Gauntlet USD Alpha Powers KAST’s Earn Program Bringing Stablecoin Yield to 500K+ Users Worldwide

Key Takeaways

KAST, one of the world’s leading stablecoin neobanks has taken a great leap forward to offer its users the benefits of DeFi without the complexity. KAST powers its Earn product with Gauntlet USD Alpha. Over 500,000 KAST users worldwide can now earn sustainable DeFi yield on their USDC (4.69% as of today).

KAST Earn, powered by Gauntlet USD Alpha, joins a robust product suite that includes the KAST stablecoin credit card, local fiat on- and off-ramp integrations, and more. Gauntlet is DeFi’s premier risk manager and vault curator. Our risk models protect over $48 billion in DeFi TVL across the top protocols in the space, and our yield strategy vaults have over $1.7 billion in user-custodied assets. 

Where the yield comes from: over $1 billion in USDC in Gauntlet vaults

Stablecoin yield powered by DeFi is a highly compelling value proposition that helps ensure users and their funds have all the more reason to maintain their assets on the KAST platform. But DeFi is complex. KAST’s users now have access to a streamlined experience. All powered by crypto’s most vigilant quants. 

How it works: partner with the right risk manager for the job

Gauntlet USD Alpha is the best way to balance capital preservation with sustainable growth for USDC. The strategy taps into select variable and fixed yield opportunities on protocols like Morpho and Pendle across Ethereum mainnet and L2s like Base, Optimism, and Arbitrum. Users pay no gas fees when the strategy rebalances and protocol rewards are autoredeemed and compounded back into the strategy, no manual claims required. Set and forget. The strategy counts over $73 million in capital supplied. 

Other vaults may promise high APYs, but typically these opportunities are temporarily elevated via protocol token incentives, require manual redemption (and gas costs that can add up) paid for by the user, and tend to be highly volatile. We focus on longterm performance and consistency over time.
