Ethereum and Solana: Recent Gains and Upcoming Changes In September
Ethereum (ETH) and Solana (SOL) both rose last week, up 10.2% and 15.5% respectively, but are still down year-to-date. Solana's Alpenglow upgrade, set for September 28, aims to reduce transaction finality time and improve network reliability. Ethereum's Glamsterdam upgrade has been delayed to Q4 2024. Solana ETFs saw 12 weeks of inflows, while Ethereum funds had $140M outflows in September.
