The OKX referral code is SAVE20. Create your account through OKX’s official partner campaign page, my.okx.com/en-eu/campaigns/save-20, and the code connects at registration with a 20% discount on eligible trading fees. That figure is not our marketing: it is the headline on OKX’s own campaign page, which we retrieved on 20 August 2026. This guide prints the confirmation, the fee math, the campaign terms that actually bind you, and the licence status of OKX’s EU entity.

Most code pages ask you to trust a banner. This one you can check in ten seconds. OKX’s partner campaign page states: «Use OKX referral code SAVE20 when creating your account and save 20% on eligible trading fees», and instructs: «Register through this official partner page to ensure the referral code is correctly connected to your new account» (OKX SAVE20 campaign page, retrieved 20 August 2026). When the operator’s own page states the number, you do not need to take any affiliate’s word for it, including ours.

OKX’s standard spot tier charges 0.08% maker and 0.10% taker. With the 20% discount the effective rates land at 0.064% maker and 0.08% taker:

The standard futures tier charges 0.02% maker and 0.05% taker. With the discount those become 0.016% and 0.04%. On $100,000 of monthly futures taker volume, that is $10 saved, every month, for as long as you trade.

The 20% applies to eligible trading fees as defined in the campaign terms. It does not reduce blockchain withdrawal fees, spreads, or funding payments on perpetuals. Volume-based VIP tiers price separately, and the campaign terms govern how the discount interacts with them.

The campaign terms restrict participation to your main account. Sub-account activity does not count toward the campaign, so do your qualifying trading from the main account.

OKX’s terms state that each user participates in one campaign at a time, and that the most recent registration wins. If you plan to join a deposit campaign later, read its terms before stacking assumptions.

Users from the countries listed in OKX’s risk and compliance disclosure cannot participate. The registration flow enforces this; if your country is eligible for OKX, the code path works.

Yes, and you can verify it at the source. The interim MiCA register that ESMA publishes listed OKX Europe Limited, commercial name OKX, as an authorised crypto-asset service provider with the Malta Financial Services Authority (MFSA) as competent authority, authorisation notification date 27 January 2025, and no end date, when we checked the register file on 20 August 2026. Download the CASP register from ESMA’s MiCA page and search for OKX Europe Limited to confirm it yourself. Our MiCA exchange comparison ranks the EU-regulated venues side by side.

SAVE20. Register through my.okx.com/en-eu/campaigns/save-20 and the code connects to your account with the 20% fee discount.

No. OKX documents the invitee discount range as 0 to 20%, and SAVE20 is configured at the maximum. A page advertising more contradicts OKX’s own rules.

The code’s documented benefit is the fee discount. New-user rewards run as separate rotating campaigns in the Rewards Hub, typically task-based rewards in the tens to low hundreds of USDT; the signup screen shows what runs in your region today.

No. The referral connects at account creation, which is why OKX tells you to register through the partner page rather than typing the code in later.

Any country where OKX accepts new users, minus the exclusions in OKX’s risk and compliance disclosure. EEA users are served by the MiCA-licensed OKX Europe Limited.

After registration, the fee schedule in your account shows the discounted rates, and the campaign appears under your Rewards Hub participation. If it does not, contact OKX support before you trade size.

Crypto prices are volatile and you can lose what you invest; leveraged futures can liquidate positions quickly. A fee discount does not change market risk. We may earn a commission when you register through the links on this page, and using the code does not increase your costs. The 20% figure and campaign terms were retrieved from OKX’s own campaign page, and the licence entry from ESMA’s register file, on 20 August 2026; both can change. Update log: 20 August 2026: rebuilt this guide around OKX’s official SAVE20 campaign page, added the ESMA licence verification, the fee charts and the claim steps.
