A bipartisan group of U.S. senators is pushing for tighter sanctions against Venezuela’s state-backed cryptocurrency, known as the petro.

The bill, known as the Venezuela Humanitarian Relief, Reconstruction and Rule of Law Act of 2018, covers a range of areas related to Venezuela, including proposed humanitarian aid to migrants from the country and efforts to support “restoring democracy” amidst its long-running economic crisis.

The bill is sponsored by Senators Bob Mendendez, Marco Rubio, Bill Nelson, John Cornyn, Dick Durbin, David Perdue, Ben Cardin, Ted Cruz, Tim Kaine, Michael Bennet and Patrick Leahy, according to LegiScan. It was first introduced on September 24.

It notably includes a section mirroring an executive order signed by U.S President Donald Trump in March that imposed sanctions on the petro, which Venezuelan President Nicolas Maduro unveiled last last year. The controversial cryptocurrency has drawn criticism and condemnation from some quarters while the government there itself has sought to implement it across a variety of industries. Earlier this week, Maduro said that a public sale of the petro would begin next month.

Yet the Senate bill takes Trump’s executive order a step further, barring U.S. residents from providing “software” to the Venezuelan government as part of its efforts to launch the petro.

“All transactions by a United States person or within the United States that relate to, provide financing for, provide software for, or otherwise deal in any digital currency, digital coin, or digital token, that was issued by, for, or on behalf of the Government of Venezuela are prohibited beginning on the date of the enactment of this Act,” the bill states.
