  # Data directory
  dataDir: "."
  # Uncomment if you want SPV to connect to a local node
  #connectDirectlyTo: [localhost]
  # Uncomment if you want SPV to connect to 3 arbitrary nodes/ports
  #connectDirectlyTo: [host1:1111,host1:2222,host1:3333]

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.
