How this page makes money **Asterpedia earns a commission when you sign up to Aster through a link or code on this page.** Aster pays a referrer 10% of the trading fees a referred trader pays, and the referrer decides how much of that to hand back. Code **MMTz04** is set to an even split, so Aster returns 5% of the fees you pay to you as a rebate, credited after the fact rather than taken off at the point of trade. Aster runs the program and sets its terms. The commission is what pays for this site, and it does not decide which figures we publish. Our [methodology page](https://asterpedia.com/methodology) covers where the numbers come from and how they are checked. [Trade on Aster - 5% Fee Rebate](https://www.asterdex.com/en/referral/MMTz04) ## Aster Referral Code (2026) The referral code on this page is **MMTz04**. Under [Aster's referral program](https://docs.asterdex.com/program-and-rewards/referral-program) a referred user receives nothing by default. Aster pays the referrer a 10% commission on the referred user's trading fees, and the referrer decides whether to pass any of it back. This account is configured for a 5/5 split, so 5% of the fees you pay on Aster's [perp and spot markets](https://asterpedia.com/guides/fees/aster-fees-explained) comes back to you. That 5% arrives as a rebate rather than a discount. Aster calculates it daily at 00:00 UTC and credits it the following day, in whatever asset the fee was paid in, so the price you see at the moment of the trade is the undiscounted one. What the rebate is calculated against is [the full Aster fee schedule](https://asterpedia.com/guides/fees), which is worth reading first if you want to know what 5% of your fees is likely to come to. To set the code, visit [www.asterdex.com/en/referral/MMTz04](https://www.asterdex.com/en/referral/MMTz04) and sign up. The link carries the code, so there is nothing to type and nothing to activate. **Timing:** per Aster's documented program terms, the referral relationship is set when the account is created, and it runs for **365 days**. Aster documents the separate [5% reduction for paying fees in ASTER](https://asterpedia.com/ecosystem/what-is-the-aster-token) as applying independently of it. These are Aster's rules to set and to change, so check the program page before you act on anything here. ## What the Referral Code Gets You 5% Of your fees back as a rebate 365 days Referral relationship, per Aster docs At sign-up When Aster applies the code ## How Much Is the Aster Referral Rebate Actually Worth? Not much per trade, and it is worth saying so plainly. Per [Aster's fee documentation](https://docs.asterdex.com), perps run **0%** maker and around **0.04%** taker, and spot around 0.005% maker / 0.04% taker. Returning 5% of a 0.04% taker fee works out at roughly **0.002% of notional**, or about **$0.20 per $10,000** of taker volume, credited after the fact rather than shaved off the fee you pay. Aster documents the separate 5% reduction for paying fees in ASTER as applying independently. The case for setting the code is that it costs nothing and Aster applies it at sign-up, not that it will change your P&L. Check the current rates on Aster before trading, because they change.

Aster calculates the rebate daily at 00:00 UTC and credits it the next day in the asset the fee was paid in, with no promo code to enter.

Signing up through the link attaches code MMTz04 to the new account. ## How the Aster Referral Program Works ### How Does the Aster Referral Program Work? According to [Aster's official referral documentation](https://docs.asterdex.com/program-and-rewards/referral-program), Aster pays a default **10% commission** on a referred user's trading fees, and the referred user gets nothing unless the referrer chooses to pass part of it back. This site is configured for a 5/5 split, so half of that commission is credited to you as a **rebate worth 5% of the fees you pay** across Aster's perp and spot markets. The relationship is set when the account is created, and there is no promo code to re-enter per trade. Aster documents the pay-in-ASTER reduction as separate from it. ### How Long Does the Aster Referral Last? Per the same documentation, the referral relationship lasts **365 days** from sign-up. During that period Aster credits the rebate on fees you pay, calculated daily at 00:00 UTC and paid the next day in the asset the fee was charged in. Against a published schedule of 0% maker and around 0.04% taker on perps, and around 0.005% maker / 0.04% taker on spot, that is a small figure in absolute terms. Check the current rates before trading. ### How Do You Get an Aster Referral Code? Use the referral code **MMTz04** shown on this page. Click the referral link above to visit [www.asterdex.com/en/referral/MMTz04](https://www.asterdex.com/en/referral/MMTz04) and sign up, and Aster attaches the code to the new account. If you already trade on Aster and want your own code to share, open the Referrals section inside the [Aster app](https://www.asterdex.com/en/referral/MMTz04) to generate a personal link. Because the code is applied at account creation, share yours before your friends register. Centralized exchanges often let a promo code be entered at any time. Aster's documented program works differently: the referral relationship is set at account creation, and the link carries the code at that moment. If you have already registered without one, Aster is the party to ask about it, not us. The rebate is separate from the pay-in-ASTER reduction, which you enable by paying trading fees in $ASTER, and Aster documents the two as applying independently.

The program covers Aster's markets, including crypto perps, [high-leverage trading up to 1001x](https://asterpedia.com/guides/trading/aster-1001x-leverage-explained) and spot.
