Briatore - Italy tax report helper

Briatore takes its name from Flavio Briatore, one of the Italy's most famous tax evader of the recent history.

It represents a tool that can help you fill out your tax report if you live in Italy. To do so, it queries an archive node for each Cosmos chain that you specify and returns:

the amount of tokens that you had on the given date
the value of such tokens at the given date

Usage

Copy the below config somewhere
Install the binary running make install

Run the script with the following command:

briatore report 2021-12-31T23:59:59Z cosmos1...,juno1... --home /path/to/dir/where/config/file/is

NOTE
The reported value is currently returned in Euro (EUR).

  - name: "Osmosis"
