Installation

To install CNGnManager and its dependencies, run:

pip install cngn-manager

Usage

First, import the CNGnManager WalletManager class using and all necessary constants.

from cngn_manager import CNGnManager, WalletManager, Network, ProviderType, AssetType

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)

Networks

The library supports multiple blockchain networks:

• Network.bsc - Binance Smart Chain
• Network.atc - Asset Chain
• Network.xbn - Bantu Chain
• Network.eth - Ethereum
• Network.matic - Polygon (Matic)
• Network.trx - Tron
• Network.base - Base

Available Methods

cNGNManager 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,
    "shouldSaveAddress": True
}

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

Redeem Asset

deposit_params = {
    "amount": 1000,
    "bankCode": "123",
    "accountNumber": "1234567890",
    "saveDetails": True
}

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

NOTE: to get bank codes please use the getBanks method to fetch the list of banks and ther codes

Create Virtual Account

mint_params = {
    "provider": ProviderType.KORAPAY
}

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

NOTE: before creating the virtual account you need to have updated your BVN on the dashboard

Generate Wallet Address

wallet_address = manager.generate_wallet_address(Network.BSC)
print(wallet_address)

Update Business

Address Options: "xbnAddress": "string"; "bscAddress": "string"; "atcAddress": "string"; "polygonAddress": "string"; "ethAddress": "string"; "tronAddress": "string"; "baseAddress": "string"; "bantuUserId": "string";

updateData  = {
    "walletAddress": {
        "bscAddress": "0x1234...",
        #other chain addresses...
    },
    "bankDetails": {
        "bankName": 'Test Bank',
        "bankAccountName": 'Test Account',
        "bankAccountNumber": '1234567890'
    }
}

updateResult = manager.update_external_accounts(updateData)
print(updateResult)

Get banks

banklist = manager.get_banks(updateData)
print(banklist)

WalletManager Methods

Generate Wallet Address

    wallet = WalletManager.generate_wallet_address(Network.bsc);

Response format:

 {
    "mnemonic" : "string";
    "address": "string";
    "network": Network;
    "privateKey": "string";
}

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.

Constants

The library includes python constant classes for all parameters:

• Network - token network
• AssetType - Asset constants
• ProviderType - provider constants

Security

• Uses AES encryption for request data
• Implements Ed25519 decryption for responses
• Requires secure storage of API credentials
