Crypto exchanges run the most generous referral programs of any industry — customer lifetime value is high, so exchanges like Kraken, OKX, Coinbase and MEXC can afford to pay real money for a new trader. Rewards here are typically the largest you'll find, but they also carry the strictest conditions: most only pay after you complete identity verification and trade a qualifying amount, and many are paid in crypto that moves with the market between earning and withdrawal. Every code below shows a community-confirmed “% worked” score, so you can see which offers actually pay before you sign up. Read each code's steps carefully, check the region, and finish verification early — that's where most crypto bonuses get stuck. The codes are ranked by real user votes and confirmations, not by anything we're paid.
Kraken is one of the longest-running crypto exchanges, and its referral program rewards new users who sign up, deposit and trade a qualifying amount. Use a community-confirmed Kraken code below for the current sign-up bonus, subject to Kraken's terms.

Compare the reward, region, requirements and worked percentage. The best Crypto referral code is the one you can actually qualify for, not only the one with the biggest headline number.
Most Crypto bonuses are paid only after a qualifying action such as verification, deposit, purchase, trade, completed ride or delivered order. Read the terms on each code before signing up.
Brands change referral campaigns often. Region limits, expired campaigns and missed requirements are the most common reasons a code stops paying, so recent worked reports matter.
