TOP-10 ecosystems in development: Ethereum and Cosmos are growing, L2s are stalling

🕓 Santiment data for August shows where developer energy is sustained and where activity is fading.

📈 Growth:

— Ethereum — 87.1K (+3.48%)

— BNB Chain — 39.4K (+0.52%)

— Cosmos — 28.0K (+3.26%)

📉 Decline:

— Polygon — 34.3K (-11.14%)

— Arbitrum — 28.4K (-13.53%)

— Optimism — 26.8K (-10.53%)

— Avalanche — 24.7K (-10.56%)

— Solana — 21.6K (-3.37%)

— Harmony — 18.8K (-7.44%)

— Polkadot — 15.8K (-11.57%)

📊 The metric accounts for activity in repositories (commits, updates, pull requests, etc.).

💡 Conclusions:

— Ethereum strengthens its leadership: the growth of activity in a mature ecosystem confirms fundamental strength and high developer interest.

— Cosmos also shows momentum — against the backdrop of cross-chain infrastructure development.

— Most L2 solutions (Polygon, Arbitrum, Optimism) have recorded double-digit declines — a worrying signal that team interest may be waning, especially amid token stagnation.

There is now a clear division: foundational and cross-chain networks are strengthening, while some L2s are losing momentum.
