# apxUSD apxUSD is Apyx’s synthetic dollar backed by a diversified basket of low-volatility, variable-rate, preferred shares issued by industry leading Digital Asset Treasuries (DATs). The same mechanism that underpins apxUSD also enables apyUSD, a savings asset that accrues rewards from dividends generated by the DAT preferred equity backing apxUSD. apyUSD is designed as the first Digital Credit savings asset, bringing offchain dividend income onchain for programmatic distribution. apxUSD is intended to be used as both collateral and a quote asset across DeFi and CeFi, with long-term demand driven by utility rather than short-term incentives. ### Collateral Allocation The collateral backing apxUSD is dynamically allocated across preferred shares issued by various DATs. The basket rebalances subject to issuer concentration, liquidity requirements for efficient execution, and coverage requirements that keep apxUSD overcollateralized. In redemption scenarios, the protocol liquidates preferred shares to USDC to settle redemption obligations; holders do not receive preferred shares directly.

Users can compare the collateral position against the apxUSD supply in real time through the dashboard. 3. **Cross-Market Arbitrage** Apyx may engage in arbitrage across multiple spot markets involving apxUSD to support its peg. Similar opportunities are also available to users whitelisted, allowing them to mint or redeem apxUSD to capture price differences across markets. 4. **Derivative-Based Tail Hedging Strategies**\ Apyx may deploy low cost, tail hedging strategies to reduce volatility in volatility spike scenarios where the preferred shares trade down significantly.

Redemptions are settled in USDC; the protocol does not transfer preferred shares directly to redeeming participants. In a drawdown scenario, the protocol would sell preferred share positions to USDC to facilitate redemption. apxUSD grows through a demand-driven flywheel. When apxUSD trades at a premium relative to its backing, minters may mint additional apxUSD and purchase more preferred equity collateral. This expands the collateral base, deepens liquidity, and increases the dividend capacity that supports apyUSD. General users can acquire apxUSD through permissionless external liquidity pools and swaps. Eligible participants in permitted jurisdictions who are whitelisted Apyx, such as institutional partners and market makers, may mint and redeem apxUSD through the protocol's designated issuance and redemption pathways. Mint and redemption requests are processed quickly. To ensure stability, the protocol maintains a liquidity buffer sized against the largest historical TVL drawdowns observed in comparable stablecoins. Note that liquidity may be more limited outside of traditional trading hours and on weekends, though the buffer remains available at all times. apxUSD is designed to trade close to $1 at all times. To support this, the protocol will incentivize an apxUSD/USDC liquidity pool on Curve and aims to secure CEX listings where users can trade apxUSD against stable and dollar pairs. When apxUSD trades at a premium relative to its backing, minters may mint additional apxUSD and purchase more preferred equity collateral. This expands the collateral base, deepens liquidity, and increases the dividend capacity that supports apyUSD. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
