Solana developers move to retire feature tied to $270M Drift hack

Solana developers are moving to retire the Durable Nonce feature that was exploited in the $270 million Drift hack in April, CoinDesk reported. The feature allows signed transactions to be executed without an expiration deadline, and the Drift hackers are known to have used it to hold pre-approved transactions for more than a week before executing them. According to improvement proposal SIMD-0723 submitted by Gabe Rodriguez of Solana core developer Anza, the change could take effect after May 5, 2027.
