Iran this week placed its first official import order in a cryptocurrency.
The contract is worth $10 million, according to the semi-official agency Tasnim.
It is said to be a first step in circumventing American sanctions that have paralyzed the Islamic Republic's economy.
Which digital money was used in the transaction remained open.
"By the end of September, the use of cryptocurrencies and smart contracts in foreign trade with destination countries will be widespread," an official at the Ministry of Industry, Mines and Trade wrote on Twitter.
Trading digital assets aims to bypass the dollar-dominated global financial system and allow trades with other countries also restricted by American sanctions - such as Russia.
According to a study published last year, 4.5 percent of the dominant cryptocurrency Bitcoin was mined in Iran.
One reason for this is the comparatively cheap electricity, since mining uses a lot of electricity.
Digital mining could help Iran make hundreds of millions of dollars.
However, the prices of cryptocurrencies such as Bitcoin fluctuate greatly and have not yet established themselves in payment transactions.
In 2018, then US President Donald Trump withdrew from the 2018 nuclear deal with Iran and reintroduced tough sanctions.
Tehran then began violating the conditions about a year later.

The European Union (EU) has presented a "final text" to restore the international pact of 2015, EU foreign policy chief Josep Borrell said on Twitter on Monday.

It was not yet possible to say whether a breakthrough is within reach.
The United States showed itself ready for a speedy conclusion.
Iran pointed to the need for further internal consultations.
