Our verdict on Aster USDF
6.5/10Aster USDF suits DeFi users who already hold USDT, want yield without taking directional price risk, and are comfortable with a stablecoin tied to a perp DEX. Its main strength is a simple 1:1 USDT conversion with yield from delta-neutral positions and meaningful TVL. The main caveat is the lack of listed audits and published reserve or redemption detail, so start small and read the docs first.

What is Aster USDF?
Aster USDF is a yield-bearing stablecoin issued by Aster, a perpetuals DEX. DefiLlama says it converts with USDT at 1:1 and that the underlying USDT is used to build delta-neutral positions that back USDF and produce asUSDF yield.
DefiLlama tracks about $113.3 million in TVL for the product on BNB Chain, up 1.1% over seven days, and lists it since 20 November 2024. The Aster homepage states a wider platform TVL of $1.46B, though that covers the whole exchange rather than USDF alone.
On the Aster homepage, USDF is pitched as a way to earn on idle margin while trading. The platform describes itself as non-custodial, with multichain support across BNB Chain, Arbitrum, Ethereum and Solana, and an Aster Chain L1 in development or operation.
The main gaps are audits, reserve reporting and redemption terms, none of which appear.
How Aster USDF works
USDF is a stablecoin issued by Aster. Users convert USDT into USDF at a 1:1 ratio. The underlying USDT is then used to open and maintain delta-neutral positions.
A delta-neutral position pairs holdings so that price moves in the underlying asset largely cancel out. The return typically comes from things like perpetual funding rates rather than price direction. This is why the category is basis trading.
The yield from these positions flows to asUSDF, the yield-bearing form of USDF. Holders who want the yield take asUSDF, while USDF itself acts as the stable unit. The project does not give fee splits or the exact strategy design.

Pros and cons
What we like
- Clear design: USDT converts to USDF at a stated 1:1 ratio.
- Yield comes from delta-neutral positions rather than directional bets.
- About $113M TVL on DefiLlama suggests meaningful usage.
- Tied directly to a large perp DEX where it can be used as margin.
- Listed since late 2024, giving it a track record of more than a year.
Watch out for
- No audits are listed on DefiLlama for this product, so smart-contract assurance is not documented publicly.
- Yield depends on delta-neutral positions, which carry exposure to funding rates, venue risk and execution risk.
- The 1:1 USDT conversion is a stated design, but redemption terms, limits and delays are not public.
- Reserve composition, custody of the underlying USDT and any attestation details are not published publicly.
- USDF is tied to the Aster ecosystem, so problems at the exchange would likely affect the stablecoin.
- Fee and yield figures are not stated, so users cannot judge returns from public sources alone.
Aster USDF fees
Fees for minting, redeeming or staking USDF are not published publicly. The Aster homepage markets the platform as having low fees for trading, but gives no numbers.
Users should check the Aster app and docs for conversion terms, asUSDF yield rates and trading fees before depositing. Returns come from the strategy rather than from a fixed rate.
Is Aster USDF safe?
DefiLlama lists no audits for this product. The project does not describe reserve attestations, custody arrangements or redemption limits for the underlying USDT, so those should be checked in the Aster docs.
Delta-neutral strategies carry risks such as negative funding rates, liquidation of hedge positions, counterparty or venue failure and de-pegging under stress. USDF also depends on the Aster platform, so platform issues could affect it. Treat it as a DeFi product with real risk, not a bank deposit, and check local regulation for stablecoin and derivatives products.
