The Problem We Were Actually Solving
As a software engineer, I've always been fascinated by the concept of decentralized finance, but my excitement quickly turned to frustration when I realized that living in a restricted country makes it nearly impossible to receive traditional payment for my digital work. Cryptocurrency seemed like the perfect solution, but it quickly became apparent that sending and receiving cryptocurrency is far more complicated than I initially thought. The real challenge was finding a reliable method for automating order fulfillment and processing crypto payments in a way that worked within our country's financial restrictions.
Our team was working on a complex application that required processing multiple types of cryptocurrencies. However, even small transactions can be prohibitively expensive and subject to significant delays when dealing with crypto. This posed a significant challenge for our team, as we needed to find a solution that could handle these complexities without sacrificing our user experience. The goal was to create a system that could handle crypto payments while also complying with local regulations and minimizing transaction costs.
What We Tried First (And Why It Failed)
Our initial approach was to use a popular crypto payment gateway that supported over 100 different cryptocurrencies. We were drawn to this solution because it seemed like it would be easy to implement and would give us access to a wide range of cryptocurrencies. However, we quickly discovered that the fees associated with using this service were astronomical, and the processing times were much longer than we had anticipated. To make matters worse, the gateway's documentation was woefully inadequate, and their support team was unresponsive to our requests for assistance.
We realized that this payment gateway was not suitable for our needs, but we were unclear on what to do next. We began to investigate other options, but they either required us to maintain our own cryptocurrency storage, which we were not equipped to do, or they charged us exorbitant fees for their services. At this point, we were facing a difficult decision: continue using an unreliable and expensive solution or invest in developing our own payment processing system.
The Architecture Decision
After months of research and trial and error, we decided to develop our own custom payment processing system. This decision was not taken lightly, as it required us to invest significant resources into building a system from scratch. However, we were convinced that this was the only way to achieve the level of control and flexibility we needed to process crypto payments efficiently and cost-effectively.
Our solution involved creating a custom implementation of a payment gateway using a combination of APIs and webhooks to connect with various cryptocurrency exchanges. We also implemented a system for automated order fulfillment, which allowed our application to automatically process payments and update the status of orders as necessary. This required us to integrate with multiple external services and write custom code to handle exceptions and errors.
What The Numbers Said After
After launching our custom payment processing system, we were amazed at the results. Our processing fees dropped by over 90%, and our transaction times decreased by an average of 95%. This not only improved the user experience but also allowed us to maintain a higher margin on our sales. Our system was also more reliable than the previous payment gateway, with an uptime of over 99.99% and a mean time to recover of less than 1 minute.
Our decision to develop a custom payment processing system was not without its challenges. However, the benefits far outweighed the costs, and we were able to create a system that met our needs and improved our bottom line.
What I Would Do Differently
In hindsight, I would have explored alternative payment processing solutions more thoroughly before deciding to develop a custom system. I would have also invested more time in researching the technical requirements and feasibility of such a system before committing to the project. This would have allowed us to avoid some of the pitfalls we encountered and get to market faster.
However, I would still recommend developing a custom payment processing system to other engineers facing similar challenges. While it requires significant resources and expertise, the benefits of a custom solution far outweigh the costs. With careful planning and execution, it's possible to create a system that meets your needs and improves your user experience, even in a restricted country.
