Settings.json file

[liorko87]

Hi,

I read the latest bitcoin release notes at https://bitcoincore.org/en/releases/0.21.0/ and they refer to settings.json file.
What is the purpose of this file? is supposed to be alternative to bitcoin.conf?

Can anyone publish a sample for this file?

It is specifically for Bitcoin Core GUI... so if you have multiple wallet files open, they are stored in settings.json, so when you restart, it will automatically re-open the ones you had open when the application was closed.

And if you close a wallet in the GUI, it will be removed from the settings.json, so if you restart, it won't be automatically re-opened.

Also, you can still use -wallet option on commandline or wallet= option in bitcoin.conf

Based from an example in the pull request's comments (bitcoin/pull/15935), it should take some settings from the bitcoin.conf file but in json format.
I don't know if all or which settings will work though.

I've tried some,
example1 (disables wallet function):

Code:

{
    "disablewallet": "1"
  }

example2 (produces legacy addresses in the receive tab):

Code:

{
    "addresstype": "legacy",
    "wallet": [
     "",
     "Wallet_first",
     "wallet_from_v0.xx.dat",
     "Wallet_second"
    ]
   }
