Binance requesting Source of Funds (SOF) proof is a standard process to fulfill anti-money laundering compliance obligations, not targeted at any individual. When you receive the request, simply follow the guidelines to submit. Incomplete documents or an illogical chain of evidence are the main reasons for rejection.

The core principle of submitting materials is to form a complete and clear fund chain, from the "source of funds" to the step of "depositing into Binance," with no gaps in between.
Step 1: Distinguish "Source of Funds" and "Source of Wealth"
First, determine whether Binance is asking you to prove "where this specific funds about to be deposited come from" (SOF) or "how your entire wealth has been accumulated" (SOW).
Method: Log into your Binance account and check the specific request description in the [Task Center] or [Verification Center].
Situation A: Asking to explain "where the funds came from," or "require proof of the specific source of the deposited funds" → This is Source of Funds (SOF). You need to prove the source of this specific funds about to be deposited into Binance. Focus on preparing proof directly related to this particular funds. For example, if you sold a car and deposited the money, provide the car sale contract and bank statement.
Situation B: Asking to explain "how you accumulated your current total assets" → This is Source of Wealth (SOW). You need to prove the accumulation process of your entire wealth over a longer timeframe. Provide documents reflecting your long-term wealth accumulation, such as multi-year payslips, company equity certificates, inheritance documents, etc.
Completion standard: You have clarified whether you need to prepare "transaction flow evidence" or "wealth accumulation evidence."
Step 2: Prepare Corresponding Supporting Documents Based on Your Source of Funds
According to your actual situation, choose the easiest and most compelling evidence from the officially recognized document list.
"Salary income": Provide payslips from the last 3 months, or bank statements showing salary deposits from your employer.
"Sale of cryptocurrency": Provide screenshots or statements from the trading platform or wallet, clearly showing the withdrawal record and deposit record, including date, currency, amount, and TxID.
"Deposits/Savings": Provide bank statements for your savings account issued within the last 3 months.
"Self-employment/Company operations": Provide tax returns for the previous tax year, the latest profit and loss statement, or company bank statements.
Completion standard: You have at least one complete, clear supporting document dated within the last 3 months that directly corresponds to the source of funds you claim.
High-risk warning: Do not submit cropped or altered documents. Official requirements state that documents must be clear, complete, and unedited. Blurry screenshots, photos showing only half the screen, or images covering key information will be rejected outright. If a video is required, it must be shot in one continuous take without editing, and you must show your face at the beginning or end while clearly demonstrating the entire process of logging into an external platform and viewing records.
Step 3: Build a Complete Evidence Chain and Organize by Timeline
Organize scattered materials into a timeline that tells a clear story, allowing the reviewer to understand the complete path of the funds at a glance.
Starting point (prove the money is yours): The account name on the documents matches the name on your Binance identity verification.
Process (prove the money comes from the means you claim): Salary deposit records, crypto sale withdrawal records, etc.
End point (prove the money entered Binance): The order record of your deposit into your Binance account.
Example: If your process is "sell crypto - withdraw - deposit," provide the withdrawal record from your selling platform (including TxID and amount) and the deposit record in your Binance account, ensuring that the currency, amount, and approximate time match on both sides.
Completion standard: The materials you have can form a closed loop chain of "where the money comes from → how the money reaches you → how you put the money into Binance."
Common Reasons for Review Failure
The most common issue is "logic mismatch." For example, you claim the source of funds is salary, but the bank statement you provided shows a large transfer labeled as "house sale proceeds." The reviewer will definitely ask you to provide additional proof of the house sale upon seeing this discrepancy. Another common mistake is providing only screenshots that are incomplete, not showing the URL, date, account name, and other key information.

Post-Submission Verification and Notes
Log into Binance, go to [Wallet] - [Task Center] or [Verification Center], and check the status of your submitted application. If it shows "Pending review," just wait patiently; if it shows "Review failed" or "Additional documents required," the system will indicate the reason, and you should prepare again as prompted.
After submission, the materials will be reviewed by the risk control team. Processing time varies and usually takes several business days. During this period, pay close attention to Binance internal messages and your registered email. If additional materials are needed, you will be notified through these two channels. If the documents are complete and compliant, your account functions will return to normal after the review is approved.
