Aster Referral Code:
MMTz04

The referral code on this page is MMTz04. Under Aster's 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 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. To set the code, visit 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 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.

Not much per trade, and it is worth saying so plainly. Per Aster's fee documentation, 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.

How Does the Aster Referral Program Work?

According to Aster's official referral documentation, 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.

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 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 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. For a breakdown of every fee, see our fee guide, linked at the foot of this page.

The program covers Aster's markets, including crypto perps, high-leverage trading up to 1001x and spot. To see how Aster compares with other venues, read our Aster vs Hyperliquid comparison. The 5% figure applies to the fees you pay regardless of how often you trade.
