According to Santiment (@santimentfeed), the top Solana ecosystem projects by development activity in May 2025 are Solana (SOL), Pyth Network (PYTH), Helium (IOT), Helium Mobile (MOBILE), and Wormhole (W). Notably, Helium (IOT) and Helium Mobile (MOBILE) climbed in rankings, indicating increased developer interest and potential future adoption, while Wormhole (W) saw a decline. These shifts highlight changing momentum and development focus within the Solana ecosystem, which can impact short-term price action and liquidity for these tokens. Traders should monitor development trends as strong activity may correlate with higher trading volumes and volatility. Source: Santiment (@santimentfeed, May 7, 2025).
