coin_info.py

Central module that extracts information from jsons in defs/ directory. Its most important function is get_all().

cointool.py

Code and data generator. Has the following functions:

• check: runs validations. Currently, that is:

  • schema validity in defs/coins/*.json
  • availability of bitcore/blockbook backends
  • icon format

• coins_json: generates coins.json for use in python-trezor, connect and wallet. By default outputs to current directory.

• coindefs: generates coindefs.json, intended future format for sending coin definitions to Trezor.

• render: for every filename.ext.mako passed (or for all found in directory), renders the Mako template with coin definitions and stores as corresponding filename.ext. This is used to generate code in trezor-mcu and trezor-core.

coins_details.py

Regenerates defs/coins_details.json, which is a catalog of coins for https://trezor.io/coins.

All information is generated from coin definitions in defs/, support info is taken either from support.json, or assumed (see coin_info.support_info()).

If needed, any value can be overriden in coins_details.override.json.

support.py

Support info management. Ensures support.json is in the proper format. Has the following subcommands:

• check: checks validity of support data. Ensures that data is valid, there are no orphaned keys in support.json, no known coins have missing support info, etc.

• show <keyword>: searches coin database, matching key (coin:BTC), name ("Bitcoin") or shortcut / ticker symbol ("BTC"). Displays all coins that match and their support info, if found.

• set <key> [symbol=value]...: updates support info for coin key (coin:BTC, can be found with support.py show). Basic symbols are: trezor1 trezor2 connect webwallet. Anything else is considered a link name: "Electrum=https://electrum.org"
  Allowed values are yes, no, soon, planned, URLs and firmware version numbers. Empty value (trezor1=) clears the respective symbol.
