SendCrypto

An easy way to send or request cryptocurrency payments.

SendCrypto makes it easy to send or request cryptocurrency payments. You can easily create a link to receive payments through your own page on this site, and share that link with people who might send you money.

A link is built as follows, always excluding quotes:

Any "/" at the end of a URL (in this application) is optional.
For example: If you find this site useful, please click here to send your support.

A more decentralized alternative for building the link, which can be used if your audience uses Brave or Opera or the Unstoppable Domains extension is as follows, always excluding quotes:

For example: If you find this site useful, please click here to send your support.
Note: This strategy of using GET parameters can also be used with traditional domains; any GET parameters will override URL parameters if both are present.

If you want to convert the text link into a QR code that you can post somewhere, there are plenty of free sites which can do this for you (one example is here).
Best practice calls for testing the generated QR code before distribution to verify that your generator didn't change the recipient address.
If you are generating links programmatically, there are also open-source libraries which can convert the text links to QR codes.
