# decoderawtransaction

Return a JSON object representing the serialized, hex-encoded transaction.

This method will use `10` [Compute Units](/v1/about/billing.md).

***

## **Reference:** [**Here**](https://developer.bitcoin.org/reference/rpc/decoderawtransaction.html)

## **Parameters**

**`hexstring`** - string, required

The transaction hex string

**`iswitness`** - boolean, optional, default=depends on heuristic tests

**Whether the transaction hex is a serialized witness transaction.**

If `iswitness` is not present, heuristic tests will be used in decoding. If true, only witness deserialization will be tried. If false, only non-witness deserialization will be tried. This boolean should reflect whether the transaction has inputs (e.g. fully valid, or on-chain transactions), if known by the caller.
