Cryptocurrency developers continue to drive innovation, with their activity on GitHub providing a key barometer of technical progress across the industry.
A recent report highlighting developer interest as of June 2025 shows Cardano (ADA) and Ethereum (ETH) topping the list for their contributions and ecosystem scale.
Cardano’s Core Strength and Ecosystem Trends
Cardano secured the leading position in core developer activity over the past week, demonstrating a significant margin. A total of 53 developers contributed to Cardano’s 550 core repositories, making 355 core commits. These figures solidly placed Cardano at the forefront of weekly core development. While monthly core commits saw a slight increase of 0.3%, the number of core developers decreased by 9.8% over the same period.
Despite its strong core performance, Cardano’s broader ecosystem-wide activity showed a downward trend. Commits across its ecosystem decreased by 25.26% to 1,173, and the number of developers contributing to the ecosystem fell by 19.92% to 176 compared to previous months.
Ethereum’s Expansive Ecosystem and Developer Engagement
Ethereum, while not leading in direct core contributions, stands out due to the sheer scale of its ecosystem. This week, a remarkable 1,567 projects operating on the Ethereum network received support from 1,572 developers, who collectively made 24,144 commits to these projects. However, even with its extensive network, Ethereum’s ecosystem experienced a decline, with the number of developers decreasing by 24.68% and commits falling by 18.04%.
