  # Uncomment if you want SPV to connect to a local node
  #connectDirectlyTo: [localhost]

Appendix

Known Issues

SPV does not show locked coins (from MainNet launch). If you have a locked-coin balance, SPV will still show as zero.

Running importwallet may take a few minutes to sync the new wallet.
