Solana Developers Propose Scrapping Durable Nonce Transaction Feature

On November 9 that, according to CoinDesk, Solana developers have proposed eliminating the persistent nonce transaction feature, a mechanism previously used in the April attack on the trading protocol Drift that resulted in losses of at least $270 million. The proposal still requires technical approval and will take effect on the mainnet as early as May 5, 2027.

Persistent nonces allow signed transactions to remain valid for extended periods, enabling custody institutions and exchanges to perform offline signing. The report indicates that relevant institutions need to migrate to alternative solutions; migration requirements imposed by the Solana Foundation may delay the final deadline.
