Stark Bank aims to serve Brazil's cryptocurrency startups.
The online-only bank plans to position itself as a banking provider for crypto startups, as traditional lenders are still reluctant to support the sector.
Stark Bank works with 52 firms focused on digital currencies and blockchain technologies, providing payment processing and other services.
The bank raised $45 million in a Series B funding round, backed by Jeff Bezos, and aims to capture market share from traditional corporate banks in Brazil.
