Create User instance with meta mask wallets public address

• To create a user and wallet instance based on public address of metamask wallet, send a POST request to the base url for the application. Using the above example it would be metamask/

• By default the url will expect the following data:

  {
      user: {
          <USER_MODEL_REQUIRED_FIELDS>
  
      }
      public_address: <public_address>
  }

• Example using the django default user model:

  {
      user: {
          username: Example,
          email: example@gmail.com
      }
      public_address: examplepublicaddress123
  }

• You dont need to send a password. An unsable password is set for the user model since we wont be needing it for validation

• An automatic nonce is generated for the user on creation

Retrieve Nonce for Created User

• To retreive the nonce of an instance send a GET request to the base url for the application with public_address as a path param. Using the above example it would be metamask/<int: public_address>

• This will fetch the wallet data as per serializer

Login User to get JWT Token

• To login a user send a POST request to the baseurl + login/<int:public_address> post fix. Using the above example it would be metamask/login/<int: public_address>

• By default the url will expect the following data:

  {
      signature : <signed by meta mask>
  }

• This will reqturn an JWT token in reponse which can be used for authentication.

• The rest is same as using djangorestframework-simplejwt to manage JWT tokens and you can refer to their `documentation <https://django-rest-framework-simplejwt.readthedocs.io/en/latest/>`_ for configurationa and customizations

Settings

You can provide MetaMaskAuth settings like this:

DEFAULTS = {
    "UPDATE_LAST_LOGIN": False,
    "NONCE_LEN": 24,
    "VALIDATION_SERIALIZER": "metaMaskAuth.serializers.WalletTokenObtainSerializer",
    "WALLET_AUTHENTICATION_SERIALIZER": "metaMaskAuth.serializers.WalletAuthSerializer",
    "USE_SLIDING_TOKEN": False,
}

• UPDATE_LAST_LOGIN

  • A boolean value, which is used to update last login of user on login

• NONCE_LEN

  • An int value, which controls the length of nonce generated. Default is 24

• VALIDATION_SERIALIZER

  • This is a string import, for the serializer which contains the logic for validation. You can override this serializer to customize the validation method. This would then be inherited by TokenObtainPairSerializer aswell as TokenObtainSlidingSerializer.

• USE_SLIDING_TOKEN

  • A boolean value, used to set whether to use sliding token or not.
