FEES & SAVINGS

Where to Read About Aster Fees

The short answers are below, then the guides that go further. What you pay on Aster depends on which surface you trade and which discounts you have switched on, and each of those has its own page.

Maintained by Asterpedia, active Aster trader

Four separate questions get filed under “Aster fees” and they have different answers. What the venue charges per trade is one. What the pay-in-ASTER discount and the referral rebate take off is another. High-leverage Simple mode runs on a pricing model that shares almost nothing with the order book. And where the collected fees end up — the buyback — is a token question rather than a trading one. Pick the one you came for.

THE FULL SCHEDULE

Aster Fees Explained: Perps, Spot, 1001x & ASTER Discounts

The rate card and the reasoning behind it — maker and taker on USDT- and USD1-margined perps, order-book spot, the 1001x model, and worked examples of what a given trade actually costs. Start here if you want a number.

SAVING ONE

Staking ASTER & the Pay-in-ASTER Discount

Holding and staking the token changes what you pay. How veASTER works, what the pay-in-ASTER toggle takes off, and how the two interact.

SAVING TWO

The Referral Rebate (Code MMTz04)

A second saving that stacks with the first, paid by Aster as a rebate on fees you have already paid rather than taken off at the point of trade. Per Aster’s documented program terms the code is applied at sign-up and the relationship runs for 365 days, so the ordering matters.

A DIFFERENT MODEL

1001x Mode & How It Is Priced

Simple mode is not the order book with a bigger number, and it is not priced like it either. Open and close fees on notional, the extreme-leverage tier, and the network execution fee.

WHERE THE FEES GO

Fee Buyback & Burn Tokenomics

The other half of the question: what Aster does with the fees it collects, and what the buyback means for ASTER supply.

AGAINST OTHER VENUES

Perp DEX Fee Index

What a position costs to open and close on Aster, Hyperliquid, dYdX and GMX, computed from each venue’s published rates rather than quoted off one side of a rate card.

Short answers

What does Aster charge to trade?

Two base rates cover almost everything on the venue. Per Aster's published fee documentation, USDT-margined perpetual futures charge 0% maker and 0.04% taker on notional. A resting limit order that adds liquidity costs nothing. A market order that crosses the spread on a $10,000 position costs $4. Order-book spot is 0.005% maker and 0.04% taker. Rates are set per product type, not per market, so no individual perp is cheaper than another. What you can actually change is whether you rest an order or take the other side of one.

How often is funding charged on Aster?

Every eight hours, so three settlements a day. Funding is not a fee Aster collects: it moves between the long and short sides of a perpetual to hold the contract near its index price, and depending on which way the rate sits you either pay it or are paid it. That also changes the arithmetic people get wrong when comparing venues. Annualize an Aster funding rate by multiplying by three and then by 365, not by 24 and 365, which is what a venue on hourly funding would give you. Live per-market rates are read from Aster's public futures API and shown, timestamped, on the Aster markets page.

How much does the referral code save?

Nothing on the trade ticket itself. Per Aster's documented referral program, the referrer earns a 10% commission on a referred trader's fees and decides how much of it to pass back. Code MMTz04 runs a 5/5 split, so 5% of the fees you pay comes back as a rebate. Aster calculates it daily at 00:00 UTC and credits it the following day in whatever asset the fee was paid in. The pay-in-ASTER discount is the other one, and that one does work at the point of trade, taking 5% off the fee itself. Both apply together, because the rebate is calculated on what you actually paid after the discount.

That is the whole answer for a single trade on Aster. Two things sit outside it. The full rate card, including USD1-margined perps, the 1001x model and worked cost examples, is on the Aster fee schedule, explained. And if the real question is whether Aster is cheap compared with somewhere else, a maker rate on its own will not tell you: the all-in perp DEX fee comparison computes what a round trip costs on Aster, Hyperliquid, dYdX and GMX from each venue's own published rates.

Before you size a position: Aster revises its fee schedule regularly, so treat every figure on this site as a dated snapshot and confirm the live numbers in the official Aster documentation and in the app.

Set the Code Before You Register

Per Aster's documented program terms the referral code is applied at sign-up. Aster runs the program and sets its rules, not this site. If you have not registered yet, deal with that part before you read the rest.

How these figures were verified

Aster revises its fee schedules, leverage caps and token mechanics regularly, so every figure here is a dated snapshot rather than a live feed. Where a number comes from Asterpedia’s own tracking rather than the documentation, it is labelled as such above.
