How to Choose a Transaction Purpose for Crypto Asset Transfers?
In some cases, you may be asked to provide additional information and supporting documents about the source of the funds or assets in your OKX TR account.In this article, you can learn what Source of Funds (SoF) and Source of Wealth (SoW) mean, why we may ask for this information, and which documents you can provide depending on your source of income or assets.
What are Source of Funds (SoF) and Source of Wealth (SoW)?
Source of Funds (SoF) refers to where the funds used for a specific transaction came from.For example, your source of funds may include:
Salary or pension income
Business income
Investment income
Proceeds from the sale of crypto assets
Proceeds from the sale of property or a vehicle
Inheritance or gifts
Legal settlements or insurance payouts
Income from crypto mining
Source of Wealth (SoW) refers to how you accumulated your overall wealth or assets over time. This may include income earned through employment, business ownership, investments, inheritance, or other sources.
Why do we ask for Source of Funds or Source of Wealth documents?
As OKX TR, we are required under applicable regulations to keep customer information up to date and, where necessary, understand the source of funds or assets used in customer accounts.For this reason, we may ask you to provide information and supporting documents related to your declared source of funds or source of wealth.For example, if you declare your source of funds as salary, you may be asked to provide a payslip or bank statement showing salary payments. If your funds come from the sale of a property, you may be asked to provide the relevant sale document together with a bank statement showing receipt of the sale proceeds.

What happens if my document is not sufficient?
If the required information is not visible in the documents you submit, or if we need more information to verify your Source of Funds or Source of Wealth, we may ask you to provide an additional document.This does not necessarily mean that the document you submitted is invalid. In some cases, more than one document may be needed to show both where the funds came from and how they were transferred to you.For example, in a property sale, the sale agreement may demonstrate the source of the funds, while the bank statement may show that the sale proceeds were credited to your account.
