--- entry: "Transaction Unlock Time" terms: ["unlock-time", "tempo-di-sblocco"] summary: "a special transaction where the recipient can only spend the funds after a future date, as set by the sender" --- {% include untranslated.html %} ### The Basics A special transaction where the recipient can only spend the funds after a future date, as set by the sender. Unlock time allows you to send a transaction to someone, such that they can not spend it until after a certain number of blocks, or until a certain time. Note that this works differently than Bitcoin's [nLockTime](https://en.bitcoin.it/wiki/NLockTime), in which the transaction is not valid until the given time.
