The US Treasury sanctioned Xinbi Guarantee, a Chinese-language cryptocurrency platform that funneled $24 billion through a Telegram-based marketplace serving criminal networks across the globe. The Secret Service froze $52.8 million in assets tied to the operation, following blockchain forensics work by Elliptic that traced the flows.
Xinbi called the asset freeze unfair. That’s the standard playbook when sanctions land, deny, deflect, claim persecution. But the Treasury’s designation paints a different picture: a marketplace that didn’t just touch criminal money in passing but existed to serve it at industrial scale.
Telegram as Infrastructure
The platform operated on Telegram, the messaging app that’s become a corridor for grey-market finance from Eastern Europe to Southeast Asia. Xinbi offered escrow services, payment rails, and counterparty guarantees for other criminal networks, the kind of plumbing that turns opportunistic scams into repeatable operations. When your customer base is fraudsters and you’re processing tens of billions, that’s not an accident of client screening. That’s the business model.
Elliptic’s role was central. The blockchain intelligence firm traced transactions across chains, mapped flows to known scam clusters, and handed Treasury the ledger. It’s a familiar pattern: forensics firms do the heavy lifting, agencies follow the trail, sanctions drop. The question isn’t whether the money moved, blockchains don’t lie about that, but whether enforcement seventeen steps downstream does anything to stop the next hub from opening shop under a new name.
$24 Billion, One Marketplace
Twenty-four billion dollars. Not cumulative lifetime volume across a legitimate exchange with some bad actors mixed in. Twenty-four billion through a Telegram-based service accused of operating specifically for criminal networks. The scale dwarfs most DeFi protocols. It’s larger than the total value locked in half the L1s anyone pretends to care about.
The Chinese-language focus is notable but not surprising. Cross-border crypto flows between China and the rest of the world have been a regulatory blindspot for years, carved into the gap between Beijing’s capital controls and the West’s sanctions lists. Platforms like Xinbi set up in that gap, offering liquidity where banks won’t touch the transaction and where counterparties don’t ask questions.
The $52.8 million freeze is a fraction of the $24 billion Xinbi allegedly processed. Some of that capital scattered the moment Treasury’s designation became public; some never sat still long enough to freeze in the first place. What remains is a data point: another crypto crime hub down, blockchain forensics credited with the bust, and the ecosystem wondering how long until the next Telegram channel spins up with a slightly different name and the same tired script.
