apxUSD (APXUSD)

apxUSD is a synthetic dollar asset issued by Apyx, a protocol that links traditional dividend-paying securities with on-chain stablecoin liquidity. The system is designed around preferred equity issued by Digital Asset Treasury companies, or DATs: publicly listed firms that hold crypto assets on their balance sheets and raise capital through preferred shares. Apyx acquires these preferred shares and uses them as collateral for apxUSD, while the cash dividends generated by the securities support the protocol’s broader yield model.

Unlike a yield-bearing stablecoin, apxUSD is intended to function as the liquid dollar unit within the Apyx ecosystem. It is backed by more than 100% collateral in DAT preferred shares, according to the protocol, and is built for use across decentralised finance and centralised venues where stable dollar liquidity is required. Users who want exposure to the income generated by the collateral can move apxUSD into apyUSD, an ERC-4626 vault token that accrues value as dividend streams are reflected in the vault exchange rate.

Apyx’s structure combines off-chain financial instruments with on-chain token mechanics, making risk management central to the design. The protocol cites daily net asset value reporting, issuer concentration limits, liquidity-based rebalancing, stress testing and a protocol-owned liquidity buffer as safeguards for collateral quality and redemption resilience. DeFi Development Corp., a Nasdaq-listed Solana-focused Digital Asset Treasury, is identified as a strategic partner, highlighting the project’s focus on the growing market for listed companies that hold digital assets.
