Give Crypto, Stock, or a DAF Grant — Every Gift Fuels Kleefstra Syndrome Research
IDefine is a nonprofit organization dedicated to advancing research, building community, and driving progress that can lead to new treatments, and eventually a cure for Kleefstra syndrome. Now you can support that work with appreciated assets — often more tax-efficient than cash, and just as easy.
Give Now →Cryptocurrency
Donate Bitcoin, Ethereum, USDC, and 100+ other cryptocurrencies directly. Because the IRS treats crypto as property, donating appreciated coins directly to IDefine means neither you nor IDefine owes capital gains tax — so more of your gift goes straight to research.
Stock & Securities
Give appreciated stock, mutual funds, or other securities directly from your brokerage account. You can avoid capital gains tax and may be able to deduct the full fair market value of your gift.
Donor-Advised Fund
Already have a Donor-Advised Fund (DAF)? Recommend a grant to IDefine in just a few clicks — no paperwork, no phone calls, no waiting.
Is my crypto or stock donation tax-deductible?
Generally, yes. Donations of appreciated crypto or stock held for more than a year are typically tax-deductible at fair market value, and you avoid the capital gains tax you'd owe if you sold the assets yourself first. Every donor's situation is different, so please consult your tax advisor for guidance specific to you.
Is this secure?
Yes. Your donation is processed on a secure form hosted by The Giving Block — IDefine never sees or stores your wallet or brokerage credentials.
What if I'd rather give cash, check, or card?
All welcome! You can make a traditional gift any time through our Donate Now page.
What if my stock or mutual fund ticker symbol doesn't appear in the widget?
Some securities — especially mutual funds — aren't listed in the widget and must be transferred manually. Email unlock@idefine.org with your name and the ticker symbol you'd like to give, and we'll send you the transfer instructions your brokerage will need.
Who can I contact with questions?
We're happy to help — email us at unlock@idefine.org or reach out any time through the contact form in our site footer, and a member of the IDefine team will get back to you.
