Blockchain analysis has exposed four cryptocurrency wallets linked to Hubei Amarvel Biotech, a Chinese fentanyl trafficking organization that operated from Nagoya, Japan, according to evidence from a US court case. The company's executives were jailed in 2025 after investigators uncovered the network's use of digital assets to receive payments from Mexican drug cartels for fentanyl precursor chemicals and to move funds internationally. The findings have intensified scrutiny of Japan's role as a transit hub in global fentanyl smuggling routes, with the wallets showing connections to over 120 transactions involving US-sanctioned entities and suspected financial fraud activity.
Blockchain Analysis Uncovers Four Wallets Linked to Amarvel Operation
The four digital wallets were identified through court evidence from the US case against Hubei Amarvel Biotech, a Chinese chemical manufacturer. Investigators determined the company operated from Nagoya, where it received cryptocurrency payments from Mexican drug cartels and other customers purchasing fentanyl precursor chemicals. The operation also used digital assets to move funds internally and externally, according to the analysis.
One of the identified Tron wallets showed links to suspected financial fraud through transfers involving scam cryptocurrency tokens. Investigators uncovered connections between the operation and a Japanese internet domain, online aliases and businesses associated with China's Hebei province. Amarvel established its Nagoya base in September 2022, according to the records.
Investigators Trace Over 120 Transactions to Sanctioned Entities
Using blockchain records, investigators analyzed transactions involving Amarvel's four wallets after the company established its Nagoya base in September 2022. The review identified more than 120 cryptocurrency interactions with organizations sanctioned by US authorities, indicating the operation was connected to a larger criminal network.
The investigation traced cryptocurrency transfers involving sanctioned Chinese national Xia Fengbing. Independent blockchain specialists concluded the repeated movement of funds to common destination wallets over an extended period provided evidence of a financial relationship between the parties.
