Solana developers have proposed removing the durable nonce transaction feature, according to a November 9, 2026, Jinse Finance report citing CoinDesk. The proposal still requires technical approval; the earliest possible mainnet effective date is May 5, 2027.
Durable nonces allow signed transactions to remain valid for an extended period, supporting offline signing by custodians and exchanges. Those institutions would need to move to alternatives if the feature is removed.
The mechanism was also used in the April attack on trading protocol Drift, which caused losses of at least $270 million, according to the report. The report does not establish that the feature itself was the root cause of the attack.
The transition schedule is not final. Solana Foundation migration requirements could push back the deadline.
