Why most codes only give 5%
GMX uses a tiered referral system. The discount you get depends on the tier of the code you use. Anyone can create a Tier 1 code in seconds, but reaching higher tiers requires significant referred trading volume.
The code PRO is a verified Tier 3 referral code — the highest tier available — which guarantees the full 10% discount on all trading fees.
Both Tier 2 and Tier 3 give traders the same 10% discount. The difference is in the affiliate commission. Code PRO is Tier 3, confirming it meets the strictest requirements.

GMX vs centralized exchanges
Unlike Binance, Bybit, or OKX, GMX is a fully decentralized protocol. There is no company holding your funds, no KYC process, and no risk of exchange insolvency. You trade directly from your own wallet.
| Feature | GMX | Centralized exchanges |
|---|---|---|
| Custody | Self-custody (your wallet) | Exchange holds your funds |
| KYC required | No | Yes (mandatory) |
| Withdrawal limits | None | Tiered by verification |
| Pricing model | Oracle-based (Chainlink) | Orderbook |
| Max leverage | Up to 100x | Up to 125x |
| Available markets | 40+ pairs | 200+ pairs |
| Trading fees | 0.05% – 0.07% | 0.01% – 0.10% |
| Fee with referral code | 0.045% – 0.063% (PRO) | Varies by code |
GMX is ideal for traders who prioritize self-custody and privacy. The oracle-based pricing model also eliminates frontrunning and provides guaranteed execution without slippage on supported markets.

About GMX
GMX is a decentralized perpetual exchange that launched in 2021 on Arbitrum, later expanding to Avalanche. It allows traders to go long or short on crypto assets with up to 100x leverage — directly from their own wallets, with no account creation or KYC.
The protocol uses a unique multi-asset liquidity pool model (GM pools in V2) where liquidity providers earn fees from traders. Pricing is oracle-based via Chainlink, which eliminates frontrunning and provides zero-slippage execution on supported markets.
Since launch, GMX has processed over $200 billion in cumulative trading volume and consistently ranks among the top 5 decentralized perpetual exchanges by volume. The protocol is fully open-source and governed by GMX token holders.
GMX V2 introduced isolated pools for each trading pair, reducing risk for liquidity providers and enabling lower fees on many markets. New assets are added regularly based on community governance votes. The referral code PRO applies across all V2 markets on both Arbitrum and Avalanche.
