Introducing KAST Earn: Your Money Should Work Harder Than You Do

You're always growing; your money should be too.

Now, with KAST Earn, it can.

Just deposit money into a vault, powered by Gauntlet, and earn yield on your deposits through onchain lending.

Your funds stay fully flexible, and 100% onchain.

You stay in control at all times and can deposit or withdraw whenever you want. Your USD can earn while you focus on everything else.

How to Earn Yield on USD

When you deposit USD, your funds go into the Gauntlet USD Alpha vault, a risk-optimized onchain vault designed to generate real, sustainable yield.

We've partnered with Gauntlet because they’re one of the most trusted risk managers in crypto, with 8 years experience building quantitative decentralized finance (DeFi) strategies. They know their stuff.

The USD Alpha vault prioritizes long-term, risk-adjusted returns over short-term incentives, and actively adapts as markets change.

As of the time of writing, the vault manages $73.8M in TVL with a variable APY between 4-9%.

Once deposited, your capital is:

• Deployed across top-tier DeFi lending protocols
• Actively rebalanced by Gauntlet’s quantitative models
• Continuously compounding through Vault Share tokens

Your earnings are reflected in the value of your Vault Shares and realized when you move funds back to your KAST Spending Account.

What Should You Know?

Is the yield fixed?

No. APY is variable and changes with real-time market conditions.

Can I access my funds anytime?

Yes. There are no lockups. You can deposit or withdraw whenever you want.

Who manages the strategies?

Gauntlet runs and optimizes the vault using institutional-grade risk controls.

What’s the current yield?

The APY is variable between 4-9%, and moves up or down as markets shift.

Custody, Fees, and Risk

Your funds stay in your onchain smart wallet, always under your control. You receive Vault Share tokens so you can clearly see what you own.

Your yield comes from onchain lending strategies and includes smart contract and liquidity risk. You keep 100% of the yield, since KAST charges no fees.

Built for Earning.
