I am making an attempt to create a P2SWH tackle with a script that locks the cash for a while. After which I wish to spend these cash from that tackle.
I’ve learn quite a bit, a number of the most related:
These are the steps I’ve taken. The place am I going fallacious?
- Create an tackle to be locked

Wanting on the decoded hex of this incomplete txn, I see there is no such thing as a witness knowledge. Am I alleged to be supplying that? I am in all probability getting one thing fallacious alongside the best way, however unsure what.
