pykomodefi 0.2.6

KomoDeFi Framework wrapper for Python

pykomodefi is a simple wrapper around Komodo Platform's DeFi Framework.

Installation

pip install pykomodefi

Usage

Configuration:

The configuration file can be passed as a parameter to the KomoDeFi_API class constructor:

   >>> import pykomodefi
   >>> dexapi = pykomodefi.KomoDeFi_API(config="/path/to/MM2.json")

If not set, the default configuration file path is MM2.json in the current folder, or ~/.kdf/MM2.json. It can be set to a different file later:

   >>> import pykomodefi
   >>> dexapi = pykomodefi.KomoDeFi_API()
   >>> dexapi.set_config = "/path/to/MM2.json"

Simple RPC call:

   >>> resp = dexapi.rpc("get_enabled_coins")
   >>> resp
   {
      'result': [
         {
            'ticker': 'KMD',
            'address': 'RMC1cWXngQf2117apEKoLh3x27NoG88yzd'
         },
         {
            'ticker': 'LTC',
            'address': 'LQyzwFtf8HU7VYQMhop5bv857uMao4jnKX'
         }
      ]
   }

RPC call with parameters:

   >>> params = {"coin": "KMD"}
   >>> resp = dexapi.rpc("my_balance", params)
   >>> resp
   {
      'coin': 'KMD',
      'balance': '20',
      'unspendable_balance': '0',
      'address': 'RMC1cWXngQf2117apEKoLh3x27NoG88yzd'
   }

v2 RPC call:

   >>> resp = dexapi.rpc("get_public_key", v2=True)
   >>> resp
   {
      'mmrpc': '2.0',
      'result': {
         'public_key': '0371792f7a6846a0da28f3422501927ae103355c02750bc4c4d8430375329a09ac'
      },
      'id': None
   }

The following methods are available as properties of the KomoDeFi_API class. These methods do not require any input parameters:

   >>> dexapi.version
   '1.0.7-beta_afe2e08'

   >>> dexapi.pubkey

Some configuration params from within MM2.json are also available as properties:

>>> dexapi.netid
8762
>>> dexapi.rpcip
127.0.0.1
>>> dexapi.rpcport
7783
>>> dexapi.db_dir
/path/to/DB

Building locally

• Run poetry build
• Run pipx install --spec $(pwd)/dist/pykomodefi-0.2.6.tar.gz pykomodefi --include-deps --force (change version number accordingly)

Running tests

Prerequisites:

• Install dependencies: poetry install
• Set up test configuration by either:
  • Creating tests/.env file with: MM2_JSON_PATH=tests/MM2.json
  • OR copying test config to project root: cp tests/MM2.json .

Run tests:

# Run all tests with coverage
poetry run pytest tests/ -v

# Run tests with verbose output
poetry run pytest tests/ -vv

# Run with coverage report
poetry run pytest tests/ --cov=pykomodefi --cov-report=html

Note: Tests will show connection errors if the KomoDeFi Framework (MM2) is not running. This is expected behavior - the package correctly handles and reports connection failures. To run tests against a live MM2 instance, ensure MM2 is running on 127.0.0.1:7783 before running the tests.
