Solana Proposes New Offline Signing Architecture to Replace Durable Nonces
- The Solana Foundation plans to deprecate durable nonces, which allow transactions to be signed offline, in favor of a new program-derived address (PDA) system.
- Operators will have a six-month migration window to transition assets and permissions under the new architecture, pending the readiness of an approved replacement.
- Two potential replacements are Anza’s Programmatic Signer and Blueshift’s Vector, both of which handle native SOL differently during transactions.
- The migration guide outlines steps for transferring token balances and permissions while legacy durable nonces remain operational.
- Concerns about application access and custody policies were raised by institutional participants during discussions regarding the changes.
This shift aims to simplify validator processes by eliminating complex replay-prevention rules associated with durable nonces, thereby streamlining transaction handling on the network.
With this proposed change, Solana’s operators must adapt their systems within a six-month window while ensuring that all necessary approvals and asset migrations are completed effectively. (Source)
