This repository enables you to check the balance of XDC and XRC20 tokens and transfer funds from multiple wallets to a single wallet.

1. Owning SRX nodes or PLI nodes allows you to receive monthly rewards. However, it's not easy to check if the rewards have been credited when you have multiple nodes. Therefore, we consolidate the XDC, SRX, and PLI balances of each wallet and output them in a csv file.
2. Also, we want to consolidate the rewards received from multiple wallets into one wallet. Doing so reduces the balance of the wallets to zero, making it easier to understand the next rewards received and simplifies the manual transfers when selling on exchanges.

• While it is possible to check the balance using just a wallet address, a private key is required for transfers. However, managing private keys is extremely important, so we use a .env file, further encrypted and protected by a password.

This Node.js script is designed to securely protect important configuration files (.env). The script operates in the following manner:

1. Encryption of the .env file:

   • The aes-256-cbc algorithm is used, employing randomly generated keys and an Initialization Vector (IV) to encrypt the .env file.
   • The encrypted data is saved as .env.encrypted.

2. Secure storage of key information:

   • The keys and IV used to encrypt the .env file are encrypted again for additional protection.
   • A new key and IV are generated based on the password entered by the user, and these are used to re-encrypt the key information (SECRET_KEY and IV) using the aes-256-cbc algorithm.
   • The re-encrypted data is stored in keys.json.

• Passwords are safely processed using the robust key derivation function crypto.scryptSync, although it is recommended to use random salt in actual usage.
• The key information within the keys.json file is also encrypted, ensuring that in the event of a data breach, key information is not directly exposed.

This script is particularly useful for protecting files containing sensitive information such as environment variables and API keys. The double encryption adds an extra layer of security, further enhancing data protection.

cd && git clone https://github.com/11ppm/XDC-Token-Manager
cd ~/XDC-Token-Manager
chmod +x run.sh

• You need to have Node.js and npm installed on Ubuntu. To check this, execute the following commands in the terminal:
• Plugin nodes have them installed, SRX nodes do not. Either way, use a test machine rather than a production machine.

node -v
npm -v

• If Node.js is not installed, run the following command:

sudo apt update && sudo apt install nodejs npm -y 

• Install three npm packages: xdc3, dotenv, and readline-sync.

npm install xdc3 dotenv readline-sync

• xdc3: A JavaScript library for interacting with the Ethereum network
• dotenv: A library for managing environment variables in Node.js applications
• readline-sync: A library for handling interactive user input in Node.js applications

By installing these, you can utilize their respective functionalities.

• Enter the private keys for your XDC Wallet. For now, they are written from PRIVATE_KEY_1 to PRIVATE_KEY_10. You can increase or decrease the number as needed. If no private keys are entered, they will be ignored.
• Enter the recipient wallet address to which you want to send funds from multiple wallets at YOUR_RECIPIENT_WALLET_ADDRESS. The address should start with 'xdc'. Don't forget the recipient.
• If you plan to use the created .env file in the future, store it securely on your local PC.

./run.sh

• If you're running it for the first time, always choose option 1 first. This will encrypt your .env. As a result, an encrypted .env.encrypted file and a keys.json necessary for decryption are created, and the .env is deleted. Without .env.encrypted and keys.json, decryption is not possible.

• You need to edit the .env beforehand
• Enter an arbitrary password twice. Don't forget the password you enter. Never share your private keys or password with others, and keep them in a safe place.
• The .env file will be deleted

• Output in a csv file

• Output in a csv file

• Sent to the YOUR_RECIPIENT_WALLET_ADDRESS in your .env. If forgotten, run 6. to decrypt the .env

• Sent to the YOUR_RECIPIENT_WALLET_ADDRESS in your .env. If forgotten, run 6. to decrypt the .env

• Without .env.encrypted and keys.json, decryption is not possible. Backup these two to restore the .env.

Some may be afraid to run it on the Mainnet. Although it's just for peace of mind, we have prepared a single code for Apothem.

node apothem_getBalances_Pli.js

Get test XDC and PLI from the following:

• Apothem XDC : https://faucet.blocksscan.io/
• Apothem PLI : https://faucet.goplugin.co/
