Blockchain payments startup Ripple has joined an alliance comprised of almost 1,000 major U.S. companies and CEOs calling for calm and fairness in Tuesday's presidential election.

The Civic Alliance now has 993 member firms with an employee count totaling more than 5 million, according to its website.

"We believe voting should be safe and accessible to everyone, everywhere. That's why Ripple is 100% in #ForDemocracy with @CivicAlliance," Ripple said in a tweet Tuesday.

Some of the country's largest companies are supporting the Civic Alliance effort, including Microsoft, Twitter, Deloitte, Facebook, PayPal and others. The group has committed to offer paid leave for employees, allowing them time to go out and vote, as well as assist at polling stations on Nov. 3.

"As business leaders, we're committed to strengthening our democracy by encouraging nonpartisan voter participation," the alliance's website reads.

While not referenced directly by the alliance, incumbent U.S. President Donald Trump has sought for months to undermine some election processes such as mail-in voting, seen by his campaign as favoring the Democrats. On Monday, he heavily criticized a decision by the Pennsylvania Supreme Court to allow the commonwealth's extended count of mail-in ballots postmarked by election day.

Some Trump supporters have also been taking to the streets in truck convoys and have reportedly disrupted voting in some areas.

Republicans have also raised concerns of left-wing violence if Joe Biden does not win. The National Guard is said to be on standby in case of unrest around the election.

"Growing civil unrest, and polarizing politics are challenging our democracy in new ways," the Civic Alliance said.

The group's CEOs statement calls for "safe access to the polls for all voters," for election officials to be recognized as the "trusted source for certified results" and "patience" as all votes are counted.
