Installation

To install CNGnManager and its dependencies, run:

pip install cngn-manager

Usage

First, import the CNGnManager class using it namespace WrappedCBDC\CNGNManager: and all necessary constants.

from cngn_manager import CNGnManager, Network, ProviderType

Then, create an instance of CNGnManager with your secrets:

import os

api_key = "cngn_live_sk**********"
encryption_key = "yourencryptionkey"
ssh_private_key = """-----BEGIN OPENSSH PRIVATE KEY-----
your ssh key
-----END OPENSSH PRIVATE KEY-----"""

# NOTE: You can also get your private key from a file using
# ssh_private_key = os.open("/path/to/sshkey.key").read()

manager = CNGnManager(api_key, ssh_private_key, encryption_key)
# Example: Get balance
balance = manager.get_balance()
print(balance)

Available Methods

Get Balance

balance = manager.get_balance()
print(balance)

Get Transaction History

transactions = manager.get_transaction_history()
print(transactions)

Swap Between Chains

swap_params = {
    "amount": 100,
    "address": "0x1234...",
    "network": Network.BSC
}

swap_result = manager.swap_between_chains(swap_params)
print(swap_result)

Deposit for Redemption

deposit_params = {
    "amount": 1000,
    "bank": "Example Bank",
    "accountNumber": "1234567890"
}

deposit_result = manager.deposit_for_redemption(deposit_params)
print(deposit_result)

Create Virtual Account

mint_params = {
    "provider": ProviderType.KORAPAY
}

virtual_account = manager.create_virtual_account(mint_params)
print(virtual_account)

Whitelist Address

whitelist_params = {
    "bscAddress": "0x1234...",
    "bankName": "Example Bank",
    "bankAccountNumber": "1234567890"
}

whitelist_result = manager.whitelist_address(whitelist_params)
print(whitelist_result)

Testing

This project uses Jest for testing. To run the tests, follow these steps:

1. Run the test command:

python3 -m unittest discover tests

This will run all tests in the tests directory.

Test Structure

The tests are located in the tests directory. They cover various aspects of the CNGnManager class, including:

• API calls for different endpoints (GET and POST requests)
• Encryption and decryption of data
• Error handling for various scenarios

Error Handling

The library uses a custom error handling mechanism. All API errors are caught and thrown as Error objects with descriptive messages.

Types

The library includes python definitions for all parameters and return types. Please refer to the type definitions in the source code for more details.

Security

This library uses AES encryption for request payloads and Ed25519 decryption for response data. Ensure that your encryptionKey and privateKey are kept secure.

Contributing

Contributions, issues, and feature requests are welcome. Feel free to check issues page if you want to contribute.

Support

If you have any questions or need help using the library, please open an issue in the GitHub repository.
