USDF and asUSDF FAQs

USDF FAQ

What is USDF?

USDF is a yield-bearing stablecoin minted with USDT. USDT and USDF are fully convertible at a 1:1 ratio on Aster. The contract address is 0x5A110fC00474038f6c02E89C707D638602EA44B5.

What yield sources does USDF have?

Minting USDF earns you Au points. Au points grant an allocation of the $AST airdrop.

What happens to my USDT?

USDT funds are sent to Aster’s Ceffu account. Ceffu is Aster’s custodial partner. The funds are then used to create delta-neutral positions which back USDF and which generates asUSDF yields.

How is Au calculated?

This depends on your USDT investment. For example, if you stake 100 USDT, USDT price is $1 and USDF Au multiplier is 20x, your mint earns 100 x 20 = 2,000 Au.

Since USDT is a stablecoin, you will continue earning (100 x 20) Au per hour.

What is Smart Mint USDF?

Smart Mint USDF is a mechanism to optimize USDT to USDF rates so that you get the best conversion rate. Your mint will be executed via the Aster USDF mint contract, or via PancakeSwap.

Minting USDF with USDT on Aster adheres to a 1:1 ratio. However, USDF/USDT liquidity pools on PancakeSwap may see some price deviation—for example, minting on Aster could potentially result in a lower amount of USDF than if you had bought USDF on PancakeSwap. Smart Mint accounts for this.

What is the minting fee?

There is no minting fee if your mint is executed on Aster. For example, if Alice uses 1000 USDT to mint USDF, she will receive 1000 USDF.

There is a small fee if your mint is executed via PancakeSwap. Before swapping, you will be able to see the estimated fee.
