Approving the Paytr smart contract and initiating a payment

One of the prerequisites of making a payment is approving the usage of the ERC20 token you'd like to use. You can read more about approving tokens here.

Approve ERC20 tokens using the Paytr app

The Paytr frontend automatically checks the approved amount (aka 'allowance') per ERC20 token for the connected account. Should you want to make a payment without sufficient allowance, the app will ask you to increase the allowance first.
