FinCEN Withdraws Unhosted Wallet and Crypto Mixer Rules: What Changes for Crypto Privacy in the US

What exactly FinCEN withdrew

On October 5, 2026, FinCEN, the US Treasury bureau that fights financial crime, filed two notices for public inspection withdrawing proposed rules. Formal publication in the Federal Register is set for October 6. Neither proposal ever took effect, yet for years both sat on the books and shaped the whole debate about privacy in American crypto.

The 2020 unhosted wallet rule

The first proposal was published on December 23, 2020, in the final weeks of the previous administration. It targeted so-called unhosted wallets, meaning self-custody wallets where the owner holds the keys instead of an exchange. Banks and money services businesses, crypto exchanges included, would have had to:

• keep records and verify customer identity for transfers to and from such wallets above $3,000;
• file a report with FinCEN for transfers above $10,000, including counterparty details such as the wallet owner's name and address;
• aggregate smaller transfers over 24 hours and report them if together they exceeded $10,000.

In plain terms, withdrawing bitcoin from an exchange to your own wallet would have become something the exchange reports to the government. FinCEN's notice is short: it will take no further action on this proposal.

The 2023 crypto mixing rule

The second proposal, from October 2023, dealt with mixing. FinCEN wanted to designate international crypto mixing as a class of transactions of primary money laundering concern under Section 311 of the PATRIOT Act. Financial institutions would have had to report wallet addresses, transaction hashes and IP addresses tied to mixers.

The problem was the definition. Mixing covered pooling funds, splitting transfers, single-use wallets, coin swaps and delayed transactions. An ordinary user who opens a fresh address for every payment, or swaps one coin for another on a crypto exchange to get it straight into their own wallet, fits that description easily.

Why the regulator backed off

FinCEN says the decision was largely driven by public comments: commenters warned that the broad definition could chill legitimate activity and pile a heavy reporting burden on banks and exchanges. The agency also points to the July 2025 report of the President's Working Group on Digital Asset Markets, which says the administration supports the ability of lawful users to transact privately on public blockchains. Washington now describes its approach as fit-for-purpose regulation: rules aimed at specific risks rather than blanket surveillance.

Coin Center, a nonprofit crypto policy group, called the withdrawal a major victory for financial privacy. Its executive director, Peter Van Valkenburgh, also cautioned that the legal authority to issue similar bad rules is still there. FinCEN itself noted that it will keep monitoring illicit activity and reserves the right to act further.

What stays in place

Only two proposals were withdrawn, and oversight remains. Crypto exchanges and money services businesses in the US still operate under:

• the Bank Secrecy Act (BSA) and anti-money laundering programs;
• identity checks (KYC) when you open an exchange account;
• suspicious activity reports;
• OFAC sanctions, which prohibit transfers to sanctioned addresses;
• the Travel Rule for transfers between services, where sender and recipient data travel with the transfer.

So your exchange still sees where you withdraw and can ask about a large or unusual withdrawal. Self-custody is no longer a trigger for separate reporting, but it does not make you invisible either. If you keep coins on an exchange out of habit, it helps to understand the difference between a custodial and non-custodial wallet and who actually controls your money.

The US and Brazil: opposite directions

In the same month, another large crypto market went the other way. Since October 1, crypto services in Brazil report transfers of $10,000 or more to and from self-custody wallets to the financial intelligence unit, in almost the same shape FinCEN just abandoned. We covered the details in our piece on Brazil's new reporting rule for self-custody wallet transfers.

The takeaway is simple: privacy rules are set country by country, and US news does not cancel local requirements. Check the rules where you live and where your exchange is registered.

What this means if you hold your own coins

For US users, the signal matters most. Self-custody and private transactions are officially no longer a suspicious class of activity. Your own wallet, a fresh address for every deposit, and privacy coins like Monero or Zcash remain lawful tools as long as the money is clean and the taxes are paid.

Not all on-chain privacy is equal, though. Bitcoin is transparent: anyone can see amounts and links between addresses. Monero hides the sender, receiver and amount by default, which is why people pick it when they do not want their payment history on public display. Restrictions on such coins come from some exchanges' own policies, not from US law.

Where to swap BTC to Monero without an account

The easiest setup is to keep privacy coins in your own wallet and swap them without extra middlemen. That is exactly how VertEXchange works: there is no account, and we never ask for a login, email or phone number. You enter your own wallet address and the coins arrive straight to it. The rate and the final amount are shown in the form before you send anything, and a fixed rate is held for about 15 minutes, so you have time to send your coins calmly. Once your funds arrive, the swap is processed automatically. If you want to swap BTC to XMR without registration, open the pair, paste your Monero wallet address and send your bitcoin.

A refund address protects you: if the swap does not go through, your coins go back to your address. By default coins do not sit on our balance, and the personal fields of an order, meaning addresses and hashes, are deleted automatically 24 hours after it completes. Your swap history is stored only in your browser. If you have a question, support chat is on every page: the swap code is enough, and you talk to the people who build the service.

If you hold dollars in stablecoins, you can exchange USDT TRC20 to Monero directly, without buying bitcoin first. And if selective transparency suits you better, buy Zcash with bitcoin and use shielded addresses.

FAQ

What is an unhosted wallet?

It is a self-custody wallet: the owner holds the keys, not an exchange or a bank. Hardware wallets and mobile or browser wallets where you keep the seed phrase yourself all count.

Do I have to report a transfer to my own wallet in the US?

There is no separate reporting for such transfers: the 2020 rule that would have required it has been withdrawn. Exchanges still verify customers, keep records and may file suspicious activity reports under the general rules.

Are crypto mixers illegal in the US?

The withdrawal neither bans nor legalizes them: the proposal was about reporting by banks and exchanges. Individual services can still be hit by OFAC sanctions, and operators who act as an unlicensed money transmitter remain liable under the law.

Can the withdrawn rules come back?

Yes. FinCEN kept the right to act further, and Coin Center warns that the authority to issue similar rules remains. A new proposal would have to go through public comment again.

Does this apply to other countries?

No, the decision applies only in the US. Brazil did the opposite and introduced reports on transfers of $10,000 or more to self-custody wallets from October 1, 2026. In the EU the Travel Rule applies, and when you send to your own wallet a service may ask you to prove the address is yours.

Is it legal to own Monero in the US?

There is no federal ban on owning or swapping Monero. Some exchanges do not list privacy coins, but that is their own policy. Gains from swaps are taxed the same way as with any other crypto.
