This tool was created after seeing a growing number of artists including cryptocurrency donation QR codes on their artwork.
In order to keep their artwork as clean as possible, most artists limit their artwork to include only a single donation QR code, but this restricts donations to only those who own the single cryptocurrency.
One of the many use cases this tool enables is allowing artists to provide a single QR code on their artwork, but accept donations in any number of cryptocurrencies. And if they later decide to change the receiving address of a wallet, they can easily change the address online instead of having to paint over the old QR Code.
