Solana’s Alpenglow Goes Live on Devnet Ahead of Mainnet Migration

Anza has deployed the Alpenglow upgrade to Solana's developer network and is soliciting participation from application developers to run tests on programs and integrations. The announcement positions this testing window as a chance for ecosystem actors to exercise their code against the new behavior before any change is applied to the live network.

A central element of Alpenglow is moving validator voting off-chain. That change alters where and how validators record and communicate voting information, representing a modification to an element of the network's operational workflow.

While the upgrade is active on devnet for testing purposes, activation on Solana's mainnet has not yet been triggered. The current phase therefore remains focused on developer and integration testing rather than a full network migration.

Anza's outreach to developers underscores the project's reliance on community testing to identify integration issues and ensure applications behave correctly under the modified voting approach. Any subsequent timetable or conditions for mainnet activation were not provided in the material.
