Solana proposes retiring durable nonces after Drift hack

Solana developers have proposed retiring 'durable nonces,' a feature that kept signed transactions valid indefinitely and was exploited to steal $270 million from the Drift trading protocol in April. The draft proposal, SIMD-0723, would not take effect before May 5, 2027, giving custodians and exchanges that rely on offline signing time to migrate. While the feature accounted for only 3% of Solana's traffic in June, it generated 30% of priority fees, driven primarily by a small number of high-volume accounts. Open article →
