Can You Add an Aster DEX Referral Code After Signing Up?
Many users wonder if they can add an Aster DEX referral code after creating their account. Here is everything you need to know about Aster DEX referral codes, when you can use them, and what to do if you missed entering one during registration.
Short Answer: No
Aster DEX referral codes can ONLY be entered during the initial account registration. Once your account is created, there is no option to add, change, or apply a referral code retroactively. This is a permanent system design choice by Aster DEX to prevent referral abuse.

Anti-Fraud & Abuse Prevention
If users could add referral codes after registration, it would enable widespread abuse. People could create accounts, trade for a while, and then retroactively assign referrals to generate fake commissions. Aster DEX locks the referral at signup to prevent this type of fraud.
Commission Tracking Integrity
Aster DEX needs to accurately track which referrer brought each new user to the platform. By locking the referral code at registration, Aster DEX ensures a clean, tamper-proof attribution trail for commission calculations and affiliate partner payouts.
