CryptoPulse.CoinDesk reported on September 26, 2026, that Solana’s Alpenglow upgrade is running on both public test networks. Application teams can reportedly use the environments to check their software before any switch on the live blockchain. SOL was up 16.93% over 24 hours, but the supplied information does not confirm a connection between that move and the upgrade.
According to the supplied report, Alpenglow has reached both Solana public test networks. These test environments are intended to let application teams check their software ahead of any future change to Solana’s live blockchain.
Public-network testing can give developers an opportunity to identify compatibility issues before a protocol change reaches the live chain. The information provided does not confirm the upgrade’s final timing, performance, or impact on applications.
SOL was trading at $121.90, up 16.67% over one hour and 16.93% over 24 hours. The available data does not establish that the move was caused by the Alpenglow test-network update.
Watch for technical test results, developer feedback, a confirmed mainnet activation schedule, and evidence that applications remain compatible during the transition.
