# ConfirmTransaction

Confirms a saved transaction request and prepares it for execution by updating its status from **SAVED** to **READY**.

**Process flow:**

1. Validates the saved transaction request parameters
2. Calculates and populates gas fees, nonce, and other blockchain-specific fields
3. Updates status to **READY**, making it available for execution
4. Sets expiration time for the confirmed transaction

**When to use:**

* After creating a transaction request with `status:\ "SAVED"`
* Before calling the execute endpoint to complete the transaction
* When you're ready to finalize gas calculations and network parameters

**Important notes:**

* Only works with transaction requests in **SAVED** status
* Gas fields will be auto-populated based on current network conditions
* The confirmed transaction will have an expiration time after which it cannot be executed
