ChainThink reports that on July 31, according to Decrypt, the U.S. Treasury’s OFAC sanctioned two Iranian companies on Wednesday, alleging they were involved in compelling commercial vessels to purchase "insurance" backed by the IRGC to transit the Strait of Hormuz.
Among them, the HormuzSafe Marine Services Authority, developed by Iran's Ministry of Economic Affairs and Finance, accepts payments in Bitcoin and other digital assets. OFAC stated that this model is one of the methods used to circumvent Western sanctions.
In April of this year, the Financial Times reported that Iran was planning to impose a cryptocurrency "toll" on transiting vessels, a claim met with skepticism by some blockchain analysts at the time. In the same action, the U.S. Department of the Treasury also sanctioned eight Iranian crude oil tankers and their operators;
Since January of this year, over a hundred vessels from the "shadow fleet" have been sanctioned.
