This may take some timeElectrum must first fully index the blockchain and compact its database before you can connect to it with your signing devices. This can take up to ~1.5 - 4 days or more, depending on the hardware.
We will set up an Electrum server for use with your Bitcoin software or hardware signing device.

This gives you security, privacy and eliminates the need to trust a third party to verify transactions.
Bitcoin client on the MicroBolt itself is not meant to hold funds.
One possibility to use Bitcoin client with your Bitcoin signing devices is to use an Electrum server as middleware. It imports data from Bitcoin client and provides it to signing software supporting the Electrum protocol. Desktop signing apps like Sparrow, the BitBoxApp, Electrum or Specter Desktop that support signing devices can then be used with your own sovereign Bitcoin node.
