Accept crypto donations with a link for any amount

A project or non-profit accepts crypto donations with Crypto Merchant by creating a payment link without a fixed amount and putting it behind a Donate button. Donors type what they want to give, pick a coin from the ones you accept and pay; every donation appears in your portal and can be exported as CSV, and you pay out to your own wallet at any time. Sign-up asks for no documents, there is no monthly fee, and the fee is 1% per paid invoice.

At a glance

Topic	How it works
How donors give	They open your link, enter an amount, pick a coin and network, and send the exact amount shown to an address made for that gift.
What you need	An account and one payment link. No website is required: the link works in a bio, an email or a chat as well as behind a button.
Smallest donation	0.50 US dollars per gift.
Records	Every donation is an invoice in the portal, with the coin, amount and time; Reports exports them as CSV.
Monthly giving	Not automatic. A wallet can't be debited, so recurring donors use the same link each time.
Documents to sign up	None. Registered-charity status isn't required; the Terms prohibit fraud and misleading people about what they are paying for.

How does it work, step by step?

From a new account to the first gift:

1
Create your account
Sign up with an email address, your name and the project's name. No documents are requested.
2
Choose the coins donors can use
Under Settings, turn on the coins and networks you want to receive. Stablecoins such as USDT and USDC keep the value steady; Bitcoin is what many donors already hold.
3
Create a Donate link with no fixed amount
Open Payment links, choose Create payment link, give it a title such as “Support our work”, and leave the amount empty. The donor enters an amount when they open it.
4
Put the link where donors are
Behind a Donate button on your site, in your email footer, in a social bio or in a chat. Each gift becomes its own invoice with its own deposit address, so you always know which gift is which.
5
Pay out, or hold
Withdraw to your own wallet addresses whenever you like, with no minimum. Or choose one holding coin, such as USDC, so gifts in other coins are swapped into it.

The one API call it takes

The Donate link from the API

curl https://cryptomerchant.online/api/v1/payment-links \
  -H "Authorization: Bearer $CM_SECRET_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "Support our work",
    "currency": "USD",
    "description": "Any amount helps. Thank you."
  }'

# No "amount": the donor types what they want to give.
# 201 → { "id": "…", "url": "https://cryptomerchant.online/pay/l/…", … }  Put the URL behind a Donate button.

What does it cost?

1% of each paid invoice, deducted when the payment is credited to your balance. There is no setup fee, no monthly fee and no payment to go live; expired and cancelled invoices cost nothing. Moving coins (sweeps, swaps and payouts) carries a gas fee, taken from your gas balance if you add one, otherwise from the coins being moved. Customers also pay a gas fee on each invoice: it is added to the amount they send, shown at checkout and never more than $5. Swap rates include a 1% service margin. Every cost is in one table on Pricing.

What Crypto Merchant doesn't do here

No donor wall, goal bar or tax receipts. Crypto Merchant records each gift; thanking donors and issuing receipts is yours.
No automatic monthly donations. Donors give again by opening the same link.
Custodial, crypto-only. Gifts collect in a pool wallet Crypto Merchant holds until you pay out to your own addresses. There is no conversion to a bank account.

Who is this for?

Open-source projects, creators and community groups taking gifts from anywhere.
Non-profits that want donations in stablecoins without running their own wallets.
Anyone who needs a Donate link in minutes, with no documents to send.

Frequently asked questions

Can donors choose how much to give?

Yes. Create the payment link without an amount and the donor enters one when they open it. The minimum is 0.50 US dollars.

Do donors need to register?

No. They open the link, pick a coin and send the amount from their own wallet. There is no donor account.

Can I accept monthly crypto donations?

Not automatically. A crypto wallet can't be debited, so a recurring donor opens the same link each month. You can email them a reminder with the link.

Does Crypto Merchant issue donation receipts?

No. Each gift is recorded as an invoice with the coin, amount and time, and Reports exports them as CSV, but receipts and tax letters are yours to issue.
