What Is an Exchange UID? How to Find and Bind It for Fee Rebates

You have opened your exchange account and you want a rebate platform to hand back part of your trading fees. The first thing you are usually asked for is not your login, not an API key, but a string of digits — your UID. Many people get stuck right here: they are not sure what a UID is, where to find it, or whether handing it over is safe. This guide explains, in plain language, exactly what a UID is and walks you through binding your UID and starting to earn rebates on our fee-rebate data platform (Quant Nova).

What is an exchange UID?

A UID (User Identifier) is the unique numeric account ID that an exchange assigns to you automatically the moment you register. It is different from your login email, phone number or nickname: an email can be changed and a nickname can be swapped, but your UID stays fixed from sign-up to account closure. It is how the exchange recognizes you as one specific, non-duplicated identity in its system.

Think of a UID like a bank account number. Someone who knows your account number can send money to you, but they cannot use that number to withdraw your funds. A UID works the same way: it is simply a publicly visible identity number that carries no password and no withdrawal permission, so a UID string alone can never move your assets. Getting this clear first avoids any misunderstanding when we talk about binding safety later.

How is a UID different from an API key or your password?

• UID: a read-only identity number used to recognize who you are; sharing it does not hand over control of your assets.
• Account password: your login credential, equivalent to your house key, which should never be given to any person or platform.
• API key: an authorization key for programmatic trading and queries, with permissions that can be broad; it is never needed for rebate binding, so anyone asking for an API key to "set up rebates" is a red flag.

Why does binding your UID let you earn rebates?

To attract new users, exchanges run referral/affiliate programs: when a user registers through a referral code, or later binds their UID under a referrer, the exchange returns part of that user's trading fees to the referrer. What a rebate platform does is pass that reward — which would otherwise be pocketed by the exchange or a large KOL — proportionally back to you, the person actually trading.

The key point is that the exchange uses your UID to decide whose referral relationship a batch of fees belongs to. So the core of binding is having the platform register your UID as its referral in the exchange back office. From then on, every fee your trades generate can be matched to your UID, and the rebate is calculated back to you. Without a correctly bound UID, the exchange simply has no way to know who to pay the rebate to.

This is why the invite code and the UID work as a pair: the invite code decides which referrer you belong to (our code for each exchange is listed below), and the UID decides who you are. Only when the two line up does the rebate chain hold.

Binding your UID and starting rebates on Quant Nova (our exclusive flow)

Most KOLs out there give you nothing but an invite code, and after you bind you cannot see how much you were actually rebated — that is the biggest information gap. Our fee-rebate data platform (Quant Nova) is a one-stop rebate data hub: once your UID is bound, you can review every single rebate line by line, your current balance, your rebate tier and your XP progress in the dashboard, and request a withdrawal directly. The whole flow is usually three steps:

1. Register or rebind with our invite code: a brand-new sign-up simply enters the invite code; if you already have an old account, follow that exchange's rebind flow (links below) to move the referral relationship over to us.
2. Enter your UID on the platform: log in to Quant Nova and paste the UID you found on the exchange into the binding field. Remember, only the UID is needed — never provide your password or API key.
3. Wait for verification: the system checks the exchange referral back office to confirm this UID really sits under us. Once it passes, binding takes effect, and your subsequent trading fees start counting toward your rebates and XP.

That verification step matters: it makes sure the UID you entered matches the actual referral relationship in the exchange back office, so you do not think you are bound while your fees quietly fail to count. This is exactly what grabbing a random KOL invite code cannot give you — you have no way to verify, you can only take it on trust.

Where to find your UID on each exchange

All five major exchanges keep the UID on the account information page, though the exact spot differs. Here is one short section for each, with the matching rebind guide; if you already have an old account and want to move your referral over, just open that exchange's rebind page and follow it.

Binance

After logging in, click your avatar or account in the top-left corner; the "UID" number shows at the top of your profile page, and the icon beside it copies it. On the app, it also appears under your nickname on the "Profile" page. The Binance invite code is NOVA888, with up to 40% (20% automatic from the exchange plus up to 20% more by rebate tier). See the full steps in the Binance rebind guide.

OKX

On both web and app, tap your avatar in the top-right corner and open the "Account" page to see your UID; click to copy. The OKX invite code is NOVA888, with a 20% rebate; for higher additional-reward arrangements, please contact support. See the OKX rebind guide.

Bitget

After logging in, open "Account" or your profile center; the UID shows next to your avatar. The Bitget invite code is NOVA888, with up to 50% (20% automatic from the exchange plus up to 30% more by rebate tier). See the Bitget rebind guide.

Bybit

Tap your avatar in the top-right corner to open the account overview; the UID sits under your nickname. Note carefully: Bybit's rebate is not a "20% + extra" stacked model but a single combined total of up to 40%, calculated differently from the other exchanges, so do not apply the others' logic to it. See the Bybit rebind guide.

Gate

After logging in, you can find the UID on the account information page (Gate sometimes labels it "User ID"). The Gate invite code is QUANTXXX (note it differs from the others), with up to 70% (20% automatic from the exchange plus up to 50% more by rebate tier). See the Gate rebind guide.

After binding your UID, how is your rebate tier calculated?

Binding your UID is only the start; how much you actually get back depends on your rebate tier. We use an experience-point (XP) system, and it works on a rolling 30-day basis, not a monthly settlement:

• XP = the trading fees (in USDT) you have accumulated over the past 30 days.
• The system recalculates daily on a rolling basis: today's XP is the sum of fees within the window of the past 30 days counting back from today.
• When your XP reaches a tier threshold, the new tier's rebate rate takes effect that same day — no waiting for a monthly close, and no "next month" delay.
• Conversely, if a stretch of high-fee days rolls out of the 30-day window and your XP drops below a threshold, your tier steps down accordingly.

Tier thresholds (XP = past-30-day fees in USDT): Lv.2 is 100, Lv.3 is 500, Lv.4 is 1000, Lv.5 is 2500 and SVIP is 5000; the top "Supernova" tier cannot be reached through XP and is granted separately by an administrator. The actual rebate percentage for each tier is authoritative as shown live in the table below:

Here is a worked XP example: suppose over the past 30 days you paid 600 USDT in fees on an exchange, so your XP is 600, already past Lv.3's threshold of 500 — from that day your rebate is calculated at the Lv.3 rate. If you then trade less and one day only 480 USDT remains inside the window, your XP falls below 500 and the system moves you back to Lv.2. The whole process recalculates automatically every day, and both upgrades and downgrades are reflected in real time.

Before binding your UID, look closely at the fee-versus-rebate gap

The real point of binding your UID is to claw back part of the fees you were going to pay anyway. So before choosing which exchange to bind, look closely at each one's raw fee rates and the real rebate gap after binding. See the fee-and-rebate comparison in the table below:

By the way, a KOL invite code usually gives a fixed discount of around 20% — bind it and that is the number you get. We add on top of that by rebate tier, so active traders reach a noticeably higher rate. For a fuller comparison of each exchange's program, see our crypto exchange fee rebate comparison; to understand the whole picture of rebates from the ground up, start with the pillar guide, the complete guide to crypto exchange fee rebates.

Worth noting: our team keeps real trading capital at every exchange and verifies the order and rebate chain with real money — we are not a hollow traffic-funnel shell, which is what lets us reconcile rebate data line by line.

Common mistakes and cautions when binding a UID

• Entering the wrong UID: one digit too many or too few fails verification, so always use the exchange's one-click copy rather than typing it by hand.
• Binding someone else's UID: the UID must belong to your own account; binding another person's routes the rebate to them.
• Handing over a password or API key by mistake: rebate binding only ever needs the UID; be wary of anyone asking for your password, API key or verification code.
• Entering the UID before rebinding an old account: if your account already sits under another referrer, you usually have to complete the rebind flow first (see each exchange's link above) before binding takes effect.

Frequently Asked Questions

Is there any asset risk in sharing my UID?

No. A UID is only a read-only identity number with no password and no withdrawal or trading permission, so no one can touch your assets with a UID string alone. What you really need to protect are your password, API key and two-factor codes — none of which are needed for rebate binding, only the UID.

How long does rebinding a UID take to take effect?

Plain UID binding verifies quickly and takes effect once the system confirms it in the exchange referral back office. When it involves rebinding away from a previous referrer, processing times vary by exchange — some are instant, others take several days up to a binding cycle. The actual timing follows each exchange's rules and platform announcements; see the relevant rebind guide.

Can one UID be bound to several rebate platforms at once?

No. An exchange back office recognizes only one referral relationship per UID at a time, so once it is bound under us it cannot simultaneously count for someone else. That is why you should confirm your current referral attribution and rebind first if needed.

After binding, how do I confirm the rebates are actually coming in?

Log in to the Quant Nova dashboard and you can see, line by line, the rebate matched to each trade, your current balance, your tier and your XP progress, and request a withdrawal directly. This "see every single line" transparency is exactly what a KOL who only hands over an invite code cannot offer.

Is my rebate tier recalculated monthly?

No. Tiers run on an experience-point (XP) system, where XP equals your accumulated trading fees over the past 30 days and the system recalculates daily on a rolling basis; the moment you hit a threshold the new tier's rate takes effect — it is not a monthly settlement and not a next-month upgrade.

I already registered with someone else's invite code — can I still move over?

In most cases yes: use each exchange's rebind flow to move the referral relationship under us. The corresponding steps are in the Binance, OKX, Bitget, Bybit and Gate rebind-guide links above.
