KAST launches Earn Vaults to bring high performance Stablecoin yield to users around the world
KAST has launched Earn Vaults with DeFi risk manager Gauntlet, letting users earn 5-9% rate on USDC and USDT with no lock-ups and spend the balance with their KAST Card.

- KAST has partnered with Gauntlet, the industry's leading decentralised finance (DeFi) risk manager, to launch KAST Earn Vaults - a new way for users to earn yield on their stablecoins without sacrificing liquidity or usability.
- The first Earn Vault integrates the Gauntlet USD Alpha Vault, offering a competitive 5-9% rate on USDC and USDT, with multi-chain optimisation and no lock-ups, allowing users to keep full flexibility over their funds.
- The launch advances KAST's mission to modernise everyday banking with a stablecoin-powered alternative allowing customers to spend, send, and save.
KAST, the global financial platform built on stablecoin rails, today announces the launch of KAST Earn Vaults, a stablecoin yield product that allows users to earn on their stablecoin balance. The product is powered by Gauntlet as KAST adds high performance yield with institutional grade risk management for its users as it seeks to build an all-in-one neobank for the stablecoin era.
The Gap in Everyday Banking
The launch of KAST Earn addresses a critical gap in global finance. While traditional banks often offer minimal interest rates that can fail to keep pace with inflation, KAST Earn Vault enables users to put their stablecoins to work on-chain - combining the earning potential of DeFi with the simplicity users have come to expect from fintech products. One-click deposits, no gas fees, and no lock-ups remove the complexity for the user.
Built With Gauntlet
The partnership brings institutional grade risk management and high performance yield to KAST users worldwide. Founded in 2018, Gauntlet manages risk for more than $42 billion in assets across leading DeFi protocols with over $2 billion currently deployed in its self custodial vault strategies. Gauntlet's models are trusted by major institutions, including Coinbase and Gemini.
How the Vault Works
Through the Gauntlet USD Alpha Vault, which optimises for the highest yield possible within strict safety parameters, KAST customers can earn 5-9% rate on USDC and USDT. Capital is automatically rebalanced across Base, Arbitrum, Optimism, and Ethereum Mainnet to capture the most competitive rates in real time, while operating within strict, continuously stress tested risk parameters.
Earn While You Spend
What sets KAST apart is the integration of Earn Vaults with the KAST Card, creating a seamless loop between saving and spending stablecoins. Funds earning yield until the moment a purchase is made, allowing users to spend their savings at over 50 million merchants worldwide across 150+ countries. This provides a practical alternative to traditional banking for people seeking USD-denominated savings with both liquidity and returns, particularly in high inflation regions.
We're building the financial infrastructure for the stablecoin-native economy, and our partnership with Gauntlet is foundational to that mission. We've designed KAST Earn to deliver what traditional banks can't. A sustainable, USD pegged yield with complete flexibility. Our users earn yield while they sleep and can spend it on coffee the next morning with their KAST Card. KAST users do not have to choose between returns, safety, and usability - they get all three.

What Comes Next
The Gauntlet USD Alpha Vault is the first step in KAST's Earn roadmap, with plans to add vaults for users to earn yield on BTC, ETH, and SOL. Additionally there are ambitions to offer a range of risk adjusted options for different user preferences, from conservative savers to growth-oriented investors.
