The OKX referral code is 31435988. Enter it at sign-up to get access to the exchange's new user welcome package, which includes mystery boxes containing up to 10,000 USDT in trading fee rebates and crypto rewards.
OKX ranks among the largest centralized cryptocurrency exchanges globally, offering deep liquidity across both spot and derivatives markets. To attract new volume, the platform uses a gamified onboarding system. Instead of flat cash payouts, new users earn mystery boxes by completing basic account milestones.
How to apply the code
The referral system is strictly for new accounts. You cannot apply a code after your account is created.
Download the OKX mobile app or visit the official website.
Begin the registration process using an email address or mobile number.
Locate the field labelled "Referral code (optional)".
Type 31435988 into the box exactly as shown.
Finish creating your account and complete standard identity verification (KYC).
What the bonus actually pays
The heavily advertised 10,000 USDT figure is a maximum potential prize, not a guaranteed cash deposit. When you register with the OKX referral link code and make a qualifying deposit—typically $50 or more within the first 14 days—you receive a mystery box.
Most boxes contain trading fee rebate vouchers worth between $2 and $10. These vouchers sit in your rewards center and automatically reimburse the fees you pay when executing spot or futures trades. Occasionally, boxes yield direct crypto drops like small amounts of BTC, ETH, or OKB tokens. Direct crypto can be withdrawn or traded, while fee vouchers cannot.
Trading fees and rebates
Base trading fees on OKX start at 0.08% for maker orders and 0.10% for taker orders on the spot market. Futures fees are even lower, starting at 0.02% for makers and 0.05% for takers. The rebate vouchers won from your referral mystery boxes apply directly against these rates, allowing new traders to operate virtually fee-free until the voucher balance is completely exhausted.
Risk and eligibility
Cryptocurrency trading carries a high level of risk and is not suitable for all investors; you should never trade solely to clear a promotional bonus. The OKX referral program is entirely dependent on your jurisdiction. The exchange does not operate in the United States, and users in restricted regions cannot complete the verification process required to unlock the mystery boxes.
