How it works
Fees
Trading
Every buy and every sell on a curve pays 1%, taken in USDT. The fee is split 40% to the token's creator and 60% to the protocol, and both parts accrue in the FeeVault contract.
| Share | Where it goes | |
|---|---|---|
| Creator | 0.4% of each trade | Accrues per creator in the FeeVault; claimable any time from the profile page. |
| Protocol | 0.6% of each trade | Accrues in the FeeVault; claimed to the treasury and used for buybacks of the official token, which are burned. |
Claiming creator fees
Fees never expire. Open your profile: it lists every token you created, what each has earned and the claimable total. One transaction pays it all in USDT.
On top of the trading fee
- Leveraged token fees: the vault charges a small streaming fee on its NAV and a redemption fee when LT is redeemed, both going to the treasury. They are already reflected in the exchange rate and in the sell quote.
- Funding: the perpetual position pays or receives funding on Aster; the keeper mirrors it on-chain so the vault bears its true cost. It shows up as a slow drift of the exchange rate.
- Paying in BNB: two PancakeSwap V2 legs (BNB → USDT on entry, USDT → BNB on exit) at 0.25% each, plus the pool's price impact for large amounts.
- Gas: BNB Chain transactions cost a few cents.
Official token
The AST token is not a curve token; its own contract applies about 1% on buys and sells. See Official token.
