October 2026 OKX Referral Code TWBTC | How to Use It & Get 20% Off Fees, Plus Up to 30% APR for the First 3 Days (Full Guide & TWD Deposit)
Referral code: TWBTC
Referral link: https://www.okx.com/join/TWBTC
Offer: 20% off trading fees plus a new-user perk of up to 30% APR for the first 3 days. ⚠️ A referral code cannot be added after registration, and Taiwan dollars (TWD) cannot go directly into OKX; they must pass through a local exchange first.
TWD Gateway Lab (台币进场实验室) writes about how TWD moves in and out of exchanges. This article covers entering the code and depositing TWD together, because many people only notice the missing code after registering, when they get stuck at the deposit step. OKX rules were rechecked against its official pages on 2026-10-12; local exchange fees come from public endpoint readings in 2026-09.

What Is an OKX Referral Code, and What Do You Get?
A referral code is a referral relationship bound at the moment of registration, and entering TWBTC reduces trading fees by 20%. That is OKX's official upper limit and it is the same for every referral code. It is also paid back afterward, so the order page still shows the original rate.
For TWD users it is important to keep this straight: the code saves trading fees, not deposit costs. Deposit costs are cut by choosing the right channel and the right chain; there is a table in the section below on TWD deposits.
The "blind box worth up to 20,000 USDT" in older articles is no longer on the official invitation page, and this article does not cite it.
Where Do You Enter the OKX Referral Code?
Step 1: Open the referral link
Open https://www.okx.com/join/TWBTC. If it will not open, OKX suggests downloading the app first and typing the code by hand on the sign-up page.
Step 2: Enter your email or phone and a password
Using the same email as your local exchange account makes reconciling records easier later.
Step 3: Confirm the field says TWBTC and take a screenshot
On mobile the field may be collapsed. Expand it, confirm, and take a screenshot as evidence.
Step 4: The field shows a code you cannot change
If you clicked someone else's referral link in the last 30 days, the code may be tied to your device. OKX recommends registering on the web version in a private (incognito) window and logging in to the app after the binding.
Step 5: After registering, confirm the binding before depositing
App home grid menu → Account settings → Personal profile → Invitation rewards. If you see it, the code is bound. Confirm first, then deposit, because there is no channel to add the code after the account is created.
Fee Discount Comparison
| Type | Original rate, regular user (maker / taker) | Equivalent after 20% off |
|---|---|---|
| Spot | 0.080% / 0.100% | 0.064% / 0.080% |
| Futures | 0.020% / 0.050% | 0.016% / 0.040% |
How Do You Deposit TWD into OKX? Three Legs and Their Costs
Since 2024-06-24 OKX has not allowed Taiwan users to use TWD for C2C. TWD must first go into a local exchange and be converted to USDT, then be transferred on-chain into OKX:
| Leg | MAX | BitoPro |
|---|---|---|
| ① TWD deposit | No fee; new accounts: 100,000 per transaction and per day, 3,000,000 cumulative within 31 days of registration | See the official page |
| ② Buy USDT (VIP0) | Maker 0.08% / taker 0.16% | Maker 0.1% / taker 0.2% |
| ③ USDT withdrawal fee | BSC 0.02 / Polygon 0.02 / ERC20 0.4 / TRC20 3.0 | BEP20 0.1 / Polygon 0.1 / ERC20 0.3 / TRC20 2.5 |
On these two local exchanges, TRC20 is actually the most expensive chain, the opposite of the common impression that TRC20 is cheapest. Before withdrawing, check which chains OKX's deposit page accepts and pick the cheapest one both sides support. Send a small test amount first, and once it arrives, send the larger amount.
Withdrawal is the same route in reverse: withdraw USDT from OKX back to the local exchange, sell it for TWD, then withdraw to your bank. TWD withdrawals on both MAX and BitoPro cost 30 per transaction, with a minimum of 100.
