To ease the payment process, Malt uses a prepayment system

This insures a quick and secure payment. 

With the MangoPay payment platform, it is possible to block the payment amount on an account (which belongs neither to the client, nor to Malt) for the duration of the mission. 

This way, you can work knowing that you will be paid at completion. The funds are released and transferred to your bank account when both you and the client confirm that the mission has ended.
