More questions
07 / P2P SAFETY

Buying crypto on P2P?
Follow four rules.

Most P2P problems — from frozen bank accounts to payment disputes — start with funds of unknown origin. The right merchant, matching names and good records keep you safe.

Use a dedicated bank account

Keep a separate account just for P2P trades — not the one your salary, mortgage or bills run through — so any issue won't touch your everyday money.

Trade only with reputable merchants

Choose verified merchants with a long history, many completed orders and high completion and positive-feedback rates. Skip brand-new accounts and prices far from the market.

Make sure all names match

The payer, your OKX verified name and the receiving account holder must be the same person. Never accept third-party payments.

Keep your records

Save order screenshots, payment receipts and chat logs so you can explain where the funds came from if your bank asks.

08 / ACCOUNT SECURITY

Three security
settings to turn on.

Securing your account on day one takes minutes and greatly reduces the risk of phishing and account takeover.

01 / 2FA

Turn on Google Authenticator

Logins, withdrawals and security changes require a one-time code, so a leaked password alone isn't enough to take over your account.

02 / ANTI-PHISHING

Set an anti-phishing code

Once enabled, every genuine OKX email includes your personal code. If an “OKX” email doesn't have it, don't click anything.

03 / VERIFY

Verify through official channels

If someone claiming to be “OKX support” contacts you by DM, phone or group chat, check them on OKX's official verification page. Anyone asking for your codes or password is a scammer.

09 / QUESTIONS

OKX referral code
FAQ.

What is the OKX referral code?

The OKX referral code recommended on this site is OK66688. Enter it in the “Referral code” field when you sign up, or register through okx.com/join/OK66688 and it is filled in automatically.

Where do I enter the OKX referral code?

On the website, it's the “Referral code (optional)” box below the sign-up form. In the app, expand “Referral code” below the email / phone field on the sign-up screen. If you use the referral link it's filled in for you — just check that it shows OK66688.

I forgot to enter a referral code. Can I add it later?

Usually not. The referral is linked when the account is created and generally can't be added or changed afterwards, so check the code before you submit. For special cases, contact OKX support.

I already have an OKX account. Can I still get 20% off?

An existing account can't be re-linked to a new code. If your account isn't verified yet, you can register again with a different email or phone number and enter OK66688. If it is verified, withdraw all assets, close the old account in the app's account settings and register again in your own name. Whether you can re-verify is up to OKX's rules — never open an account with someone else's identity.

What do I get with referral code OK66688?

Registering with OK66688 gives you 20% off trading fees for life on both spot and futures, plus the new-user mystery box worth up to 60,000 USDT. Exact rates and rewards are shown on OKX's official pages.

How do I claim the mystery box (up to 60,000 USDT)?

There are two parts: after you sign up and verify your identity, open the sign-up mystery box in the OKX app's Rewards Center; after your first deposit (on-chain or P2P), open the deposit mystery box. Boxes contain BTC, ETH or fee vouchers — eligibility and caps are shown in the Rewards Center.

Is there an OKX promo code or bonus code?

OKX uses referral codes rather than separate promo codes. Enter OK66688 in the referral code field at sign-up to get the 20% fee discount and new-user rewards.

What's the difference between a referral code and a referral link?

They do the same thing. The referral code is typed in by hand; the referral link fills in the same code automatically. On this site both point to OK66688.

Is OKX the same as OKEx?

Yes. OKEx rebranded to OKX in 2022, so guides and codes for OKEx refer to the same exchange. Always register and download from the official okx.com domain.

Where can I download the official OKX app?

On iPhone, search OKX in the App Store. On Android, use Google Play or the OKX download page (okx.com/download). Never install APKs from unknown sources.

What do I need for identity verification (KYC)? Is it safe?

You need a valid government-issued ID (such as a passport, national ID or driver's license — accepted types are shown on the verification page) and a quick face scan. Submit documents only inside the official OKX app or website, and never send ID photos to anyone claiming to be support.

How do I buy crypto safely on P2P?

Follow four rules: use a dedicated bank account for P2P; trade only with verified merchants with many completed orders and high ratings; make sure the payer, your OKX verified name and the receiving account holder match, and refuse third-party payments; and keep order screenshots and chat logs so you can explain the source of funds if your bank asks.

Is OKX safe? Does it publish proof of reserves?

OKX publishes proof of reserves (PoR) every month, and you can check that your own assets are included using its Merkle tree tool. We also recommend turning on Google Authenticator and an anti-phishing code.

Is this the official OKX website?

No. This is an independent OKX referral guide. We don't offer logins, deposits or custody — all registration and trading happen on the official OKX platform at okx.com. We may earn a referral commission if you sign up through our links.
