Kast Launches Stablecoin Business Platform with Up to 8% APY

Kast has launched its stablecoin-based business platform, KAST Business, which offers accounts, cards, transfers in more than 20 currencies, and returns of up to 8% APY across over 170 countries.

The platform combines fiat accounts, stablecoin deposits, virtual cards, and local currency payouts, allowing companies to earn up to 3% cashback on card spending. Kast operates as a fintech rather than a bank, using licensed partners for regulated services.

Businesses can receive fiat through virtual accounts supplied by regulated partners and fund their accounts with supported stablecoins and other crypto assets. The platform supports local payouts in more than 20 currencies, giving internationally distributed teams an alternative to managing separate bank accounts and payment services.

The company plans to add between 1,000 and 5,000 active businesses to KAST Business by the end of 2026, following its $80 million Series A funding round in March at a reported valuation of $600 million.
