No. OKX describes OKX Web3 Wallet as a non-custodial, multi-chain wallet: you hold the seed phrase or private key, the wallet needs no identity verification or account login, and a lost seed phrase cannot be recovered. The OKX exchange account is a separate sign-up that uses identity verification to raise deposit and withdrawal limits. A referral code belongs to the exchange account and must be added before that account is created.
