Does this work with coins held in a segwit address on Trezor? Derived by Bip 49.
Trying to do the same but with Ledger. Have not succeded so far. I would compile and sync up a full node but this shit doesn't even exist as source code it seems.
I've built 3 of these on Linux now - United Bitcoin, Super Bitcoin, Bitcoin Diamond. Worth noting that not all the forks necessarily change the datadir or exe names! So when I first tried this, I ended up with two EXEs called bitcoin-qt, obviously with the second overwriting the first. Then after I'd fixed that - there's a configure option to add a prefix to the EXE names - use ./configure --help to find it - one of them popped up saying it was going to use ~/.bitcoin as its datadir. This just seemed like it was going to be trouble in the long run. So I created a separate Unix user for each fork, installed each fork's binaries into somewhere in that user's home folder (e.g., by configuring it with "./configure --prefix=$HOME/usr"), added the user's binaries folder to their PATH, and ran it that way. Then each fork can do whatever it likes, it's all self-contained, and you don't have to remember to run it with --datadir=$HOME/.thatbitcoinfork or something.
This is nothing you couldn't figure out yourself, I'm sure, but maybe it will save you or somebody else the 10 minutes I spent pissing about.
Also a bonus: very easy to just remove all the fork's data when you're done with it.
