Your principal is safe.

Deposit USDC into Treasury. Your principal is locked and cannot be spent under any circumstances. Only accumulated yield is available for use.

3.5% APY on idle funds.

Yield accrues continuously on your deposited USDC. No lockup periods, no minimum deposits, no tiered rates. Everyone gets the same APY.

Zero fees. Period.

No management fees, no withdrawal fees, no performance fees. The yield you earn is the yield you keep. We make money on settlements, not on your deposits.

Deposit flow: fund, earn, spend yield.

Transfer USDC into your Treasury account. Yield begins accruing immediately at 3.5% APY. When you want to use earnings, withdraw yield to your operational wallet. Principal remains locked. The separation between principal and yield is enforced at the smart contract level — not a policy, a guarantee.
