Cyber: Tudou Guarantee Marketplace Halts Telegram Transactions After...

A Telegram-based guarantee marketplace known for advertising a broad range of illicit services appears to be winding down its operations, according to new findings from Elliptic.

The blockchain intelligence company said Tudou Guarantee has effectively ceased transactions through its public Telegram groups following a period of significant growth. The marketplace is estimated to have processed over $12 billion in transactions, making it the third-largest illicit marketplace of all time.

"Other parts of Tudou Guarantee, such as its gambling operations, continue to function, so it remains to be seen whether this represents the first stages of a full shutdown or a pivot away from fraud-related activity," the company said.

Tudou Guarantee is just one of the many Telegram-based marketplaces serving cyber fraudsters, the others being HuiOne Guarantee and Xinbi Guarantee, which collectively engaged in over $35 billion in USDT transactions. Thousands of channels associated with both services were shuttered by Telegram last year.

The marketplace has since emerged as a leading platform, prompting merchants who previously sold through HuiOne Guarantee to migrate to Tudou Guarantee, offering stolen personal data, money laundering services, scam infrastructure like fraudulent investment platforms and phishing websites, and software programs to facilitate face swapping, voice cloning, and deepfake-powered impersonation during video calls with victims.

Research from Chainalysis published in November 2025 has identified that scam technology vendors collectively received at least $375.9 million in cryptocurrency in 2024, with artificial intelligence (AI) service vendors witnessing a 1,900% compound annual growth rate from 2021 through 2024, enabling scammers to forge realistic identities, generate convincing content, and scale their operations.

The migration was no coincidence as HuiOne acquired a 30% financial stake in Tudou Guarantee in December 2024, setting up the latter as a key fallback for Huione-affiliated vendors.

Elliptic's Founder and Chief Scientist, Tom Robinson, told The Hacker News that Xinbi Guarantee has recovered and grown following Telegram's intervention, and that there are a similar number of markets still in operation. "After shutting down HuiOne Guarantee, Telegram is no longer taking any action against these scam marketplaces. There's no need for them to move to other messaging platforms," Robinson added.
