Ethereum Tops 31,869 Active Developers in 2025, Nearly Double Solana’s Count

Ethereum has extended its lead as the world’s most active blockchain for developers in 2025.

Between January and September, the network added 16,181 new developers, according to data released by the Ethereum Foundation. This figure consolidates Ethereum’s position as the leading hub for blockchain innovation and infrastructure development.

Solana followed with 11,534 new contributors, reflecting the network’s appeal among developers working on decentralized finance (DeFi) and consumer-facing apps.

Moreover, Ethereum also dominates in terms of ongoing engagement. The report shows 31,869 developers actively contributing code to Ethereum, nearly double the 17,708 contributing to Solana.

Together, Ethereum and Solana now account for almost half of all active blockchain developers worldwide. This, in turn, highlights a strong concentration of talent around these two platforms.

Market Trends Reveal Tight ETH–SOL Correlation

The alignment between Ethereum and Solana extends beyond developer activity. Price data analysis shows a correlation coefficient of 0.96 between the two assets. This means that their market movements have closely mirrored each other in recent months.

At the time of the report, Ethereum traded near $3,954, down 4.1% on the day but still above its mid-year levels. Solana hovered around $196, falling slightly more than 3%.

The near-parallel market behavior suggests that investors view both tokens as leading indicators of crypto market risk and sentiment, a sign of their shared standing as central players in the digital asset economy.

Ethereum’s DeFi Dominance Holds, Solana’s Share Expands

Despite Solana’s impressive developer momentum, Ethereum remains the undisputed leader in decentralized finance (DeFi).

According to data from DeFiLlama, the network accounts for 67.5% of the total value locked (TVL) across all DeFi protocols. Meanwhile, Solana’s TVL share stands at 8.7%, indicating a meaningful increase in on-chain activity.

By comparison, other major networks, including Binance Smart Chain (5.1%), Bitcoin (3.12%), and Tron (1.83%), account for smaller portions of the total DeFi market.

The data illustrates how Ethereum continues to anchor DeFi, while Solana’s expanding footprint signals a maturing and increasingly credible challenger.

Outlook: ETH–SOL Rivalry Set to Define Next Blockchain Era

As 2025 progresses, the Ethereum–Solana rivalry is emerging as the principal driver of blockchain platform development.

Ethereum retains its structural advantage through deep liquidity, mature tooling, and a vast developer base. However, Solana is rapidly catching up, driven by its speed, efficiency, and expanding presence in consumer applications and high-performance DeFi.

The ongoing competition will shape innovation, user adoption, and the trajectory of blockchain technology over the next few years.
