Process
Initiating
With a determined focus on addressing cross-border payment challenges, a team of experts, including a Project Manager, Business Analyst, and Technical Architect, was assembled to spearhead the project. They established effective communication channels, such as regular video conferences and collaboration tools, to ensure seamless information exchange. Deadlines, budgetary constraints, and project scope were defined to align with all expectations and project goals. Recognizing the value of firsthand insights, a site visit to the client’s location was planned, allowing the team to immerse themselves in the client’s operations, understand their unique requirements, and foster a stronger partnership based on trust and collaboration.
Discovery
Thorough research was undertaken to gather requirements and gain deep insights into the market and target audience. This process involved meticulous documentation preparation, including the creation of design specifications and mapping out the technical solution.
Planning
Modsen blockchain payment solution development experts adopted Agile methodologies, with two-week sprints planned to facilitate iterative development and regular feedback loops. They created a comprehensive project plan, outlining tasks, timelines, and deliverables.
Development
Infrastructure
The team embarked on setting up the blockchain infrastructure, selecting the Ethereum platform for its robustness and scalability. They established nodes, secured communication channels, and set up a secure environment using SHA-256, HMAC, and SSL/TLS protocols. AWS cloud infrastructure was leveraged to ensure scalability and availability.
Architecture
Placing great importance on scalability and security, Modsen’s developers designed a growth-oriented architecture that integrated seamlessly with existing payment gateways and networks. The architecture leveraged the chosen blockchain platform, Ethereum, and incorporated off-chain solutions for enhanced scalability. The database management system of choice was MongoDB, providing secure storage for transaction data.
Code implementation and QA
The solution was implemented using the selected tech stack, including HTML5, CSS3, JavaScript for web development, Node.js and Express.js for backend development, and Docker for deployment. The smart contracts were written in Solidity, utilizing the Truffle framework for smart contract development, testing, and deployment. Comprehensive quality assurance processes, including unit testing with Mocha, were employed to maintain the stability and reliability of the custom blockchain-based payment solution development.
Regular demos
It was essential to conduct regular demos for the client, showcasing the progress made on the platform’s development, allowing the team to get timely valuable feedback for further refinement.
Third-party audit
To assess the security, compliance, and overall quality of the software, an external audit was conducted. The audit encompassed the entire tech stack, including the blockchain infrastructure, smart contracts, code implementation, and security measures, providing an unbiased evaluation and ensuring a robust and secure blockchain payment platform.
Acceptance testing
Prior to moving on to the project’s final stage, the client and the development team collaborated closely to identify and resolve any potential issues during the acceptance testing phase. They used various scenarios that encompassed different transaction types and volumes, guaranteeing the solution could seamlessly handle the expected load with optimal efficiency.
Closing
Once the software was in production, a seamless transition was achieved by transferring the full code and providing comprehensive technical documentation. Additionally, a user guide was created to effectively assist clients in navigating and utilizing Modsen’s expertise in blockchain-based payment solutions.
