DeFi & Yields ·
Plasma, a stablecoin neobank offering self-custody and card functionality across 150–180+ countries, has demonstrated rapid growth in spending volume, rising from $3.4 million in May 2026 to $19.9 million by August 2026. According to reports, August alone saw 149,000 transactions and 26,000 active cards in use. The platform bundles stablecoin holdings with Visa and Apple Pay/Google Pay integration, alongside cashback rewards reaching up to 10% on select categories and approximately 5% yield on idle balances.
The architecture's appeal centers on where user funds reside after a card top-up. Unlike centralized card pools, Plasma's non-custodial model keeps assets in user-controlled wallets, with card spending executed directly from those wallets rather than through a shared contract layer. This distinction gained prominence following exploits affecting centralized card-balance architectures, positioning non-custodial design as a post-exploit security standard among competing card issuers that similarly retain funds in personal vaults or account-based structures.
Outstanding questions include the sustainability of monthly spend growth beyond August, the long-term composition and retention rate of the 26,000 active cardholders, and whether the cashback and yield offerings remain competitive as the platform scales.
