2. Create the account with the email or phone option the form offers.

4. Finish registration and any verification Bybit asks for.

Form layouts change, and what Bybit asks for is Bybit’s call. The box may be labelled referral code or invite code; it is the same field.

What the 20% give-back means

We earn a commission when someone opens a Bybit account through our link, and we pass 20% of that commission back to you as lower trading fees on Bybit. It covers trading fees only: not withdrawal or network fees, and not deposits. Most promoters just share a link; this is the part we hand back.

Referral code, promo code, invite code: the same thing?

People search for it all three ways. A referral code and an invite code are both a code from an existing user that ties your new account to their link. A “promo code” usually means a campaign code the exchange runs itself. chaintool is a referral (invite) code. We list no bonus amount here: any campaign is set by Bybit and changes, so check Bybit’s own site for it.
