How to Understand Binance’s Source of Wealth (SoW) Explanation?
When Binance asks you to explain your source of wealth, it essentially wants you to clarify the origin of your total assets. This is part of the "Know Your Customer" (KYC) process under the anti-money laundering (AML) framework, used to confirm that your wealth was not accumulated through illegal activities.

Step 1: First Understand What SoW Is – It's Not the Same as SoF
What to do: Separate "Source of Wealth (SoW)" from "Source of Funds (SoF)" – this is the key to understanding the whole process.
How to do it:
Source of Wealth (SoW) – "Overall Ledger": Refers to how you accumulated your total wealth to date. It covers all your assets (including illiquid assets such as real estate and company equity), and may be a combination of career earnings, business investments, inheritance, and more.
Source of Funds (SoF) – "Specific Deposit": Refers specifically to where the money you deposit into your Binance account came from. It must be a liquid asset (cash, deposits), usually derived from your wealth, but sometimes from a one-time asset sale or other means unrelated to regular income.
An analogy: SoW is like asking "how you earned your money over your lifetime," while SoF asks "is this deposit today from your salary or from selling a house?"
When this is done: You understand that Binance wants an explanation of your overall accumulation process, not just how your most recent deposit came about.
Step 2: Understand Why SoW Is a Mandatory Requirement
What to do: Realize that SoW is not the platform "checking up on you"; it's a statutory part of AML compliance.
How to do it:
Legal obligation: As a regulated platform, Binance must comply with global anti-money laundering (AML) and counter-terrorism financing regulations. Verifying assets and the source of funds is part of enhanced due diligence and a core element of AML policy.
Prevent illicit funds: After KYC verifies identity, the platform also needs to deeply understand your on-chain behavior through KYT (Know Your Transaction) to prevent risk funds from contaminating the platform.
Trigger timing: Typically requested when risk control models are triggered, such as when an account shows suspicious transactions, has fund movements linked to sanctioned addresses, or after a large deposit.
When this is done: You understand that SoW is part of a compliance review, not a targeted personal inquiry.
Step 3: Understand the Acceptable SoW Types and Supporting Documents
What to do: Match your wealth accumulation pattern to a specific type and prepare the corresponding documents.
How to do it, compare with the following common types (source: Binance official guide):
| Source of Wealth Type | Example Documents |
|---|---|
| Employment income (including self-employment) | Last 3 months' payslips + employer's letter; or salary bank statements for the last 3 months; or latest tax return |
| Business income | Latest balance sheet/financial report (signed by an accountant); or tax return showing income |
| Investment returns | Cryptocurrency account statement (including UID, email, holdings and trading history); or wallet screenshot (including address, holding amounts); or tax return showing cryptocurrency gains |
| Sale of real estate or other assets | Sale/settlement contract (including asset type, price, parties and date) + bank statement showing proceeds; or tax return declaring sale profit |
| Inheritance | Certified copy of will by a lawyer or accountant; or statement of asset distribution issued by a lawyer |
| Gift/Donation | Gift declaration signed by donor (last 3 months) + bank statement showing the gift transfer record |
| Cryptocurrency mining | Proof of mining equipment purchase; or all mining income records from mining pool/platform (at least 3 months) |
When this is done: You have identified your SoW type and are preparing the corresponding supporting documents.
Step 4: Ensure Your Documents Meet the "Golden Rules"
What to do: Check your materials against Binance's document standards to avoid rejection due to formatting issues.
How to do it, verify each item:
Issued in your real name: The name on the document must exactly match your Binance account name.
Clearly legible: Use high resolution (recommended 300 DPI), all four corners of the document must be fully visible, not cropped, blurred, or watermarked.
Unedited: Only uneditable formats (PDF, JPG, PNG) are accepted; Excel or Word are not accepted.
Recently issued: The document should reflect recent financial activity (e.g., payslips from the last 3 months, or tax return from the last year).
Format requirements: Screenshots must show the entire page, including the URL and your/your company's name and date.
When this is done: All your documents meet the above criteria and are ready for upload.

Common Misconceptions
"My source of wealth is just crypto trading, I don't have payslips – how do I prove it?" Cryptocurrency investment returns are themselves an accepted type of source. You need to provide an exchange account statement (including UID, holdings, and trading history) or wallet screenshots to prove it. If you cannot provide traditional income proof, simply prepare materials under the "crypto investment" route.
Next steps: Log in to your Binance account, go to the [Identity Verification] page, and check whether you are required to complete Enhanced Due Diligence (EDD). If so, select your source of wealth type according to the system prompts, prepare documents following the material checklist in this article, and upload them. After submission, watch for email notifications; the review usually takes several business days. If you have any questions, consult Binance's online customer service.
