There are two things needed to complete a Bitcoin payment:
1. the receiving Bitcoin wallet address
2. the Bitcoin amount.
These are displayed on the PayFast engine (and can be copied into the payer's wallet) to complete the transaction.
The Bitcoin payment link, is simply a URL (or in our case a button) that opens up your preferred Bitcoin wallet and prepopulates it with the wallet address and amount. Using it could speed up your payment and help avoid making input mistakes.
These links are currently only supported with Mozilla Firefox and Google Chrome, but other browsers might come on board soon. To set up your browser to handle these links, simply click on the link and follow the prompts.
If you're using the Luno wallet (previously known as BitX), you should visit their website and click on the button to set up your browser.
