In the evolving world of blockchain technology, secure asset management remains a top priority. A paper wallet offers a simple yet effective method for storing cryptocurrencies offline. This guide explains how to create a TRON paper wallet to securely manage TRX and USDT transactions using Python.
What Is a TRON Paper Wallet?
A paper wallet is a physical document that contains your public and private cryptographic keys. The public key functions as your wallet address for receiving funds, while the private key is used to access and spend those funds. Storing these keys offline on paper significantly reduces the risk of online hacking or theft.
TRON is a popular blockchain network known for its low transaction fees and high-speed transactions, making it ideal for transferring assets like TRX and USDT.
Prerequisites for Creating a TRON Paper Wallet
Before you begin, ensure you have Python installed on your system. You will also need the tronpy library, which provides the necessary tools to interact with the TRON blockchain.
Install the package using the following command:
pip install tronpyThe tronpy package is open-source and has been verified for security, with no known vulnerabilities reported.
Step-by-Step Guide to Creating a Paper Wallet
Step 1: Generate a Private Key
To create a new paper wallet, you need to generate a private key. The following Python script accomplishes this:
from tronpy.keys import PrivateKey
wallet = PrivateKey.random()
with open("secret_key.txt", "w") as secret_key_file:
secret_key_file.write(f'{wallet}')
print("Paper wallet created and secret key saved.")Run the script using the command:
python create_wallet.pyThis will generate a private key and save it to a file named secret_key.txt.
Step 2: Securely Store Your Private Key
Open the secret_key.txt file and write down the private key on a piece of paper. Store this paper in a safe and secure location. Never share your private key with anyone, as it provides full access to your funds.
For demonstration purposes, the private key in this example is exposed, but you should always keep yours confidential.
How to Receive TRX or USDT with Your Paper Wallet
Step 1: Retrieve Your Public Address
To receive funds, you need to share your public address. Extract it from your private key using this script:
from tronpy import Tron, keys
secret_key = ''
with open("secret_key.txt", "r") as secret_key_file:
secret_key = secret_key_file.read().strip()
if secret_key:
wallet = keys.PrivateKey(bytes.fromhex(secret_key))
public_address = wallet.public_key.to_base58check_address()
print("Public TRON address:", public_address)Execute the script with:
python get_public_address.pyThe output will be your TRON public address, which looks like this:
TGGFcR1AHg96qMtoJcSYAe7Xmuyg4bqh1WShare this address with anyone who needs to send you TRX or USDT.
Step 2: Activate Your Wallet
Newly created wallets are inactive until they receive their first transaction. Once someone sends TRX or USDT to your address, your wallet will be activated and ready for use.
You can verify transactions and balances using TRONSCAN, a TRON blockchain explorer.
How to Send TRX from Your Paper Wallet
Sending TRX involves a small transaction fee, which is typically lower than on many other blockchains. Ensure you have sufficient TRX to cover both the transfer amount and the fee.
Step 1: Prepare the Script
Use the following Python script to send TRX:
from tronpy import Tron, keys
from tronpy.providers import HTTPProvider
def trx_to_sun(trx_amount):
return int(trx_amount * 1000000)
api_key = "[TRONGRID_API_KEY]" # Replace with your API key
to_address = "TNuTtmTdmdGWKQSnySroeXjyzGh1ZsRau2" # Destination address
amount = trx_to_sun(1.19) # Amount of TRX to send
secret_key = ''
with open("secret_key.txt", "r") as secret_key_file:
secret_key = secret_key_file.read().strip()
tron = Tron(HTTPProvider(api_key=api_key))
if secret_key:
try:
wallet = keys.PrivateKey(bytes.fromhex(secret_key))
from_address = wallet.public_key.to_base58check_address()
txn = (
tron.trx.transfer(from_address, to_address, amount)
.memo("sending TRX")
.build()
.inspect()
.sign(wallet)
.broadcast()
)
txn.wait()
print(txn)
except Exception as e:
exit(f"Submit failed: {e}")Step 2: Configure the Variables
Replace api_key with your own API key from TRON Grid. Change to_address to the recipient’s address and adjust the amount variable as needed.
Step 3: Execute the Script
Run the script with:
python send_trx.pyAfter execution, you will receive a transaction ID (TxID). Use this ID to track your transaction on TRONSCAN.
How to Send USDT from Your Paper Wallet
Transferring USDT on the TRON network involves interacting with the USDT smart contract. Fees may vary based on network conditions and the recipient’s wallet status.
Step 1: Prepare the USDT Transfer Script
Use this Python script to send USDT:
from tronpy import Tron, keys
from tronpy.providers import HTTPProvider
def usdt_to_sun(usdt_amount):
return int(usdt_amount * 1000000)
api_key = "[TRONGRID_API_KEY]" # Replace with your API key
to_address = "TNuTtmTdmdGWKQSnySroeXjyzGh1ZsRau2" # Destination address
amount = usdt_to_sun(7.8) # Amount of USDT to send
secret_key = ''
with open("secret_key.txt", "r") as secret_key_file:
secret_key = secret_key_file.read().strip()
tron = Tron(HTTPProvider(api_key=api_key))
contract_address = 'TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t' # USDT contract address
abi = [{
"outputs": [{"type": "bool"}],
"inputs": [
{"name": "_to", "type": "address"},
{"name": "_value", "type": "uint256"}
],
"name": "transfer",
"stateMutability": "Nonpayable",
"type": "Function"
}]
contract = tron.get_contract(contract_address)
contract.abi = abi
if secret_key:
try:
wallet = keys.PrivateKey(bytes.fromhex(secret_key))
from_address = wallet.public_key.to_base58check_address()
txn = (
contract.functions.transfer(to_address, amount)
.with_owner(from_address)
.fee_limit(50_000_000)
.build()
.inspect()
.sign(wallet)
.broadcast()
)
txn.wait()
print(txn)
except Exception as e:
exit(f"Submit failed: {e}")Step 2: Configure the Variables
Update the api_key, to_address, and amount variables as needed.
Step 3: Run the Script
Execute the script with:
python send_usdt.pyThe script will return a TxID for tracking the transaction on TRONSCAN.
