Step 1: Locate the Source of Funds Verification Entry
What to do: Find the submission page for the Source of Funds verification (additional authentication) in the OKX App.
How to do it: Choose from three scenarios:
- Scenario A: Received a system notification or in-app banner: On the OKX App home screen, tap the [Please provide information] banner, and you will be taken directly to the verification page.
- Scenario B: No banner, but want to proactively check/submit materials: Go to OKX App home → tap the [All Functions] icon top left → [Profile and Settings] → [Profile] → [Identity Verification] → [Verify Now].
- Scenario C: Using the web version: Log in to the OKX website, click your [Profile Avatar] in the upper right corner → [Identity Verification].
Completion criteria: You have reached the identity verification page and can see the questionnaire or submission entry related to Source of Funds (SOF).
Step 2: Select the Correct Source of Funds Type and Submit Documents
What to do: According to the system requirements, select the source of funds option that matches your actual situation and upload the corresponding supporting documents.
How to do it: In the Source of Funds questionnaire, choose a [recent and primary] source of your deposits. Options include but are not limited to: personal salary income, sale of assets, borrowed funds, gifted funds, funds from other personal exchange/wallet accounts, etc.
- Scenario A: Source of funds is "transfer from another exchange/wallet": This is the most common case. You need to export an account statement (PDF) covering the last 3 months from the source platform, showing your real-name account information and relevant transaction records. If the funds come from an on-chain wallet, choose the corresponding source option and provide on-chain transfer records and an explanation.
- Scenario B: Source of funds is "salary income": Provide payslips or bank statements for the last 3–6 months showing your name and salary payment records.
- Scenario C: Selected the wrong source of funds type: The system does not lock you out. You can click [Update Now] in the additional verification item to reselect the correct information and provide the matching supporting documents.
Completion criteria: You have submitted supporting documents that match the selected source of funds type, and the files are clear, complete, and unedited.
High-risk warning: If the submitted documents are blurry, cropped, obscured, or have unclear amounts, the verification will fail directly. Another common reason for rejection is providing proof for the wrong entity – for example, funds came from another platform, but you provided OKX's own deposit screenshot. The correct approach is to provide the account statement from the platform where the funds were sent from, to prove the authenticity of the source of funds.
Step 3: Check Supplement Status and Progress
What to do: After submission, track the review status and confirm if any additional materials are needed.
How to do it: Return to the [Identity Verification] page to view the status. OKX official note: Review specialists usually complete the assessment within 24 hours.
- Scenario A: Status shows "Under review": Simply wait. During this period, keep an eye on notifications in the [Message Center] of the App or your registered email.
- Scenario B: Status shows "Additional documents required" or "Verification failed": The system will indicate the reason for rejection. Add the requested documents and resubmit, or click [Update Now] to change the source of funds type.
- Scenario C: No update after 48 hours: Contact OKX customer support with your ticket number to inquire about the progress.
Completion criteria: You have confirmed the current review status and know what to do next (wait / supplement / modify).
