The U.S. Treasury Department sanctioned Xinbi Guarantee on September 9, targeting a Chinese-language marketplace it says supplies escrow and other services to cyber-scam operators. The action also designates two companies behind messaging and cryptocurrency-payment applications used by the network.

Treasury says Xinbi has processed more than $24 billion in digital assets and fiat currency since around 2022, primarily supporting transactions in Southeast Asia. That figure describes marketplace activity across both payment types, not a crypto-only total or an estimate of money recovered.

Messaging and wallet providers targeted

The designated companies are Singapore-based SafeW Technology and Cambodia-based Anwen Technology. According to Treasury, Xinbi began migrating merchant and money-laundering networks to SafeW’s encrypted messaging application around June 2025 as law-enforcement scrutiny increased.

Treasury identifies Anwen as the developer of XinbiPay, also called NewPay, a cryptocurrency-payment and digital-wallet application. It says the platform connects criminal syndicates with merchants providing financial services, technology and other supplies.

The department also says the Justice Department’s Scam Center Strike Force seized infrastructure and digital-asset wallets used by Xinbi in a coordinated action.

Cross-border enforcement

The U.S. action follows the United Kingdom’s March 26 sanctions against Xinbi, which British officials described as an illicit cryptocurrency marketplace supporting Southeast Asian scam centres.

The new designations extend enforcement beyond the marketplace itself to providers of its communications and payment tools. Treasury frames those services as core infrastructure supporting the network’s operations.
