GMX referral code for up to 10% off trading fees
Enter code PRO when you sign up on GMX and the discount is applied automatically to your fees on every leverage trade. 10% off is the maximum any code can give — no deposit, no KYC, traded straight from your wallet.
Beware of fake GMX codes. Many sites push invalid or expired codes — PRO is a verified, working code. And 10% is the maximum any GMX code can save a trader, so ignore any code that claims more.

What the referral code gets you
A GMX referral code — also called a GMX promo code or discount code — is purely upside for the trader: it lowers the fees you pay and costs you nothing to use.
The full 10% off trading fees
Code PRO applies the maximum discount on opening and closing fees for every leverage position. 10% is the most any GMX code can give a trader — standard codes only give 5%.
Applied automatically
Once the code is registered to your account it works on all future trades. The discount is deducted from the position fee at execution — nothing to claim.
Your keys, your funds
GMX never takes custody. You trade directly from your own wallet, so the referral code changes your fees — never your control of your assets.
Stacks with deep liquidity
Lower fees on top of low slippage. GMX's pooled liquidity model is built for size, so the saving lands on trades that actually move.
How the 10% discount works
GMX is a decentralized perpetual exchange where you trade with leverage directly from your wallet. Its referral program rewards new traders with a fee discount that scales by the code's tier — and 10% is the protocol ceiling, so no valid code can ever give a trader more.
Code PRO applies the full 10% — the maximum. The discount comes off your opening and closing fees automatically; it doesn't apply to borrow or funding fees, which are separate.

Frequently asked questions
What is the GMX referral code?
It's a short code — PRO — that you register on GMX so a fee discount is applied to your leverage trades. It's free to use and is the standard way GMX rewards new traders.
How much do I save with the code?
Code PRO gives you the full 10% off opening and closing fees — and 10% is the maximum any GMX referral code can give a trader. Standard (Tier 1) codes only give 5%. The discount is deducted automatically from the position fee at execution.
Are there fake GMX referral codes?
Yes — a lot of sites advertise invalid, expired, or made-up codes, and some claim discounts of 15% or 20% that simply aren't possible. 10% is the protocol maximum for a trader, so treat any higher number as a red flag. PRO is a verified, working code that applies the full 10% discount.
Where do I enter the code on GMX?
Open the GMX app, connect your wallet, and go to the Referrals tab. Under the Traders section there's a field to enter a referral code. You only register it once.
Is using a referral code safe?
Yes. A referral code only changes the fees you pay — it never gives anyone access to your wallet or funds. GMX is non-custodial, so you keep control of your assets at all times.
Do I need to KYC or deposit to use the code?
No. GMX is permissionless: you connect a wallet and trade directly from it. There's no sign-up, no identity check and no deposit to a third party.
Which fees does the discount apply to?
The discount applies to opening and closing fees on leverage positions. It does not apply to borrow fees or funding fees, which are separate.

GMX fees explained
Trading perpetual futures on a decentralized exchange like GMX carries a different fee structure than most traders expect coming from centralized platforms. There is no order book, no maker or taker distinction, and no account-funding step. What you pay instead is a set of clearly defined costs: a position fee when you open or close a trade, a borrow fee that accrues while you hold the position open, and a funding fee that flows between the long and short side based on market imbalance.
