Stripe deposits your donations (less our fees and credit card processing fees) into the bank account you provide to them on a rolling 2-day basis throughout your contest.
This means that your funds are available to you almost immediately.
(Your first deposit may take up to 7-14 business days. You can read more at Stripe's website).
