What a referral code changes
One string per desk. It attributes the signup. It does not rewrite the fee schedule or the country list.
Short answer
On LiquidityFlow the promo code and the referral code are the same string. The partner link carries it, except Tapbit, where you type 42042069, and KCEX, where this desk publishes no code. The code does not attach another site's welcome bonus, fee rebate, or a lower schedule. An existing account is not retiered by opening the link.

What it does
If the partner link carries the code, opening the button is how the exchange sees the attribution. On the signup screen, confirm the field shows that code before you submit. If the field is empty, type the code with no spaces. Tapbit is the exception already in the table: the button is the official homepage, and you type 42042069.
LiquidityFlow may earn a commission when the exchange attributes the signup. The commission is not a discount printed on the fee board.
What it does not do
- It does not attach another site's welcome bonus, lifetime discount, or fee rebate to our code.
- It does not replace the copied taker rate. Those rates, and the 1,000 USDT round trip, stay on the cost hub.
- It does not change KYC or the restricted-country list. Read restricted countries before you sign up.
- It does not retier an account you already opened. The promo pages say so desk by desk.
- A campaign voucher, where the exchange publishes one, is a separate document with its own cap and expiry. The Bitbase trial-fund tiers are on the Bitbase promo page, and the volume math is on campaign math.
Questions
Are the promo code and the referral code different?
Not on this desk. Each promo page uses one string for both. If a partner link exists, that link carries the string.
Which desk has no code?
KCEX. The registration link is KCEX's official form with no code attached. The fee row is still on the board.
Which code do I type myself?
Tapbit, 42042069. The button opens tapbit.com and does not insert the code. The other published codes are carried by the partner link.
Does the code lower the taker fee?
This desk does not attach a fee rebate to its codes. The round trip on the cost hub is the copied schedule, not a discounted schedule. A campaign voucher, where one exists, is a separate document.
Can I add the code after I already have an account?
The promo pages say an existing account is not retiered by opening the link. Create the account only if the field shows the code before you submit, or type it when the form asks.
Does the code change KYC or the country list?
No. Verification and restricted countries are the exchange's. The code is attribution for the partner link.
Does LiquidityFlow earn a commission?
Yes, if the exchange attributes the signup to our link or our code. That commission does not change the fee table on the page.
Where is the list of codes?
On the promo codes index, and again in the table on this page. Each code links to its own promo page.
