This project repository represents a pay-to-earn promotion where a gas station owner can offer their customers rewards through gasoline purchases. Rewards can be accumulated, exchanged for unique NFT art ("Oil stains”), or donated to a non-profit of their choice. The NFT’s are kept in the IPFS network - Infura. The administrator manages the promotion and the customer decides how to use their rewards.
