fundrawtransaction - Bitcoin SV

Example code for the fundrawtransaction json-rpc method. Сomplete guide on how to use fundrawtransaction json-rpc in GetBlock.io Web3 documentation.

Parameters

hexstring - string, required

The hex string of the raw transaction

options - json object, optional

for backward compatibility: passing in a true instead of an object will result in {"includeWatching":true}

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.
