The darknet, also known as the dark web, is a concealed section of the internet that's inaccessible via standard search engines. You can only access it using special software, settings, or authorization. This area comprises websites and content that are purposely kept hidden from public view.
Accessing darknet requires using Tor Browser, a special web browser that routes your internet traffic through a global network of relays managed by volunteers. This way, it becomes very difficult to trace which websites you're visiting, and these sites won't know where you are located.
When visiting the dark web, use a secure browser like Tor, do not reveal any of your personal information, and don't open suspicious files or links to stay safe.
The Darknet is often utilized for secure communication, discreet information or file sharing, anonymous research without identity exposure, and occasionally for engaging in illicit activities. It is also recognized for hosting underground black markets(darknet markets), whistleblowing platforms, and discussion boards that champion freedom of speech.
While accessing Darknet Markets themselves is typically not against the law in most places, engaging with illicit goods within them is generally considered a crime. On the other hand, some people might visit Darknet Markets for lawful purposes such as research, journalistic work, or simply to explore online communities. It's essential to know the local laws regarding online activities, and be cautious when using these platforms to avoid any potential issues.
Onion addresses can change because of key rotation, DDoS mitigation, takedowns, migrations, or compromise. Old links and bookmarks can go stale, so verify the current address through a trusted source and record the date you checked it.
Monero (XMR) is a privacy-focused cryptocurrency. Many darknet markets accept or prefer it because transactions are designed to obscure sender, receiver, and amount, though no system is perfectly anonymous in every context.

Treasury Cuts MEXC Off From U.S. Banking Over $16B in Illicit Flows

On 6 November, FinCEN ordered U.S. financial institutions to stop processing funds transfers involving MEXC Global. The Treasury Department says the exchange handled at least $16 billion in transactions tied to Iranian, North Korean and Russian sanctions evasion, cybercrime and darknet market activity between May 2021 and May 2026.

The mechanism matters. This is not a sanctions designation of MEXC and it does not seize its assets. It is an order under section 9714(a) of the Combating Russian Money Laundering Act, and it cuts the exchange off from the U.S. banking system: no U.S. bank or money transmitter can move funds to or from MEXC. The order takes effect 30 days after publication in the Federal Register. MEXC still exists. It just loses its dollar rails.

What the $16 billion is made of

The Treasury release breaks the figure down. Roughly $1.5 billion is tied to Russian sanctions evasion, including $232 million in direct transactions with U.S., EU and UK-sanctioned entities. FinCEN says MEXC was still processing transactions with Garantex and its successor Grinex as recently as June 2026, more than four years after Garantex was designated. It also cites $26 million linked to the sanctioned A7 network and almost $200 million connected to the A7A5 stablecoin.

On the Iran side, the order alleges about $1 billion in direct transactions with more than 40 identified Iranian crypto exchangers, some of them sanctioned, and about $22 million for the Central Bank of Iran and the IRGC's Qods Force. The release also names ransomware and scam payments and "Russian and other darknet market activity" as part of the overall flow. That last line is why this belongs on a site about darknet markets: the Treasury is treating a top-20 exchange as a chokepoint for the same money that moves through market escrow and vendor wallets.

For scale, Treasury says MEXC was founded in 2018, processed more than $1 billion a day as of September 2026, and held about $5 billion in reserves. It offers more than 50 currencies and 3,000 tokens. DeFiLlama put its total assets at about $4.48 billion on Friday, which is in the same neighbourhood.

Why now

The order is part of Operation Economic Outcast, a Treasury campaign launched in August that targets entities helping Iran evade sanctions. It has already hit a maritime fraud network and eight Canadian money services businesses, both on 6 November. The MEXC action is the largest crypto-specific move in that run so far.

MEXC did not respond to a request for comment from Cointelegraph before publication. I did not find a public statement from the exchange either. That silence is not unusual at this stage, but it leaves the Treasury's account uncontested for now.

What it changes for users

For most people outside the U.S., the immediate effect is limited. The order binds U.S. financial institutions, not MEXC's offshore operations, and it does not by itself freeze customer balances. The practical damage is at the on-ramp and off-ramp: dollar deposits and withdrawals through U.S. banks and payment processors become much harder, and corresponding banks may become more cautious about any MEXC-linked flow.

It is also a reminder that exchange access is a policy variable, not a constant. The same pattern played out with KuCoin, which Canada's Fintrac linked to transactions for Canadian darknet markets in a 2025 compliance case. Exchanges that serve a broad international customer base, including privacy-conscious users, are the ones most exposed to this kind of order.

FinCEN's order is at the link below, along with the Treasury release and the reporting I used. The Federal Register publication will start the 30-day clock.
