The problem with the the current applications is they support only the traditional FIAT currencies like USD, Euro, Pound for the transactions between the creator and supporter. Also there are significant intermediary charges which are being levied on the user by the banks and payment gateways. We started up with a solution ny implementing the BuyMeCoffee with SOLANA.Through our application, the anyone can create their custom link with a "buy-me-coffee" button which performs the transfer of $SOL from sender to receiver.
Currently the project runs on devnet wallets,We are planning to include some additional features like selling custom merchandise. We will be live shortly at: solbucks.pythonanywhere.com
