Aster USDF vs BitFi Basis: which yield product fits? (2026)

Aster USDF is a yield-bearing stablecoin built around the Aster perpetuals platform. USDT is used to create delta-neutral positions, and USDF is described as converting to and from USDT at a 1:1 ratio. Users stake into asUSDF to access yield. Its scope is relatively focused: it is listed on BNB Chain and is designed to work as margin in the wider Aster platform.

BitFi Basis has a broader product range and chain footprint. It offers bfUSD, a yield-bearing stablecoin with Pulsar and Horizon strategies, as well as bfBTC, a Bitcoin yield product. It is listed across seven networks, including Ethereum, BNB Chain and Base. BitFi says its strategy is about 90% delta-neutral and 10% tactical. In short, Aster centers on USDF within one trading ecosystem; BitFi caters to stablecoin and Bitcoin holders across more chains.

Aster describes USDF’s backing strategy and a 1:1 USDT conversion, but does not publish a yield rate. Its fees for minting, redeeming or staking are also not published. The conversion ratio alone does not establish the practical redemption terms: limits, timing and other conditions are not stated, so check those before depositing.

BitFi presents two bfUSD strategies: Pulsar for higher yield with moderate risk, and Horizon for stable yield with the lowest risk. Its homepage gives yield ranges, including 15–30% or more for stablecoins, but those are project figures and are not guaranteed. Management, performance and withdrawal fees are not published. Both products require you to weigh strategy returns against costs and terms that are not stated. Check the relevant app and documentation for current rates, fees, withdrawal conditions and network gas costs before committing funds.

Neither product has audits listed in the product details. BitFi says it has an audit report, so users should check the report directly and confirm which contracts and versions it covers. BitFi also names Ceffu as a custodian and says assets use institutional custody alongside smart contracts. That does not remove the counterparty and operational risks of off-chain trading, custody or exchange positions.

Aster’s reserve composition, underlying USDT custody, attestations and redemption limits are not published. Its delta-neutral positions can face negative funding rates, hedge liquidation, venue failure and execution problems. BitFi’s delta-neutral strategy can also lose money in extreme funding-rate or exchange-failure scenarios. Aster’s link to the Aster platform and BitFi’s off-chain activity create different dependencies; neither should be treated as a bank deposit or as risk-free. Only deposit funds you can afford to lose.

Choose Aster USDF if you want a BNB Chain stablecoin designed to connect directly to the Aster trading platform, and you are comfortable with its delta-neutral backing and the fact that reserve and redemption details are not published. Its stated 1:1 USDT conversion is a clear design point, but confirm the actual terms before using it.

Choose BitFi Basis if you value access across multiple chains or want a product for Bitcoin as well as stablecoins. Its two bfUSD strategies offer a stated choice of risk profiles, while bfBTC adds a different asset type. That wider choice comes with off-chain trading and custody exposure, and its headline yields are not guaranteed. Neither is an obvious choice for anyone who needs published fees and comprehensive public detail before depositing. Compare the specific withdrawal and custody terms that apply to the product you plan to use.
