Source of Funds (SOF) and Source of Wealth (SOW)

Understanding the Difference

Source of Funds (SOF): Focuses specifically on the origin of the money used for a particular transaction or deposit. It requires tracing the flow of funds to demonstrate how they were moved into your Cube account.

Source of Wealth (SOW): Examines your overall financial standing and the activities that have contributed to the accumulation of your total net worth over time (e.g., long-term inheritance, business ownership, or career earnings).

Why do I need to provide documents on the Source of Funds and Source of Wealth?

Cube Exchange is committed to the highest standards of financial crime compliance. We strictly enforce Know Your Customer (KYC), AML/CFT, and Sanctions monitoring to protect our clients, our business, and the integrity of the global financial system.

By verifying the source of assets, we ensure that our platform is not inadvertently used for money laundering, terrorism financing, or the circumvention of international sanctions. Transparency is essential to our operations, and we work in close alignment with regulatory authorities to maintain a secure and ethical trading environment.
