• Private keys must be provided if wallet doesn't contain them.

• Returns complete: false if more signatures are needed.

• Sighash types: ALL, NONE, SINGLE (with optional ANYONECANPAY).

Parameters

Parameter	Type	Required	Description

prevtxs	array	No	Array of previous transaction outputs.
privkeys	array	No	Array of private keys for signing.
sighashtype	string	No	Signature hash type (default: ALL).
