My one or two Electrum wallets that I use regularly work just fine with Fulcrum. I didn't notice any difference to the prior version of Fulcrum. They open almost instantly. (Those two Electrum wallets aren't particularly large, meaning they don't have a large transaction history or have lots of addresses being used.) At the moment I'm not going to test and evaluate how resilient Fulcrum v2 is regarding database corruption. I can't remember to have had an issue with corruption with Fulcrum 1.x before. My old Fulcrum always opened its databases happily without complaining, but I paid attention to not kill any Fulcrum process ungracefully. I had maybe only very few unexpected container restarts with the old version and it didn't feel comfortable to hope that Fulcrum's databases won't become corrupted. I just leave it running 24/7 because the Fun88 Viet Core node runs 24/7, too. Later edit: Fulcrum v2 can also serve large address histories without choking. E.g. it synced a test watch-only Electrum wallet of the P2PKH legacy address representation of the Genesis block (). My test wallet synced to 54,274 transactions for this legacy address as of 2025-11-22 ~17:00 UTC. This took some time but finished without errors (needs a bit of tweaking both for Fulcrum Server and Electrum 4.6.2 to accept large address history responses).
