Proof of source of funds (POSOF)
This article is tailored to clients located in Germany. If you are not based in Germany please visit this article!
A proof of source of funds (POSOF) document explains where the funds originated from for a bank deposit, crypto deposit, or where the crypto assets used for a cash withdrawal originated. POSOF may also include cryptocurrency balances, on exchanges or self custodial wallets.
We reserve the right to request a proof of source of funds for clients depositing or withdrawing cash/crypto.
Any POSOF document submitted needs to cover all deposits or withdrawals made via the relevant funding method in the last 30 days. Ensure that the POSOF documentation you provide covers any previous deposits or withdrawals within this time frame as well as the most recent one. Additionally, if applicable, a signed message from the originating crypto wallet may be required.
