Origins of apxUSD
apxUSD is a synthetic dollar token issued by the Apyx protocol, which describes itself as the first dividend-backed stablecoin protocol. It launched on Ethereum mainnet in February 2026.
Around the same time, Apyx completed two strategic funding rounds that reportedly had no venture capital participation. Nasdaq-listed DeFi Development Corp. (DFDV) is a core strategic partner.
Dividends Turned Onchain
Apyx buys preferred shares issued by Digital Asset Treasuries (DATs), which are publicly listed companies holding digital assets on their balance sheets, and holds them as collateral. These shares pay monthly cash dividends, and the protocol converts those offchain cash flows into onchain yield.
apxUSD is designed to be backed by more than 100% collateral in these preferred shares. Instruments such as STRC, a variable-rate perpetual preferred stock issued by Strategy, are cited as examples of the collateral.
A Two-Token Design
apxUSD itself does not pay yield and is meant to serve as a liquidity and collateral asset across DeFi and CeFi. Yield is delivered through a separate token, apyUSD.
apyUSD is an ERC-4626 vault that users receive when they lock apxUSD. As dividends are distributed, apyUSD gradually increases in value relative to apxUSD.
Strengths and Risks
A distinctive feature is that yield is tied to preferred equity dividends from listed companies rather than lending or token emissions. The protocol says it manages risk through daily NAV reporting, auto-rebalancing based on issuer concentration and liquidity thresholds, stress testing, and a protocol-owned liquidity buffer.
However, collateral value depends on digital asset prices, preferred share markets, and issuers' ability to keep paying dividends, and there are custody and regulatory risks tied to offchain assets. A brief depeg from the dollar was reported in June 2026.
