Give to Charity Without Giving Away Your Money
Continuous giving that doesn't cost you your deposit.
It's like a GoFundMe where you don't give away your money — and you have a chance to win.
Most giving is a one-way trip: the money leaves your account and it's gone. That's the point of a donation, and it's a good thing. But it also means most of us give less often than we'd like, because every gift is a cost.
Charity Billionaire works differently. You deposit money into a shared pool. It stays yours, and you can withdraw all of it at any time. While it sits in the pool it earns interest, and that interest — not your deposit — is what gets given away. Every week, 5% of the pool's interest goes to a vetted charity, 90% becomes a prize for one depositor picked at random, and 5% keeps the platform running.
What you give, honestly
You aren't giving nothing. You're giving up the interest your money could have earned somewhere else. That forgone interest is what funds both the charity gift and the prize. In exchange, your deposit keeps working for charity every single week for as long as you leave it in, and you get a weekly chance at the prize.
The weekly gift depends on the size of the whole pool and the interest rate it earns, so it moves around. A small pool makes a small gift; as more people deposit, the gift grows. We don't dress that up — the live figures on the home page are read straight from the contract.
Where the gift goes
The charity changes every week, rotating through a curated roster of established nonprofits. This week's and next week's beneficiary are shown on the home page and published on-chain before each draw. The gift is delivered on-chain through Endaoment, a 501(c)(3) donor-advised fund, which grants it to that week's named charity. You can follow every gift on the record of past drawings, or see the current roster on our USDC giving guide.
Why your deposit is safe from the draw
- Your deposit sits in an open, non-custodial smart contract on the Base network. No person or company can move it — the code only lets you withdraw your own balance.
- Only interest above the total of everyone's deposits is ever paid out. Principal is never part of the split.
- No fee to deposit or withdraw, apart from the network's own small gas cost.
That doesn't mean zero risk. It is not insured, and like any on-chain application it carries smart-contract risk, plus the risk of a serious failure in Aave, the lending protocol where the pool earns its interest. Deposit only what you're comfortable holding in a smart contract.
Getting started
You don't need any crypto. Tap “Enter with card” on the home page: your phone saves a passkey (Face ID or fingerprint) that becomes your wallet, you buy USDC with a debit card (purchases start at $5), and you deposit with one tap. Already hold USDC on Base? Connect your wallet instead. Each whole dollar is one equal entry in the weekly draw.
Nothing here is financial, legal, or tax advice, and nothing here is an offer of a security. For anything tax-related, see our Taxes page and speak with a qualified professional. Your deposit is not spent and is withdrawable at any time. Non-custodial and not insured.
