Accepted coins/tokens and exchange fees

We have integrated Crypto for Charity with Coinbase and Gemini exchanges, which means we can process donations for any cryptocurrency supported by Coinbase and Gemini.

See the links below for more info on the accepted cryptocurrencies for each exchange:

• https://support.gemini.com/hc/en-us/articles/115005868106-What-cryptos-are-supported-on-the-Gemini-Exchange

If a coin/token you want to donate isn't available, please reach out to us. We might be able to process your donation manually over the counter (OTC).

Also, please let us know in advance if you're planning on donating more than $100,000 USD worth of crypto because we can work with our exchange partners to ensure a more favorable spread when selling large donations.

While we don't charge any fees to process donations, crypto exchanges will take their usual small fee. See below links for more information on Coinbase and Gemini exchange fees:

IMPORTANT

When you send crypto assets using multiple blockchain networks, you need to confirm that you're using the correct supported network prior to initiating the transaction. You may permanently lose funds that are deposited to an unsupported network.

When using the dropdown in our donate cryptocurrency flow to select a coin/token you want to donate, we note the specific network in parenthesis.

Examples:

If you choose "Matic (MATIC-ERC20)", it means you will be creating a dedicated donation address for Polygon (MATIC) tokens on the Ethereum network (using the ERC20 token standard).

When sending your donation to this address, you must make sure you are sending the ERC20 version of MATIC.

Another example: If you choose "Ether (ETH-BASE)", this means you should be sending Ether on the Base network.

Note: Since the donation wallets are in the custody of centralized exchanges, looking at the crypto transactions in a block explorer doesn't always tell you what has happened to a specific donation.

Exchanges often leave the crypto in the wallet (or move it around as they wish) and use their existing USD reserves whenever crypto is sold by an exchange customer. They typically use internal ledgers to keep track of customers' assets so it's also not uncommon for them to mix different customers' assets in the same wallet.
