OKX mystery box:
what's inside and how to unlock it.

What's inside the OKX mystery box? Usually a voucher, not cash

Whether you searched “OKX mystery box”, “okx mistery box” or “OKX new user bonus”, it is the same thing. OKX's current terms don't use the words “mystery box”; they call it the New User Bonus. Rewards land in your account and you open each one in the app, so most people simply call it a mystery box. According to the OKX New User Bonus terms (updated 16 September 2026), each reward “might include crypto or rebate cards”.

The second half of that sentence matters. A rebate card is not money you can take out straight away. OKX describes rebate cards as rewards used as cashback on part or all of your trading fees (OKX ZERO Trading Fees FAQ, updated 26 August 2026). You only get value from one by trading before it expires.

Of the reward types OKX names in its current new user terms, only one is plain crypto. The rest are cards, vouchers, bonuses or passes. So read any “win up to” headline you see elsewhere as the top prize of a draw, not as a promise, and don't deposit more than you planned just to chase it.

Why didn't your OKX mystery box show up? Check these in order

1. The 48 hours aren't up yet. OKX says task confirmation and reward crediting can take up to 48 hours, so a reward that hasn't appeared yet may simply be on its way.
2. The account wasn't opened through a designated link. OKX's terms describe the New User Bonus as a program for new users signing up through referral, affiliate or other designated links. In Australia, accounts created outside those channels aren't eligible even if every task is done.
3. The deposit didn't count. Internal transfers between OKX accounts, red packets, rewards and P2P shared-order purchases don't count toward deposit tasks.
4. The trade didn't count. A trading task needs one single trade of the required size. Several smaller trades added together don't count, and zero-fee stablecoin pairs such as USDC/USDT and zero-fee Convert are excluded.
5. The task window closed. Every task has its own validity period, and the deadline is in the task details.
6. It expired before you opened it. A reward not opened within 30 days of arriving expires, and 180 days after sign-up the tasks and rewards are no longer visible at all.
7. The account or region isn't eligible. Rewards and tasks differ by country of residence. Sub-accounts can't take part, and accounts flagged in anti-fraud checks or opened as duplicates lose eligibility.

What should you do if the reward still isn't there?

Take a screenshot of the task page and your deposit or trade record, note when you finished, and wait the full 48 hours. Then open live chat from the OKX app and send both. That is the process OKX itself describes in its New User Bonus FAQ. If your problem is logging in or verification rather than the reward, see account restricted, login and verification fixes.

OKX new user tasks: how to unlock the mystery box after sign-up

The exact task list depends on where you live and which offer your account gets, so trust the Campaign center over any list online, this one included. Doing them in this order avoids the reasons for a missing reward listed above.

1. Sign up through the invite link. Click a button on this page and the sign-up page opens with OK66688 applied, nothing to type. If you register inside the OKX app yourself, type OK66688 into the referral code field before you submit.
2. Verify your identity on day one. OKX says you can trade, deposit and withdraw after completing identity verification, and it reviews applications within 24 hours (OKX help). In the app: Menu → Account settings → Identity verification.
3. Read your tasks in the Campaign center. In the app: Menu → Earn and rewards → Campaign center. On the web: More → Campaign center. Each task shows how long you have left.
4. Do the deposit task the way it counts. Buy crypto or deposit from another wallet or exchange. A transfer from a friend's OKX account or a red packet won't count.
5. Do the trading task as one trade. Place a single trade that meets the amount shown, on a pair that charges a fee. If a task asks for futures volume, remember that futures can wipe out your margin, and skipping one task is always an option.
6. Open the reward in the app within 30 days. Then check its lock-up and expiry dates under My rewards.

Where is the mystery box in the OKX app, and how long does it last?

• 30 days: how long you have to open each reward after it arrives. OKX's terms say rewards are opened through the OKX app.
• Task validity period: set per task and shown in the task details.
• Lock-up: rewards are locked on arrival and released automatically when the lock-up ends.
• 180 days after sign-up: the new user tasks and rewards can no longer be viewed.
• Voucher deadlines: tradeback vouchers carry their own activation and use dates, which OKX says can't be extended.

OKX can end the program or change its terms at any time without notice, so the dates in your own account are the ones that count (OKX New User Bonus terms).

What can you actually do with a rebate card, voucher or trading bonus?

How does an OKX rebate card pay you back?

A rebate card pays back trading fees on eligible products until its value is used up or it expires. Its value and expiry date are shown once it's credited. It suits people who were going to trade anyway; it is a poor reason to start trading.

How do you activate an OKX tradeback voucher?

You activate these under Reward center → My rewards → Tradeback voucher. According to the OKX Tradeback voucher FAQ (updated 14 August 2026), you can have only one activated voucher at a time: activating a new one switches the old one off for good, and the activation and use deadlines can't be extended.

Should a beginner use a trading bonus or contract voucher?

OKX's New User Full Rebate Program page (updated 26 August 2026) lists a trading bonus usable for derivatives and a contract voucher for one perpetual futures trade. Futures use leverage and can be liquidated quickly, so if you have never traded them, a spot trade or Simple Earn on USDT is a calmer first step.

What else is in the OKX new user bonus besides the box?

“OKX welcome bonus” and “OKX new user bonus” are the same idea under different names. Depending on your region, the app calls it New User Bonus or Welcome Rewards, and some regions add a separate rebate campaign.

The Full Rebate campaign runs for 29 days from registration by default, and any day's reward you don't claim in time is gone. For an overview of everything a new account gets, see the OKX sign up bonus guide.

Can you get the OKX mystery box in the UK?

Not through this site. Since 8 October 2023, the Financial Conduct Authority's rules apply to anyone marketing crypto to UK consumers: promotions need prominent risk warnings, first-time investors get a cooling-off period, and “refer a friend” bonuses are banned (FCA press release, 8 June 2023). The FCA's policy statement PS23/6 (June 2023) extends its ban on incentives to invest to crypto promotions. An invite link with a sign-up reward is exactly that kind of incentive, so this page doesn't offer UK residents a sign-up link or reward, and if your browser is set to UK time the sign-up buttons here are hidden.

If you already use OKX in the UK, the app shows what is available to your account. OKX's referral terms say rewards can be withheld for false identity information, so registering with a foreign address is no shortcut, and it isn't something this site will help with.

Why the sign-up link matters for the mystery box

OKX's terms describe the New User Bonus as a program for new users signing up through referral, affiliate or other designated links, and the OKX Referral Program FAQ (updated 5 October 2026) says people who join through a referral automatically join the New User Bonus Program. The same FAQ says the referral code can't be added or changed after the account is created, so it has to be right the first time.

The sign-up page opened by the button shows a 20% trading fee discount (checked 2026-10-16). New user rewards are separate and follow the campaign shown in your account, so check the Campaign center rather than any amount quoted online.
