Fulcrum VS HWI

Fulcrum. Fulcrum requires more resources than romanz/electrs but it can still run on a Raspberry Pi, and it handles heavy queries much more efficiently. If you're having issues with romanz/electrs, Fulcrum is worth a try.

https://github.com/cculianu/Fulcrum (Electrum server, most wallets rely on it to find UTXOs belonging to addresses)

I am not familiar with EPS so the only thing I am going to suggest is to try Fulcrum which is another electrum server implementation and it's super fast. After setting it up, I let it sync and build the database (it took 8 hours) and now I can connect both Sparrow Wallet and BlueWallet to it both via Tor on port 50001 and SSL on port 50002 with the self-signed certificate I created.

How will you be using the node? FYI for a lot of use cases, an SPV friendly indexer like Fulcrum (high performance version of Electrum) will work, for example through the JS library Electrum Cash. There is also the massively powerful but also heavy ChainGraph. There is also Bitcoin Verde node which uses a SQL database for storage which is nice if you want that. Etc. But yeah, sucks about BCHD for now.

That's you running for example ElectrumX or Fulcrum, or any other Electrum-server implementation on top of your bitcoind.

Or you can run an electrum server on top of bitcoin core, which is what I do. I use Fulcrum, because it's really easy to install. Then you can point your Electrum wallet (Android or PC) or Sparrow (PC) or BlueWallet (iOS or Android) to your own electrum server.

You are asking about whether Trezor Suite supports PSBT format, and the answer is no. There's however several options that do support PSBT and work with Trezor, such as HWI, Electrum, and presumably also Sparrow Wallet itself.

If your OS is Linux you need to create a set of udev rules for the hardware wallet to be reachable. The instructions can be found here: https://github.com/bitcoin-core/HWI/blob/master/hwilib/udev/README.md

Options are HWI or Electrum or some hardware devices' software apps support SPV HWI: https://github.com/bitcoin-core/HWI Multiple choices of Electrum server: https://blog.keys.casa/electrum-server-performance-report-2022/

A partial support was already developed by Andrew Chow in https://github.com/bitcoin-core/HWI (merged just a few days ago), which will probably be released soon; HWI is used by bitcoin-core and several other software wallets, so that release will already bring an improved support − but support for policy registration will be partial and therefore a bit inconvenient to use.

yes, but you need to use this tool https://github.com/bitcoin-core/HWI

This is usually done with HWI. Some people have forked the code and used it in a nice skinned GUI, but I can't recall the name. Maybe someone can post it here. I did it all through command-line and did a fairly detailed writeup. It's pretty easy, just hard to guess the skillset of the reader.

Yes I've used the official Ledger Live software and tried multiple cables, including 2 different Ledger cables. I just updated the udev rules a la https://github.com/bitcoin-core/HWI/tree/master/hwilib/udev but still nothing. I can see everything in Ledger Live, can activate my Manager, etc, just I can't send anything from Wasabi anymore.
