Solana developers have proposed removing durable nonce transactions, a feature that allows signed transactions to remain valid for extended periods and supports offline signing by custodians and exchanges, according to a November 9, 2026, Jinse Finance report citing CoinDesk.
For institutions using the feature, its removal would require migration to an alternative. The proposal still needs technical approval and could take effect on mainnet no earlier than May 5, 2027. Solana Foundation migration requirements could push the final deadline back.
The report also said the mechanism was used in the April attack on trading protocol Drift, which resulted in losses of at least $270 million. That reported use does not, by itself, establish that the feature caused the attack.
