What to know:
- U.S. sanctioned a Sinaloa Cartel-linked network moving fentanyl proceeds through crypto rails on May 20, 2026.
- Armando de Jesus Ojeda Aviles led a structured cash-to-crypto system tied to couriers and stablecoins.
- Chainalysis traced layered wallet flows using DEX swaps and centralized exchanges for cash-out routes.
The latest enforcement action by the U.S. Office of Foreign Assets Control (OFAC) targeted a Sinaloa Cartel-linked financial cell operating in cross-border drug finance. The case highlights how Crypto Crime is shifting into structured digital pipelines where physical cash from fentanyl sales is converted into stablecoins.
According to Chainalysis, the couriers had picked up the cash from the United States and shipped it using third parties associated with Armando de Jesus Ojeda Aviles.
Crypto Crime utilized crypto wallets for transactions to bypass banks and carry out transactions quickly without getting noticed. This was consistent with previous cases involving the cartel.
OFAC Pressure On Crypto Crime Financial Operators
The sanctions imposed by the Office of Foreign Asset Control have been imposed to disrupt the workflow involved in this Crypto Crime.
In the center of it all stands Armando de Jesus Ojeda Aviles, who took up the task of laundering money for the Los Chapitos wing of the Sinaloa Cartel after the former person responsible was removed in 2023.

His network has controlled couriers who collected the proceeds of the drug trade in the US and moved them into cleaner jurisdictions.
The Crypto Crime project made sure that the use of physical money did not overlap with the transactions being done digitally, which would make it difficult for the money trail to be traced internationally.
The reason for this was that since everyone involved in the network had access to just a fraction of the entire transaction, it became increasingly difficult to impose the law.

Crypto Crime Flow Traced Through On-Chain Movements
According to Chainalysis Reactor, here is a description of how the proceeds made from the drug trade were laundered in the cryptocurrency world, step by step.
Money from the sale of fentanyl was first delivered to the brokers associated with Ojeda Aviles by couriers. Next, the money was converted into stablecoins, a popular means used for crypto crimes due to their stability and quick transaction processes.
Next, the money would be sent to centralized exchanges, where efforts were made to make the money real. This crypto crime scheme is complex, consisting of multiple layers, but it can still be spotted using blockchain analysis techniques.
The scheme relied heavily on splitting of funds, but repeated wallets could be identified during the process, illustrating the structure of the network.
Monitoring and disruption of Crypto Crime pipelines
The final stage in enforcement focuses on the working relationship between crypto crime and global cryptocurrency liquidity. The utilization of stablecoins is now crucial to the workings of cartel finance due to their ability to transfer funds easily across borders.
In this instance, Chainalysis marked wallet addresses associated with the Crypto Crime network. This assists the compliance officers in knowing their exposure at any one time.
According to the agency, monitoring of these transactions is critical because the Crypto Crime groups tend to reorganize themselves after being sanctioned.
