I. The spark: Chongqing Vice Mayor Jiang Duntao falls

Who is Jiang Duntao? Vice Mayor of Chongqing. After his fall, the tone from Chongqing’s disciplinary inspection and supervision authorities clearly changed.

Why? Because behind Vice Mayor Jiang’s case is a long-standing official interest ecosystem, where some use USDT to get around doors and launder money. This breakthrough isn’t from traditional discipline inspection or supervisory covert investigations, but—someone used USDT, with clear on-chain receipts.

It directly exposed the internal corruption chain.

II. Chongqing Mayor Hu Henghua is under investigation

The news came out on March 20, with the Central Commission for Discipline Inspection and National Supervisory Commission’s website directly announcing: Hu Henghua is suspected of serious violations of discipline and law, and is under investigation.

That afternoon, Chongqing Municipal Party Committee held an emergency standing committee meeting, chaired by Party Secretary Yuan Jiajun, with a unified stance: “Resolutely support the decisions of the Party Central Committee.”

On the surface, it was swift and resolute, but look deeper: the mayor is under investigation, and it’s during his term—this is no small matter. Hu Henghua’s rank is significant; he was transferred from Hunan in 2019, previously a Standing Committee Member of Hunan Provincial Party Committee and Executive Vice Governor, having served in Chongqing for over a term. On the day he was taken down, Chongqing made a public announcement directly.*

III. Businessman Lin Kechuang is taken away

The key point: after Hu Henghua’s investigation, the scope of the disciplinary and supervisory control quickly expanded. On April 14, Lin Xiucheng’s son-in-law—businessman Lin Kechuang—was taken away by relevant authorities.

Then, after Hu’s cold wallet was controlled, authorities traced the funds from his USDT wallet address, easily tracking the flow to six other cold wallets owned by Lin. According to sources, Lin paid a total of 30.8 million USDT to Hu, roughly 210 million yuan, but among them, 10 million USDT (about 67.5 million yuan) was “exchange fee”—a middleman turnover cost to mask the transaction.

IV. Chongqing Municipal Party Standing Committee Member Luo Lin is under investigation

On April 17, the Central Commission for Discipline Inspection and National Supervisory Commission announced again—Chongqing Municipal Standing Committee Member and Liangjiang New Area Party Secretary Luo Lin is suspected of serious violations of discipline and law.

Hu Henghua fell on March 20, Luo Lin on April 17, less than a month apart. After controlling Hu Henghua’s cold wallet, authorities traced the on-chain funds and precisely located Luo Lin.

Sources say Luo Lin was already taken away on April 14, with the official announcement on April 17. What’s the difference of these three days? It’s information control—because investigations need to race against time and evidence destruction. Luo Lin’s cold wallet was hidden with a third party, but was directly seized by authorities.

This means every transaction stored in USDT was fully traceable on the blockchain. A tiny cold wallet, the size of a fingernail, brought down half of Chongqing’s officialdom—from the mayor to the standing committee members, to businessmen.

V. "Red-top female lawyer" Peng Jing is taken away
