Internet browser company Brave raised $35m from its initial coin offering (ICO) in less than 30 seconds.
It is understood to be the largest amount ever raised through an ICO.
Founded by former Mozilla chief executive Brendan Eich, Brave is a free web browser that claims to block website trackers and invasive internet advertising.
ICOs work by selling investors cryptocurrency. Rather than using an existing cryptocurrency such as bitcoin, Brave chose to create its own currency, dubbed the Basic Attention Token (BAT).
Brave said it would use the proceeds of the ICO to further develop its platform.
