Solana developers propose abolishing the durable nonce transaction feature

Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
Solana developers have proposed deprecating the durable nonce transaction feature, a mechanism that was exploited in the April attack on the Drift trading protocol, which resulted in losses of at least $270 million. The proposal still requires technical approval and would take effect on mainnet no earlier than May 5, 2027. Durable nonces let signed transactions remain valid indefinitely, allowing custodians and exchanges to sign offline, so affected institutions will need to migrate to alternatives. The Solana Foundation's migration requirements could push back the final deadline. The change matters because it removes a long-standing convenience for institutional signers in favor of tighter transaction validity controls; what to watch next is whether the proposal clears technical review and how custodians and exchanges adapt their signing workflows ahead of the 2027 target.
