aptUSD

Your dry powder shouldn’t have to sit idle.

Crypto investors & traders often hold stablecoins while waiting for the next opportunity to deploy capital. But earning yield on that capital has traditionally meant putting it to work across DeFi protocols, lending markets, exchanges, or other strategies that introduce additional platform, counterparty, and smart contract risk.

aptUSD offers a simpler alternative: liquid, zero-fee access to tokenized U.S. Treasury yield.

Backed by a basket of U.S. Treasury bills and cash equivalents, aptUSD is designed for crypto-native investors and traders who want their dollars earning while they wait for their next trade, investment, or opportunity.

There are no staking fees, no unstaking fees, and no unlock period. Hold aptUSD while you’re on the sidelines, earn a predictable payout, and exit when you’re ready to deploy.

How aptUSD Works

alqUSD is the underlying, non-yield-bearing dollar and is designed to maintain a value of $1.00.

Through the Apyx Swap tool, users can swap from USDC to alqUSD to aptUSD in one click to begin earning yield. As Treasury yield accrues, the exchange rate of aptUSD steadily increases relative to alqUSD. Each aptUSD becomes worth more alqUSD over time.

When you want to exit, swap from aptUSD back into USDC, passing through alqUSD with zero fees and zero cooldown.
