Setting Up Your Account: Essential Pre-Trade Steps

Before initiating any transaction, four critical account configurations must be completed to ensure security and compliance:

1. Complete KYC Verification

KYC (Know Your Customer) verification is mandatory for all users. The higher your verification level, the better your access to liquidity and premium trading opportunities.

On Mobile App:
Go to the homepage → Tap the top-left menu → Select [Identity Verification] → Complete:

On Web Platform:
Log in → Click top-right profile → [Identity Verification] → Complete Level 1 and Level 2.

✅ Tip: Higher KYC levels unlock lower fees, increased limits, and faster dispute resolution during C2C trades.

2. Bind a Phone Number

Security starts with verified contact information.

Mobile App:
Menu → [Security Settings] → [Phone Verification] → Follow prompts

Web Platform:
Profile → [Security Center] → [Phone Verification]

Users who registered via phone can skip this step but should consider adding an email for backup recovery.

3. Set a Fund Password

The fund password protects all withdrawal and transaction activities.

Navigate to:
[Security Settings] → [Fund Password] → Create a strong, unique password

This same section allows you to enable additional protections like:

🔐 Best Practice: Never reuse passwords. Combine 2FA and anti-phishing codes for maximum protection.

4. Add Payment Methods

To receive funds when selling crypto, link your preferred withdrawal methods.

Mobile App:
Home → [Buy Crypto] → [Quick Buy] → Top-right [More] → [Payment Settings] → [Add Payment Method]

Supported options include:

Ensure all details are accurate—incorrect info may delay payouts or result in failed transactions.

Frequently Asked Questions (FAQ)

Q1: Why do I need KYC verification to buy crypto?

A: KYC ensures regulatory compliance, prevents fraud, and enhances platform security. It also unlocks higher trading limits and better pricing on peer-to-peer markets.

Q2: Can I use someone else’s bank account for transactions?

A: No. All payment methods must be under your real-name verified identity. Using third-party accounts violates policy and may lead to fund freezing.

Q3: What should I do if a buyer doesn’t pay after I mark the order as complete?

A: Never click “I’ve transferred” until payment is confirmed in your account. If scammed, immediately file a complaint via [Support]—OKX will investigate and assist where possible.

Q4: Are there fees for buying or selling on OKX?

A: OKX does not charge direct fees for most P2P trades. However, spreads (price differences) act as implicit costs. Always compare offers before confirming.

Q5: How long does it take to receive crypto after paying?

A: Most transactions settle within minutes once the seller confirms receipt. Delays typically occur during non-banking hours or due to incorrect transfers.

Q6: Is it safe to trade large amounts on OKX?

A: Yes—especially with Level 3 verification and two-factor authentication enabled. For high-value trades, use the dedicated large-volume desk for enhanced security and personalized service.
