The most direct reason your deposit is frozen by risk control is that the platform's system detected something unusual about the on-chain source of the funds. OKX has officially stated that if a user deposits funds from a sanctioned entity such as Tornado Cash, or withdraws from OKX to such an address, it will trigger compliance risk control and may lead to account closure.

What you need to do is not argue with customer support about "why me," but prepare the correct proof documents based on the nature of the source. The documents themselves are not hard to prepare; the hard part is submitting the right ones the first time.
Step 1: Understand the Common Triggers for Risk Control Freezes
Funds are usually frozen for the following reasons:
Source address risk label: The wallet address you used to receive USDT on-chain has been used for coin mixing, interacted with sanctioned addresses, or is flagged as high-risk.
C2C counterparty risk: When buying crypto via C2C, the bank account used by the counterparty was involved with illegal funds, and the risk control system restricts your account as a result.
Large deposit triggers automatic review: Your account has low historical trading volume, and you suddenly deposit an amount far exceeding your normal pattern.
Regional compliance requirements: Accounts in certain regions need to complete additional Travel Rule verification, otherwise deposits will be locked.
Determine the risk level: If only a single transaction is locked but other account functions are normal, it is a "partial restriction". If the entire account is frozen, it is a "full restriction" and you need to follow the ticket process to unfreeze each part.
Step 2: Prepare the Correct Documents Based on Your Source of Funds
OKX's SoF/SOW verification process requires you to provide documents proving the legal source of these funds. Different source types require completely different documents. Choosing the wrong type will lead to direct rejection.
| Source of Funds Type | Documents Required | Validity Period |
|---|---|---|
| Salary/Employment Income | Last 3 months of payslips + Bank statements showing "salary" deposits + Employment contract or proof of employment | Within last 3 months |
| Self-employment/Business Income | Business license + Last 3 months of commercial bank statements; or service contracts/invoices/profit and loss statements | Within last 3 months |
| Sale of Property/Vehicle | Asset sale agreement + Bank receipt records + Tax payment proof | Period when the sale occurred |
| Investment/Trading Income | Stock/fund account statements; or exchange trading records exported (including name, amount, date) | Within last 3 months |
| From another exchange wallet | Transaction history export from the source exchange (CSV/PDF showing your name or wallet address) + Bank statement showing the withdrawal record | Within last 3 months |
| From a non-custodial wallet | Screenshot or export of wallet transaction history + A signed message proving you own the wallet | Corresponding transaction date |
| Mining Income | Mining pool income report + Equipment purchase receipt or electricity bill | Within last 3 months |
| Gift/Inheritance | Notarized gift letter or will + Bank transfer records | Corresponding occurrence date |
If the source of funds is "transferring money from Exchange A to Exchange B and then depositing to OKX", you need to provide the transaction history export from the source exchange, not a screenshot of your OKX deposit. The platform wants to see where the money originally came from, not which intermediate stop it passed through.
Step 3: Submit Documents Through the Official Portal
Path: Log in to the OKX App → Tap the banner at the top of the homepage [Please provide information] → Enter the identity verification page → Select the source of funds type and upload files. If there is no entry on the homepage, go to [Profile] → [Identity Verification] → [Verify Now] to check if there is a pending questionnaire.
Web path: Top right corner [Profile Avatar] → [Identity Verification].
If the ticket does not clearly list the document submission entry, check your registered email — OKX customer support will send specific instructions and requirements via email. The email may have been mistakenly sent to your spam folder.
Completion standard: Successfully upload all required files on the ticket page in the App or web version, and confirm that the page shows "Submitted".
Three Strict Requirements for Document Preparation
According to OKX's official review standards, submitted materials must meet the following requirements, otherwise they will be rejected:
Clear and readable: Place documents on a flat surface with sufficient lighting when taking photos. All four corners must be fully visible. Blurry, cropped, or obscured documents will be rejected.
Information consistency: The name on the document must exactly match the name on your OKX identity verification.
Non-editable format: PDF, JPG, and PNG are accepted. Excel and Word files will be directly rejected.

Consequences of Not Responding Before the Deadline
If you do not submit the required materials within the specified time, account restrictions may be extended and account functions may be suspended until the required information is received. It is recommended to submit complete materials as early as possible to shorten the account restriction window.
How to check completion status: After submitting materials, follow status updates through the ticket center or your registered email. The typical review period is 1-3 business days. If you do not receive a reply within 48 hours, contact online customer support and provide your ticket number to check the progress.
