Hi guys,

@craigraw answered me. Once Sparrow is launched, you can export the config.ini lines from File > Export wallet.
Then, you add the right lines into your config.ini EPS file.

The problem was about the watch-only address in Bitcoin Core: there were 13 addresses to look at, and only 1 in Bitcoin Core.

Gonna make a video tutorial to help people about it.


Have a beautiful day !
