plastron and you get the hop count, the OFAC and mixer exposure, and the full picture across seven chains in one pass.

Some of those mixer-tagged clusters have sat in screening datasets since before the 2024 server seizure. Age doesn't remove the tag. It just means the cluster has had longer to accumulate downstream addresses that inherit the same flag.

Is Samourai Exposure Scored Differently From Tornado Cash?

Mechanically, yes. Tornado Cash is a set of Ethereum smart contracts, so exposure gets flagged through contract-interaction tags. Samourai is Bitcoin, so the same job runs on the co-spend and change-address heuristics chain analysts have used since 2013 (the Tornado Cash side of this same problem works through the Ethereum version of it). Both end at the same place: a risk score that climbs with proximity to the mixer cluster and doesn't come back down on its own.

One hop from a Whirlpool round reads differently than five hops. Most risk engines decay the score with distance. Decay isn't zero. A wallet that touched Ricochet in 2021 and has moved a dozen times since still carries the mixer in its ancestry.

What Should You Do If Your Wallet Touched Samourai's Tools?

Check exposure before you deposit, not after support puts your withdrawal on hold. If a scan shows mixer-cluster proximity, expect an exchange to ask where the funds originated and how long ago the mixing happened. Have that answer ready before they ask it. Check first. Then deposit.

Document the transaction history yourself. A timestamped record of when the coins moved through Whirlpool or Ricochet, and what happened to them afterward, is the difference between a same-day review and a multi-week hold.

A short source-of-funds note helps more than a long one. State the date of the mixing round, the wallet's history since, and why the funds are legitimate now. Attach the scan report. Compliance analysts read dozens of these a week, and a wallet that shows its own exposure before being asked moves through review faster than one that waits to be caught.

FAQ

Is using Samourai Wallet illegal?

No. Using a non-custodial wallet with mixing features has never been illegal for the end user. The founders were convicted for operating an unlicensed money-transmitting business, not for the act of mixing coins itself.

Can old Samourai Wallet transactions still be traced?

Yes. CoinJoin breaks the obvious input-to-output link, but the transaction itself stays on the Bitcoin blockchain forever. Clustering heuristics developed since 2013 can still map the participants in many rounds.

Does OFAC sanction Samourai Wallet the way it sanctioned Tornado Cash?

No. Treasury's OFAC sanctioned Tornado Cash's smart contract addresses directly in 2022. Samourai's case ran through the Department of Justice as a criminal money-transmitting prosecution, not a Treasury sanctions designation.

How do I check if my wallet has mixer exposure?

Run the address through a screening tool that checks known mixer clusters, not just a sanctions list. Plastron's free scan flags mixer proximity, OFAC status, and stolen-fund links across Ethereum and six other EVM chains in one report.
