Presigned Transactions

Definition ∞ Presigned Transactions are fully formed, cryptographically signed blockchain transactions that are prepared in advance but not immediately broadcast to the network. These transactions contain all necessary parameters and are valid for execution once they are submitted. They enable delayed or conditional execution without requiring the original signer to be online at the precise moment of submission.
Context ∞ Presigned transactions prove valuable in various advanced blockchain applications, including gasless transactions, account abstraction, and sophisticated automated protocol interactions. News often covers their utility in enhancing user experience and enabling more complex decentralized application logic. It is important to consider the security implications involved in managing such signed data.
