“Can a self-custody stablecoin wallet replace the consumer bank account for globally-mobile users without a US SSN?”
Karta started as TryHomz in 2022 and pivoted into a self-custody crypto money app. Its B2B product (business.karta.io) targets Web3 teams, marketing agencies, and freelancers with stablecoin wallets, virtual Visa cards, and crypto-to-fiat payouts.
