Revolut has said it will match all donations made by users to the Red Cross Ukraine appeal.
Nikolay Storonsky, CEO of the digital banking app made the announcement in a blog post.
"For every pound or euro or złoty or franc donated by a Revolut customer to the appeal, Revolut will donate the same again, up to £1.5m," he said.
Yesterday, Revolut confirmed that users around the world had donated more than €1m in 24 hours.
On Friday, the company enabled customers to make instant donations to support the victims of the war.
It said the funds will be used for humanitarian aid, and first aid for those affected by the invasion.
It said said 100% of donations go straight to the charities, with no transaction fees or charges for any donations to charity.
"Communities in Ukraine have been bearing the brunt of eight long years of conflict," the International Red Cross said in a statement on their website last week.
"Even before recent developments, this is a conflict that hits people daily on personal, psychological and emotional levels, bringing death, injury and separation from loved ones, as well as the huge mental toll of ongoing violence and insecurity," the statement said.
To date, Revolut has enabled instant Red Cross donations for users in Ireland, the UK, Lithuania, Poland, Switzerland, Portugal and Singapore.
It said more countries will be added to that list in the coming days.
"At this critical moment, our support of the Red Cross in its vital humanitarian efforts enables millions of people worldwide to instantly donate to those affected by the invasion of Ukraine," said Christopher Guttridge, head of Revolut's donations team.
"We asked our customers to show that our hearts and hands are with those impacted by the ongoing crisis in Ukraine - and they have responded with incredible generosity," he added.
Revolut also announced on Friday that it has waived fees for all remittances to Ukraine - allowing its global customers to send money at no cost to banks in the country.
