Payment giant Klarna, a Swedish fintech and NYSE-listed company, has announced the launch of "KlarnaUSD," its first stablecoin, on the Tempo blockchain. Tempo is a payment-focused blockchain network jointly incubated by Stripe and Paradigm. This strategic move aims to leverage Tempo's infrastructure to facilitate faster and cheaper cross-border payments for Klarna's massive user base of 114 million customers. By integrating stablecoin rails, Klarna is targeting the $27 trillion annual transaction market, representing a significant "rail-replacement" trade where traditional fintech services directly adopt blockchain technology for efficiency. [Update 1] New reports highlight that this initiative marks a major integration of traditional fintech into the blockchain sector, specifically targeting the $27T transaction market to improve payment speed and cost efficiency for its global customer base.
