I mean after it is broadcast someone can can auto RBF it to their address. It has happened before.

Using something like Slipstream would be the ideal way to broadcast.

A high end consumer GPU could probably crack it in a few seconds using an optimized Pollard's Kangaroo implementation once the public key is revealed.

Yes, that is my understanding too.

Thinking about making the auto boardcast optional/opt-out. Then the user can decide how to boardcast the TX.

Makes the app less hands-off, unfortunately.
