ASUSDF, issued by Aster, is a NAV-accruing yield token on the Aster Earn platform representing a staked position in the fully USDT-collateralized USDF stablecoin and accruing returns from underlying delta-neutral strategies [S1][S2].

Holders stake USDF, the fully collateralized stablecoin pegged 1:1 to Tether USDt (USDT), to receive ASUSDF, whose yield derives from delta-neutral hedging strategies of long spot and short perpetual futures earning funding rates, trading fees, and interest-rate differentials [S3][S4][S5]. Profits accumulate weekly and are distributed to the ASUSDF contract, reflected in its net asset value (NAV) rather than by rebasing, with advertised returns of up to approximately 30% APY [S1][S5]. ASUSDF mint and withdrawal carry no fees [S4][S2].

Aster, the operator named only as Aster with no registered corporate entity disclosed, offers ASUSDF as an unregulated DeFi product governed by the laws of Hong Kong, with disputes resolved by arbitration administered by the Hong Kong International Arbitration Centre (HKIAC) [S6]. The holder's claim is a staked, NAV-accruing position derived from a USDF claim redeemable for USDT [S3][S4]. Users must be at least 18, and persons located in the United States, Canada, United Kingdom, China, Russia, and other prohibited or sanctioned jurisdictions are excluded, with discretionary identity verification [S6]. Reserves backing USDF are held by custodian Ceffu and deployed into delta-neutral positions [S4][S5].

USDF and ASUSDF are deployed as ERC-20-style smart contracts on BNB Chain [S2]. Holders deposit USDT to mint USDF 1:1, then stake USDF to mint ASUSDF on Aster Earn [S4][S5]. ASUSDF withdrawals are subject to a roughly two-hour waiting period followed by a separate claim step, and weekly yield is reflected in NAV [S4][S2][S5].
