4 Complete Identity Verification (KYC)
To comply with global AML regulations and secure your account, you must complete KYC verification before depositing or trading.
Open the App, tap your profile icon, and select "Identity Verification". Follow the prompts to take a photo of your ID document and complete a quick facial recognition scan. Approval usually takes less than 5 minutes.

Key Concepts Before Registration
OKX referral code: A code entered during sign-up. This page shows 39400540, but eligibility and fee information should be confirmed on OKX.
OKX KYC: Identity verification. Supported documents, review times, and available features may differ by country, region, and account status.
P2P or C2C buying: A way to buy crypto with local payment methods through platform-listed merchants. Always review merchant history, order terms, and platform warnings.
Proof of Reserves: A transparency report that helps users check reserve coverage. It does not remove market, custody, or operational risks.

A closer look at reserve transparency, account security, and Web3 features
Established in 2017, OKX has survived multiple bull and bear market cycles. Following the FTX collapse, OKX quickly established itself as a major global exchange through its commitment to transparency and technical excellence.
1. 100% Proof of Reserves (PoR)
OKX was among the first to implement and consistently publish monthly Proof of Reserves. Using zk-STARK zero-knowledge proof technology, any user can independently verify that their assets are backed 1:1 on-chain, improving transparency around reserve coverage.
2. Risk Control & Cold Wallets
Over 95% of user assets are stored in multi-signature offline cold wallets, with private keys physically distributed among executives globally. Hot wallets utilize semi-offline signatures and strict risk warning systems.
3. Web3 Wallet Features
OKX combines exchange functions with a self-custody Web3 Wallet mode. Users can switch to the Web3 Wallet in the app when they want to manage assets on-chain. It features a built-in DEX aggregator, NFT marketplace, and DeFi yield aggregator.
