Twitter co-founder Jack Dorsey is committing $1 billion of his equity in the mobile-payments company Square to coronavirus relief efforts. 

In a series of tweets on Tuesday, Dorsey said he was contributing roughly 28% of his net worth to the Start Small Foundation to “fund global COVID-19 relief.”

He added, “After we disarm this pandemic, the focus will shift to girl’s health and education, and ”

Dorsey also vowed to “operate transparently” and update a list of how the funds are distributed, “Why the transparency? It’s important to show my work so I and others can learn.”

He also explained his reason for the causes he said he would contribute money to after the pandemic, “Why UBI and girl’s health and education? I believe they represent the best long-term solutions to the existential problems facing the world. UBI is a great idea needing experimentation. Girl’s health and education is critical to balance.”

Since the outbreak of the coronavirus, several celebrities have said they would contribute millions of dollars to help provide relief to those hard hit by the virus.

According to the latest data, the U.S. has 386,817 confirmed cases of the coronavirus.Â
