Ethereum stays the main hub for blockchain builders, with over 16,000 new builders becoming a member of the ecosystem between January and September 2025, in line with the Ethereum Basis, citing knowledge from Electrical Capital.
The inflow reinforces Ethereum’s dominance because the world’s most actively developed blockchain, supported by its increasing community of layer-2 options.
Solana Trails Ethereum with 11,500 Builders
Solana ranked second with roughly 11,500 new builders contributing code this 12 months.
Nevertheless, the Solana Basis famous that Electrical Capital’s dataset could also be outdated and undercounts precise figures.
Bitcoin, as compared, attracted round 7,500 new builders over the identical interval.
In line with Electrical Capital’s developer tracker, Ethereum now hosts the most important lively developer base throughout all blockchain ecosystems, with 31,869 lively builders.
Solana follows with 17,708, whereas Bitcoin trails at 11,036. Ethereum’s determine consists of contributors to layer-2 networks reminiscent of Arbitrum, Optimism, and Unichain, as outlined by L2Beat, with out double-counting builders working throughout a number of layers.
Regardless of Ethereum’s lead, Solana’s development over the previous two years has been far stronger.
Full-time Ethereum builders grew by 5.8% year-on-year, whereas Solana recorded a 29.1% enhance in the identical interval and a 61.7% surge over two years, one of many quickest expansions within the trade.

Nonetheless, Solana’s developer rely could also be greater than reported. The inspiration’s head of developer relations, Jacob Creech, stated round 7,800 builders are lacking from the present dataset, urging the group to submit GitHub repositories to enhance Solana’s monitoring.
Some analysts have additionally challenged Electrical Capital’s methodology, arguing that ecosystems utilizing the Ethereum Digital Machine (EVM), reminiscent of Polygon and BNB Chain, must be grouped collectively, since their builders share instruments and programming requirements.
Including to the controversy, Jarrod Watts, head of Australia for layer-2 undertaking Summary, advised that AI-assisted code technology and hackathon initiatives could possibly be inflating the general figures.
“This knowledge doubtless features a tonne of vibe coding slop and hackathon repos which might be by no means touched once more,” he stated.
Latin America’s Builders Flock to Ethereum and Polygon
As reported, builders throughout Latin America are more and more constructing on established blockchains like Ethereum and Polygon as a substitute of making new base-layer protocols, a report from Sherlock Communications discovered.
Ethereum leads regional exercise, accounting for greater than 75% of blockchain transactions, whereas Polygon’s share almost doubled to twenty%.
Builders cited transparency, ease of use, and regulatory readability as key causes for selecting mature ecosystems over newer ones.
In line with Sherlock researcher Luiz Eduardo Abreu Hadad, Latin America’s developer group exhibits “sturdy technical maturity” and a rising deal with fixing real-world issues somewhat than reinventing infrastructure.
On-chain knowledge from 697,000 transactions in international locations together with Brazil, Mexico, Bolivia, and Peru helps this pattern.
Native initiatives like Brazil’s Núclea Chain and RBB, nevertheless, spotlight the area’s potential to construct its personal blockchain infrastructure.
