Why do we ask for Source of Wealth or Source of Funds Documents?
Kraken takes your security seriously and follows strict laws to prevent money laundering and illegal activities.
To meet these legal requirements, we may sometimes ask for extra information or documents about how you built your overall wealth (Source of Wealth) and where your money comes from for a specific transaction (Source of Funds). This helps us keep your account safe and compliant.
This does not mean you have done anything wrong! In fact, a SOF/SOW document might simply be required based on the country you live in, or because of your current situation, such as being a student or currently unemployed.
