Why do you need to use a referral code for rebates? The OKX Wallet has started charging transaction fees. For every transaction you make, a transaction fee will be deducted. By using the referral code: AAA888, 20% of the transaction fee you pay will be automatically refunded. Why not take advantage of it! Currently, 20% is the highest rebate the wallet can offer. How is the 20% rebate returned? 20% of the transaction fee you pay will be automatically refunded, no action needed from you or me. On the OKX chain, the rebate will be returned in OKB tokens; on the ETH chain, it will be returned in ETH tokens; and on the SOL chain, it will naturally be returned in SOL tokens. Just enter the referral code AAA888 to activate it.
