decoderawtransaction

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

Argument #1 - hexstring

Type: string, required

The transaction hex string

Argument #2 - iswitness

Type: 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.
