Transient Storage

Definition

Transient storage refers to temporary data storage within a blockchain transaction that exists only for the duration of that specific transaction’s execution. Unlike permanent blockchain storage, which records data indefinitely on the ledger, transient storage is cleared once the transaction completes, meaning its contents are not preserved across different blocks. This mechanism is primarily used to optimize gas costs for intermediate computations or temporary state changes that do not require lasting recordkeeping. It provides a more efficient way for smart contracts to handle temporary variables during complex operations.
