+tagline: A fast and nimble Electrum Server
+description: >-
+  Run your personal Electrum server and connect your Electrum-compatible wallet,
+  including BitBoxApp, BlueWallet, Electrum Wallet (Android and Desktop), Nunchuk 
+  (Desktop), Phoenix, and Sparrow Wallet to it instead of using a third-party
+  Electrum server.
+  
+  
+  Powered by Fulcrum from Calin Culianu
+  
+    
+  ⚠️ Fulcrum does not yet automatically integrate with other apps in the Bitcoin ecosystem on Umbrel. However, in a future umbrelOS update, users will be able to choose which Electrum Server app they want to use to connect with other apps.
