XT.COM Referral Code FEEOTTER: 70% Fee Rebate (2026)

Fee Otter's XT.COM referral code is FEEOTTER, already built into our sign-up link. Register with it and you get 70% of your futures fees back (60% automatic from the exchange plus 10% extra from Fee Otter), about 3.5x a common 20% code; spot fees come back at 45% (checked October 2026). Full rates and evidence: referral codes and rebate rates by exchange.

The XT.COM referral code (invite code) is FEEOTTER, and it is built into our dedicated link.

Registering with it earns a futures fee rebate of 70%: a 60% automatic rebate from the exchange, plus 10% more once your UID is bound through Fee Otter. Most referral codes out there pay 20% (some 25%); 70% is 3.5 times a typical code. On 1,000 USDT of monthly fees, a typical 20% code returns 200 USDT; ours returns 700 USDT.

This page covers the code itself. Rates and worked examples are in the XT.COM fee rebate guide; the full account-opening walkthrough is in the XT.COM registration guide.

What is the XT.COM referral code?

The code is FEEOTTER. The button below uses a dedicated link that already carries it, so the "Referral code (optional)" field is filled in for you.

Referral code, invite code, referral ID: the same thing?

Yes. Some people say "referral code", others "invite code", and some interfaces say Referral ID; all of them mean the one field you fill in at signup. XT.COM's English signup page labels it "Referral code (optional)" and the Chinese page 「推薦碼（選填）」; the official XT.COM referral page runs on the same mechanism. Whatever it is called, the code that goes in that field is FEEOTTER.

Two other things get mixed up with it. A "referral link" is the same code built into a URL: signing up through it fills in our code automatically, with exactly the same effect as typing it. Your UID is your own account number, not a code; after signup it is the UID you bind on the rebate site; see what an exchange UID is and where to find it.

Where do you enter the code?

The XT.COM signup page ("Sign up" in the top right on the website; on the app, "Get started" on the home screen → "Sign up now") has a "Referral code (optional)" field on the same screen as the email or phone number. Entering through the link above fills it in automatically, with nothing to type; check it and submit.

Through the dedicated link the field arrives filled in and ticked, and the right-hand side is the signup page XT.COM set up for us, stating “60% Auto-Rebate from XT.COM”; that 60% is returned by XT.COM automatically (35% on spot):

We set the exchange-side automatic rebate to the highest the exchange allows. That layer is settled by the exchange automatically, without passing through Fee Otter.

App and web: step by step

XT.COM's app and website have different entry points, but the steps after that are the same. Six steps get you registered and earning rebates:

1. Open the dedicated signup link on this page; to register manually, click "Sign up" at the top right of the website, or in the app tap "Get started" → "Sign up now" on the home screen.
2. Enter an email address or phone number you use, and set a strong password.
3. On the same page, check that the "Referral code (optional)" field shows FEEOTTER; through the dedicated link it already is.
4. After submitting, enter the 6-digit code sent to your email or phone to open the account, then turn on two-factor authentication (2FA) straight away.
5. Find your UID: on the web, go to the personal centre → Overview, where the UID sits at the top of the page; in the app, tap the account centre icon at the top left.
6. On the Fee Otter rebate site, choose XT.COM, paste the UID and submit. Only the UID is needed: no API key, no password.

Step 3 is the only step that cannot be changed once submitted. For KYC and deposit details, see the XT.COM registration guide.

How do I check the code was applied?

If the code did not stick, you get no rebate. Check it this way:

1. At sign-up: before you submit, look at the referral code field and make sure it says FEEOTTER. Signing up through our link fills it in for you.
2. Bind your UID on Fee Otter: enter your XT.COM UID on the Fee Otter rebate site. After you submit it, we check XT.COM's referral list, the first time within about 5 minutes. If you are under our code, the status changes to "Verified" and we email you. If it still says "Pending review" after 5 hours, your UID is not on the list: check that you signed up with FEEOTTER, or contact support.

If you trade large volumes and want to confirm before your first trade, contact support and we will check it by hand. If the code did not stick, see the XT.COM rebinding guide for your options.

How much does it earn?

The futures rebate totals 70% (60% automatic from the exchange plus a 10% Fee Otter extra), 3.5 times a typical 20% code:

Using XT.COM futures rates (taker 0.06%, maker 0.04%) at 70% taker fills, the blended rate is 0.054%:

The gap is especially worth working out on XT.COM, because its 0.2% spot rate is high (the same as HTX) (official fee page), so the same percentage gap converts into more money. The 0.06% futures taker fee matches Bitget and HTX, and with the 70% rebate stacked you pay 0.018%. Full comparison in the XT.COM fee rebate guide.

How much more does Fee Otter pay than a typical 20% or 25% code?

The table shows the combined rebate when you bind through Fee Otter on futures (60% automatic plus a 10% extra), against the 20% and 25% codes commonly found online:

On 1,000 USDT of monthly futures fees, a typical 20% code returns 200 USDT and a 25% code 250 USDT; ours returns 700 USDT at 70%. Over a year that is 6,000 USDT more than a 20% code.

If you are already a VIP on an exchange and want to rebind or sign up on another exchange, contact support. We can help you apply for special trading benefits or a higher rebate rate.

Net rates make it clearer. XT.COM's futures taker fee is 0.06% (official fee page, verified 2026-09-24): a typical 20% code leaves you paying 0.048%, our code 0.018%. The 0.2% spot fee is double the 0.1% common elsewhere, so spot is still better placed on a lower-fee exchange.

The three ways people get this wrong

• Assuming it can be added later. An XT.COM referral code can only be entered at signup; once the account exists it cannot be added or changed. Miss it and rebinding is the only route.
• Clicking another referral link mid-signup. The later one overwrites the first. Pick your code and go through that one link end to end.
• Typing another exchange's code. The code is FEEOTTER; registering through the dedicated link rules this out.

Is the code still valid? Does it expire?

FEEOTTER is a long-term partnership code between Fee Otter and XT.COM, not a limited-time campaign code, and has no expiry date. Rebate percentages can change, but the binding itself does not lapse.

Already have an XT.COM account?

The code cannot be backfilled, but rebinding on XT.COM is the simplest of the switching paths we document: register again through the dedicated link with a phone number or email never used on XT.COM. No KYC is needed (fiat and P2P do require it, per the official guide), and unverified accounts can withdraw up to 200,000 USDT a day (per XT.COM's official Withdrawal Limit Guide). Steps in the XT.COM rebind guide.

FAQ

Are the XT.COM referral code and invite code the same thing?

Yes. Referral code, invite code and invitation code all mean the same field entered at signup, and XT.COM's code, FEEOTTER, is built into the dedicated link.

Does the code discount fees?

The rate you see when placing an order does not change; XT.COM charges first and refunds later: under Fee Otter's binding terms, 60% on futures (35% on spot) comes back automatically, and once your UID is bound through Fee Otter, a 10% extra is added on top, for 70% combined on futures and 45% on spot.

What happens if I skip the code?

The code can only be entered at signup and cannot be added afterwards, so register through our link: XT.COM returns 60% on futures automatically, and once your UID is bound the 10% extra takes it to 70%. Using our code does not cost you anything extra.

What do I do after using the code?

Bind your XT.COM UID on the Fee Otter rebate site. The code decides the first layer (60% on futures, 35% on spot); the second layer's extra rebate only starts accruing once your UID is bound.

XT.COM's spot fees are high. Is it still worth using?

For futures, yes: with the 70% rebate stacked, the effective rate is below Bitget, Binance and Bybit. For spot, XT.COM is not recommended: the 0.2% fee is double the other exchanges' 0.1%, and it stays more expensive after the rebate.

How much more does the XT.COM code pay than a typical code?

Bound through Fee Otter, futures pay 70%; on 1,000 USDT of monthly futures fees, a typical code returns 200 USDT and ours 700 USDT.

I already have an XT.COM account. Do I need KYC to rebind to Fee Otter?

No. Register again through the dedicated link with a phone number or email never used on XT.COM; the new account can trade, deposit and withdraw without KYC, which is only required for fiat and P2P. See the XT.COM rebind guide.
