We are officially launched! 🎉
It has been more than six months since this project was started from scratch. The motivation came from a simple observation: there wasn’t a truly accessible, high-quality Rust code provider for cryptocurrency trading available to the public that unifies the APIs and addresses the biggest pain point in crypto trading: enormous fragmentation.
Even among the most popular code providers, most only offered a single exchange — making them prohibitively hard to extend to others. We believed the crypto ecosystem deserved better. When Bitcoin was created by Satoshi Nakamoto, it was built on the principles of openness and transparency. Following that philosophy, we believe open-source crypto connectivity is an important step toward advancing trading infrastructure for everyone.
And here we are: CCRS.
After extensive beta testing, we are confident that our code provides one of the most accurate and efficient approaches to API integration on the most important cryptocurrency exchanges available today.
Why a new library?
While many people may ask why we need another crypto connectivity library when there are already popular open-sourced C++ wrappers (like CCAPI) available, our own story reveals why this was necessary. We started with C++ for developing our own high-frequency trading applications, but we encountered a few painstaking pain points:
Memory issues: Sporadic segmentation faults were the most time-consuming bugs we had to chase. In C++, it is incredibly hard to trace back the exact line of code causing random crashes. The amount of effort we spent on it was simply huge.Dependency management: Unlike many other languages, C++ doesn’t have a de-facto dependency management system like npm, pip, or cargo. It isn’t uncommon for certain dependencies to have to be built and version-tracked manually (for example, the Intel Decimal Floating-Point Library).The Header Dilemma: C++ code forces you to switch your head between header and implementation files. For a large HFT project, that is a lot of context jumping. On the other hand, making it “header-only” makes the compilation process very slow (like the Boost or RapidJson libraries).
In Rust, none of these is an issue.
You can verify online that nowadays, many job openings in the HFT industry — especially in crypto and for greenfield projects — choose Rust rather than C++ as the target language. We truly think that 2026 has come to a tipping point where the advantage of using Rust to replace legacy C++ systems outweighs the disadvantage.
We are on a strong path toward open-sourcing more of our codebase so that traders and developers no longer have to reinvent the wheel. But for now, take a look at CCRS and enjoy!
We’d love to hear your feedback, requests, and suggestions at our Telegram group. 😃
