Crypto Exchange Referral Codes: What You Save, What's Required
Every code on this page has been tested through a real registration — we created an account, entered the code, and confirmed that the advertised discount activates. Codes are re-checked monthly.
Important: referral codes can only be entered during account creation. Most exchanges do not allow adding a code after registration is complete. If you skip this step, the fee discount is lost permanently for that account.
If your priority is the lowest trading fees, look at MEXC (0% maker fees + additional referral discount) and OKX (low base fees + 20% off with code). If you want the largest welcome bonus in real USDT, Bybit and BingX currently offer the highest verified amounts. If you have already chosen an exchange based on our reviews, simply find it below and copy the code before signing up.
What a Referral Code Actually Does
A referral code is an alphanumeric identifier that you enter during registration on a crypto exchange. It links your new account to a specific referral partner — in this case, Promokoin. The exchange uses this link to track where the new user came from.
Here is how it works on the exchange's side: every platform has a referral program that splits a portion of trading fees between the exchange, the referrer, and the new user. When you register with a code, the exchange gives you a discount on fees or a welcome bonus — and shares part of its revenue with the referrer. You pay nothing extra. In fact, registering with a referral code is always cheaper than registering without one, because the fee discount only activates through the code.
Referral codes are entered once — during account creation. Most exchanges do not allow adding or changing a code after registration is complete. If you skip this step, the discount is lost permanently for that account.
Each code on this page links to a detailed breakdown where we explain exactly what you receive and what conditions apply.
Where These Codes Come From
Every code on this page is issued directly by the exchange through its official referral program. Promokoin is registered as a partner with each platform listed here — these are not codes found on forums or copied from other websites.
Here is how it works: each exchange sets a total referral fee allocation — the percentage of trading fees that gets redistributed when a new user registers through a partner's code. This allocation is split between the new user and the referring partner. For example, if an exchange allocates a 40% fee benefit to a referral partnership, half of that — 20% — goes to you as a direct fee discount on every trade. The other half supports the maintenance and development of this project. The exact split varies by exchange, but in every case we configure the code to pass the maximum available discount to the user.
Most people visiting this page are registering on a crypto exchange for the first time. Without a referral code, a new account starts with standard fees and no welcome benefits — the exchange's referral budget simply goes unallocated. With a code, every trade costs less from the first transaction, and bonus tasks provide additional value during the early period when most users are still learning the platform and trading in small amounts.
A referral code never adds any cost to your account. Our goal is to make sure this information reaches new users before they create their accounts — because on most exchanges, the opportunity closes the moment registration is complete.
How We Verify These Codes
Listing a code is not enough — we need to confirm it delivers exactly what we describe.
We register a real account on the exchange using the code and open the account's fee schedule to verify that the discount percentage matches the rate we publish. If we state 20% off spot fees — we confirm that 20% appears in the fee settings, not 15%, not 10%. We check that welcome bonus tasks are accessible and that their conditions — deposit thresholds, trading volume requirements, expiration periods — match what we have documented. We record the results with screenshots of the applied discount and available reward tasks.
Every code is re-checked monthly. If an exchange updates its referral terms — changes the fee allocation, adjusts bonus amounts, or modifies task requirements — we update the listing to reflect current conditions. Each individual code page displays the date of the last verification so you can see how recent our check was.
If you register with a code from this page and the benefits do not match what we describe, report it through our Contact page. We investigate all reports and correct confirmed discrepancies within 48 hours.
Types of Referral Benefits — What's Real and What's Marketing
Exchange referral programs typically advertise large headline numbers — "$30,000 in bonuses" or "$10,000 USDT rewards." These numbers are technically accurate but almost never mean you receive that amount as cash. Understanding the difference between bonus types helps you set realistic expectations.
Fee discounts are the most valuable benefit for active traders. A 20% fee discount means you pay 20% less on every trade for the lifetime of your account. This is real, permanent savings that applies automatically. On a standard 0.10% spot fee, a 20% discount saves you $2 on every $10,000 traded. Over months of active trading, this adds up to hundreds of dollars — often more than any welcome bonus.
Welcome bonuses are small, real USDT amounts credited after completing specific tasks — usually a first deposit or a first trade. Typical welcome bonuses range from $5 to $50 across most exchanges. These are actual funds you can use for trading, but they often come with a minimum withdrawal threshold or a holding period.
Futures trial funds are the source of most "up to $30,000" claims. These are not real money credited to your account. They are virtual margin that you can use to open futures positions. You cannot withdraw the trial funds themselves — only profits earned by trading with them. And those profits typically require meeting additional trading volume conditions. For most users, the actual value received from futures trial funds is a small fraction of the advertised number.
Mystery boxes and vouchers are randomized rewards. The advertised value is the maximum possible prize, but the most common outcome is $0.10 to $5 in trading coupons with expiration dates.
In our individual referral code breakdowns, we specify which benefits fall into which category — so you know what you are actually getting.
Conditions You Should Check Before Using Any Code
Every referral bonus comes with conditions. Ignoring them is the most common reason users feel misled by exchange promotions. Here are the conditions that matter most:
Activation deadline. Most welcome bonuses expire if you do not complete the required tasks within a set period — usually 7 to 30 days after registration. If you register today but do not deposit for two weeks, some bonuses may already be unavailable.
Minimum deposit and trading volume. Higher-tier bonuses almost always require a minimum deposit amount and a minimum trading volume. For example, a $100 bonus might require a $3,000 deposit held for 3 days plus $200,000 in futures trading volume. If you are a beginner trading small amounts, these tiers are effectively unreachable.
KYC verification. All major exchanges require identity verification before you can withdraw funds or claim bonuses. Some bonuses only activate after KYC is complete, which can take minutes to 24 hours depending on the platform and your documents.
Geographic restrictions. Not all referral benefits are available in all countries. Some exchanges block specific regions entirely, while others offer reduced bonuses in certain jurisdictions. We note known restrictions in each individual code page.
Non-stackable codes. You can use only one referral code per account. Codes cannot be combined, and they cannot be applied retroactively. Choose carefully before registering.
If a code page on Promokoin does not mention a specific condition, it means the exchange has not disclosed it in their public documentation — not that it does not exist. Always review the exchange's own terms page before depositing.
