Digital payment solution

We built a digital payment processing solution by designing a payment engine from scratch that could process both FIAT and crypto transactions, conforming to ISO 20222 standards. The first step was to research and understand the requirements of ISO 20222, including the necessary data fields and transaction flows. We then created a technical design for the payment engine, including a secure database to store transaction information, a payment gateway to facilitate transactions, and a user interface for customers to initiate and manage payments. To handle both FIAT and crypto transactions, we integrated multiple payment methods, such as credit cards, bank transfers, and cryptocurrency wallets. We also implemented strict security measures, such as encryption and secure authentication, to ensure the safety and confidentiality of our customers' payment information. After thorough testing and fine-tuning, we launched our digital payment processing solution, offering a seamless and secure way for customers to make and receive payments in both FIAT and crypto
