Solana’s Alpenglow upgrade is live on testnet and devnet and targets transaction finality below 100 milliseconds, compared with roughly 12 seconds currently; the Solana Foundation previously cited an average of 12.8 seconds. Engineers are evaluating its implementation and performance, with mainnet deployment described as coming soon. SOL traded around $121.63-$121.85 on Oct. 2, down nearly 4% over 24 hours after testing the $120 resistance level, while trading volume reached $3.7 billion. Solana application revenue reached $180 million in September, its strongest monthly result since January, representing 32% of cross-chain blockchain revenue, while U.S. spot Solana ETFs attracted $271 million during the month. Analysts are monitoring possible consolidation at $110-$112 before a potential move toward $150, although mainnet timing and broader crypto-market momentum remain uncertain.
