TLDR
US authorities have sanctioned Xinbi Guarantee, a major crypto-based scam marketplace, and frozen over $52 million in related digital assets.
- Xinbi, a Chinese-language crime marketplace, was designated a transnational criminal organization and cut off from the US financial system after processing over $24 billion in crypto and fiat.
- The operation froze or restrained more than $52 million in crypto, with help from Tether and blockchain analytics firms, and targeted the Telegram infrastructure used to run large-scale scams.
- This raises the bar on sanctions compliance around stablecoins and OTC flows, and similar crackdowns on other scam-linked crypto services are likely.
Deep Dive
1. Xinbi Marketplace Sanctioned
The US Treasurys OFAC has sanctioned Xinbi Guarantee, describing it as a significant transnational criminal organization that supported crypto scams, money laundering and other illicit activity across Southeast Asia, after it allegedly processed over $24 billion in crypto and fiat since 2022. Reports link Xinbi to North Korean hackers and entities tied to the already sanctioned Prince Group, making it a key hub for laundering proceeds from major exchange hacks and pig butchering scams.
The sanctions extend to two supporting tech firms, Singapore-based SafeW Technology and Cambodia-based Anwen Technology, which reportedly ran an encrypted messaging app and the XinbiPay or NewPay wallet used to move funds through the marketplace.
Xinbi is not a normal exchange but an infrastructure layer for organized crime, so regulators are now attacking the marketplace itself as well as its technical partners.
2. Seizures, Stablecoins And Infrastructure
In a coordinated move, the US Justice Departments Scam Center Strike Force seized two Xinbi-related wallets holding about $12 million and obtained court orders restraining 47 more, bringing the total restrained or seized amount to over $52 million. Authorities also secured orders to take over Telegram channels that hosted Xinbis marketplace, disrupting its communications layer.
Stablecoin issuer Tether helped freeze large amounts of USDT connected to Xinbi, with investigators estimating that most of Xinbis volume ran through USDT on networks such as TRON, while Xinbi later tried to shift to USDD, a more censorship-resistant stablecoin. Blockchain analytics firms like Elliptic and Chainalysis traced flows through Xinbi, highlighting how on-chain forensics, issuer freezes and legal seizures now work together to hit illicit crypto infrastructure.
Centralized stablecoins and messaging platforms are increasingly used as enforcement levers, so addresses and services linked to sanctioned entities can be frozen or shut down quickly.
3. Compliance Pressure And What To Watch
US sanctions mean all Xinbi-related property in US jurisdiction is blocked and US persons are generally prohibited from transacting with Xinbi, SafeW or Anwen, while the UK has already imposed similar measures. This signals continued pressure on Southeast Asian scam compounds and on the guarantee marketplace model that previously replaced Huione Guarantee.
For legitimate users and businesses, the case reinforces a trend toward stricter sanctions screening of crypto transfers, especially for stablecoins, OTC desks and high risk counterparties. Future enforcement may focus on other guarantee-style platforms, unlicensed OTC brokers and privacy-preserving stablecoins that scam networks migrate to after USDT freezes.
The more regulators target crypto crime infrastructure, the more exchanges, OTC desks and wallet providers are likely to tighten sanctions checks, raising the operational bar for both illicit actors and compliant users.
Conclusion
Sanctioning Xinbi and restraining over $52 million in crypto shows US and allied authorities shifting from chasing individual scammers to dismantling the marketplaces and payment rails that support industrial scale fraud. That approach relies heavily on centralized chokepoints such as stablecoin issuers, messaging platforms and exchanges, and signals that sanctions enforcement in crypto is moving closer to traditional finance in both scope and tools.
