What Fees Does Aster Charge?
Aster uses a maker-taker fee model with some of the lowest base rates in the perpetual futures market. On USDT-margined perps, makers pay 0% and takers pay 0.04% — a $10,000 taker trade costs just $4.00, and a maker trade is free. Spot trading is 0.005% maker / 0.04% taker. These rates can change as Aster updates its schedule, so always verify against the official docs and the app before trading.
Base Rate Summary
- USDT-margined perps: 0% maker / 0.04% taker
- Spot trading: 0.005% maker / 0.04% taker
- Pay fees in ASTER: 5% discount on perp and spot fees
- Referral (code MMTz04): additional 5% off, stackable
- 1001x mode: separate fee structure (see below)
Two Ways to Reduce Fees
- Pay fees in ASTER for a 5% discount (enabled with a toggle)
- Sign up with referral code MMTz04 for an additional 5% — applied at sign-up, can't be added later, lasts 365 days
Verify before you trade: Aster ships fast and fee schedules change. Always confirm the current perp, spot, and 1001x rates in the official Aster docs and in the app before sizing a position.
How Aster Fees Compare to Centralized Exchanges
Compared to major centralized exchanges, Aster's fee structure is highly competitive. Binance futures charge roughly 0.020% maker / 0.050% taker at the base tier, Bybit around 0.020% / 0.055%, and OKX around 0.020% / 0.050% — all higher than Aster's 0% maker / 0.04% taker on USDT perps. The structural advantage, however, is custody: Aster is a non-custodial DEX, so your funds stay in your own wallet and you can withdraw at any time without permission. For active traders executing dozens of trades daily, the cumulative savings from a 0% maker rate, a low 0.04% taker rate, and the stackable ASTER and referral discounts can add up to hundreds of dollars monthly.
| Exchange | Perp Maker | Perp Taker | Custody | KYC |
|---|---|---|---|---|
| Aster | 0% | 0.04% | Self-custody | None |
| Binance | 0.020% | 0.050% | Custodial | Required |
| Bybit | 0.020% | 0.055% | Custodial | Required |
| OKX | 0.020% | 0.050% | Custodial | Required |

Stacking the Two Aster Discounts
Aster keeps fee savings simple: there are two discounts and they stack. The first is the ASTER fee discount — toggle on "pay fees in ASTER" and you get 5% off perp and spot fees. The second is the referral discount — sign up with code MMTz04 and you get an additional 5% off your trading fees. The referral discount is applied at sign-up (it cannot be added to an existing account later) and lasts 365 days. Applied together, they meaningfully reduce an already-low base rate.
| Account Profile | Effective Taker Rate | Fee on $10K Trade | Saving vs Base |
|---|---|---|---|
| Base, no discounts | 0.0400% | $4.00 | — |
| Pay fees in ASTER (5% off) | 0.0380% | $3.80 | $0.20 (5%) |
| Referral code MMTz04 (5% off) | 0.0380% | $3.80 | $0.20 (5%) |
| Pay in ASTER + referral (stacked) | 0.0361% | $3.61 | $0.39 (≈9.75%) |
Maker trades on USDT-margined perps are free (0%), so the taker side is what these discounts reduce. Figures are illustrative — verify current rates against the official Aster docs and the app.
1001x Mode Fees
Aster's one-click 1001x mode uses a different structure from the order-book perps. Standard pairs charge roughly 0.08% to open and 0.08% to close on notional. At the highest leverage band (500x–1001x), there is no opening fee and a dynamic closing fee on realized PnL (with a minimum around 0.03%). A small network execution fee also applies — about $0.50 on BNB Chain or $0.20 on Arbitrum, since Simple mode runs through the ALP pool on those networks. Because these figures move quickly, confirm them in the app before opening a high-leverage position.
Spot Trading Costs
Aster spot trading (for example, the ASTERUSDT pair) is priced at 0.005% maker and 0.04% taker. As with perps, both the 5% pay-in-ASTER discount and the 5% referral discount with code MMTz04 apply and stack. Spot is order-book based, so resting maker orders earn the very low 0.005% rate while immediate fills pay the 0.04% taker rate. Always confirm the current spot schedule in the docs, as Aster periodically adjusts its fee tables.
Real-World Fee Examples
- $10K perp maker trade: $0 in fees (0% maker)
- $10K perp taker trade: $4.00 in fees (0.04%)
- $5K spot taker fill: $2.00 (0.04%)
- $10K taker with both discounts: ≈$3.61 after pay-in-ASTER + MMTz04
Over a month of active trading, the zero maker rate and stacked discounts add up — especially for makers, who pay nothing on USDT-margined perps. Factor in the 5% pay-in-ASTER discount and the 5% referral discount, and Aster becomes one of the most cost-efficient venues for high-frequency perpetual trading.
