You can contribute cash to your Daffy fund by linking your bank account (via Plaid), through Apple Pay™, and with all major debit or credit cards. One of the ways Daffy encourages its members to make giving a habit is by making it easy for you to automatically set cash aside for charity, weekly, monthly, or annually by linking your bank account.
You can also contribute non-cash assets. Daffy accepts most publicly-traded stock, ETFs, and mutual funds, over 200 cryptocurrencies, and you can even transfer an existing donor-advised fund to Daffy.
