KAST Launches Reserve to Offer 12% Daily Rewards on Spendable Stablecoin Balances

KAST has launched KAST Reserve, a high-yield rewards product offering up to 12% on USD balances. For fintech professionals, this move signals a shift in how stablecoin platforms compete with traditional high-yield savings, leveraging corporate revenue to subsidize yields while maintaining liquidity for global spending, effectively bridging the gap between DeFi returns and traditional banking utility.

What was announced

KAST Reserve is a new rewards-bearing account designed to allow users to build and store USD balances while retaining the ability to spend those funds globally. The product is positioned as a stable, reduced-risk alternative to decentralized finance (DeFi) protocols, specifically targeting users who want the benefits of stablecoins without the complexities of blockchain-native tools. The platform currently supports USD-denominated accounts and global pay-ins and payouts across more than 170 countries.

The reward structure is tiered based on membership levels. Users can earn between 6% and 12% in rewards on their USD Reserve balances. Private members at KAST are eligible for the top rate of 12% on balances up to $200,000. These rewards are funded directly by KAST through its own revenues and corporate balance sheet, rather than through lending or DeFi yield farming. Customer funds are held in stablecoins and treasury equivalents to mitigate market risk. The initial high-reward program is capped at a total of $100 million in deposits. After January 2027, the rates are scheduled to adjust to a lower range of 4% to 8%.

KAST Reserve joins an existing suite of products that includes the USD Prime Vault and Gauntlet Alpha Vault, which are tailored for more DeFi-native users. By contrast, Reserve is built for a broader audience, emphasizing that funds remain spendable even while they are actively earning rewards.

"Reserve provides KAST members a premium service with the best rewards, even beyond the stablecoin market. Our easy-to-use, simple user experience makes stablecoin-powered global dollar accounts, including these rewards, accessible for everyone, not just people accustomed to blockchain. Turning USD balances into actual wealth and spending power is a game changer for our users."

The companies involved

KAST is a financial technology platform that utilizes stablecoin rails to provide modern financial services, bypassing legacy settlement networks. Founded in July 2024, the company has rapidly expanded its footprint to offer USD-denominated accounts and payment services in over 170 countries. KAST operates by partnering with licensed institutions to facilitate global pay-ins and payouts, positioning itself as a bridge between the $260 billion stablecoin market and traditional consumer finance.

The firm has recently focused on aggressive talent acquisition to bolster its regulatory and operational standing, particularly in the North American market. This includes hiring veterans from major industry players like Stripe and Binance, as well as former government officials, to navigate the complex intersection of digital assets and traditional policy. KAST’s business model emphasizes the use of its own corporate balance sheet to incentivize user growth, a strategy designed to offer "premium" financial products that outperform traditional banking yields while maintaining the security profile of treasury-backed assets.

What FF News has reported before

FF News has closely tracked KAST’s expansion and leadership strategy over the past year. In August 2026, we reported on the company’s efforts to scale in the United States with the article KAST Appoints Stripe Veteran Connor Fitzgerald as U.S. General Manager to Drive Market Expansion. This followed a series of high-profile hires, including the recruitment of a former SEC official to lead policy communications and the appointment of former Binance leader Brad Jaffe as Chief Communications Officer. Additionally, KAST has been innovating in the loyalty space, as seen in our coverage of their stablecoin cashback launch, which marked a departure from traditional point-based reward systems.

What this means

KAST is making a bold play for the "high-yield" segment of the market by using its own balance sheet to guarantee returns that significantly outpace traditional savings accounts and even many DeFi protocols. By capping the initial program at $100 million and setting a 2027 expiration for the highest rates, KAST is clearly using Reserve as a customer acquisition tool to build a massive deposit base quickly. This puts pressure on both traditional neobanks and other stablecoin issuers like Circle or Tether to prove their utility beyond simple value storage. The key to KAST's success will be whether they can transition these high-yield seekers into long-term users of their broader payment ecosystem before the rates normalize in 2027.
