After an ERC-20 transfer, executing code is not possible. Gas fees must be paid twice in order to submit another transfer.
EthereumPay makes token payments easier than ever before, without any monitoring. It creates a callback after each transfer or approval in a single transaction.
We have created a protocol (ePayProtocol) that will allow us to utilize the ERC-1363 contract and xDai side chain to achieve near-instant transactions for pennies. With this protocol, you can create an easy-to-use and implement crypto invoice system, crypto subscription service, payment gateway and a token payable crowd sale.
