Solana developers have proposed phasing out durable nonces, the transaction feature attackers used in the $270 million Drift exploit. The change would not activate before May 5, 2027, but custodians and exchanges that rely on offline signing may need to rebuild key workflows.

Solana’s Alpenglow upgrade is now active across both public testing environments, giving application teams more room to prepare before any live-network activation. The change targets about 150 milliseconds for settlement finality, but no mainnet launch date has been announced and the performance goal remains unproven under live-market conditions.

Solana’s Alpenglow upgrade has entered public testnet as developers assess whether the network can sharply reduce transaction finality. The change targets a move from about 13 seconds to 0.15 seconds, a shift that could matter for exchanges, bridges, merchants and other high-speed applications.
