Plasma is set to introduce its new banking service, Plasma One, following the mainnet beta launch of its stablecoin blockchain later this month. The service will feature a prepaid credit card offering 4% cashback on purchases and over 10% returns on balances, with support for international payments. Users can fund their cards with stablecoins like USDT, expanding to other options over time, and make payments via physical or virtual cards. The card will be issued by Rain, known for the Avalanche Card, and will use the Plasma blockchain as a payment gateway. Plasma's mainnet testing phase begins on September 25th, with neobanking services to be rolled out in stages. Interested users can join the waiting list on Plasma's website.
