**Ethereum Adds Over 16,000 New Developers in 2025, Maintaining Lead in Blockchain Development**

Between January and September 2025, Ethereum attracted more than 16,000 new developers, reinforcing its position as the most actively developed blockchain network worldwide. According to the Ethereum Foundation and data from Electric Capital’s developer tracker, Ethereum now boasts a total of 31,869 active developers across its core network and layer-2 solutions such as Arbitrum, Optimism, and Unichain.

### Ethereum Remains the Leading Blockchain for Developer Activity

Ethereum leads the blockchain space with the largest developer ecosystem, encompassing contributors working on both the main network and various layer-2 platforms. The reported developer count excludes individuals contributing across multiple layers to avoid double-counting.

Year-over-year, Ethereum’s developer base grew by 5.8%, maintaining a steady upward trajectory. Key factors driving this growth include Ethereum’s consistent ecosystem, regulatory clarity, transparency, and ease of integration, which appeal to developers compared to newer blockchains.

The Ethereum Foundation credits its active community and robust tooling infrastructure for attracting thousands of new developers in 2025. Notably, Ethereum dominates developer activity in Latin America, accounting for over 75% of blockchain transactions in the region — a trend reflective of a broader global migration toward Ethereum’s stable ecosystem.

### Solana Experiences Strong Developer Growth Amid Data Concerns

Solana ranked second in developer growth, welcoming approximately 11,500 new developers during the same period. By September 2025, Solana’s active developer community reached 17,708 — marking a 29.1% increase from the previous year and a 61.7% growth over the past two years.

Despite these impressive numbers, the Solana Foundation has contested the dataset’s accuracy, stating that around 7,800 developers may be missing from Electric Capital’s tracking. Jacob Creech from Solana urged the community to update GitHub repository submissions to enhance data accuracy.

Solana’s allure stems from its fast execution times and scalable infrastructure, which have spurred faster developer activity growth compared to Ethereum. However, tracking methods remain under review to better capture the full scope of Solana’s developer base.

### Bitcoin’s Developer Growth Remains Steady But Slower

Bitcoin attracted roughly 7,500 new developers between January and September 2025, bringing its total to 11,036 active developers. This places Bitcoin third among the largest blockchain ecosystems by developer count.

While Bitcoin continues to see steady development activity, its growth pace lags behind more versatile platforms like Ethereum and Solana. Bitcoin’s limited smart contract capabilities restrict broader innovation, leading many developers to favor ecosystems offering programmable features, such as Ethereum’s EVM-compatible infrastructure.

Overall, the first nine months of 2025 underscore Ethereum’s dominance in developer engagement and ecosystem growth, while Solana shows rapid gains albeit with some data reporting challenges. Bitcoin remains a foundational player with steady but comparatively slower developer expansion.
