Solana’s offline-signing proposal would keep approvals valid after failed transactions
Solana is considering replacing durable nonces with signer programs that verify cold-wallet approvals and execute transactions through program-derived addresses. Cold keys would still authorize actions, while online relayers submit them and pay fees. Migration would require moving assets or specific authorities, and applications must support actions delivered through cross-program calls. The proposed designs differ in how tightly signatures bind surrounding instructions and how they handle SOL, but both may allow failed approvals to be retried unless they expire or are revoked. The Foundation has set no removal date and has not selected between Programmatic Signer and Vector. Its conditional migration window is about six months after a suitable replacement is audited and live on mainnet; current tooling and deployment readiness remain incomplete.
