PEPECOIN class to interact with pepecoin blockchain in a easy way

This repository is an independent project and is not affiliated with the official Pepecoin team (Yet this project uses the same pepecoin). For the official Pepecoin repository, please visit Pepecoin Core.

Pepecoin Python Client [₱]

Pepecoin Python Client is a python client library for easily interacting with a Pepecoin node (via RPC) and developing cool applications.

If you want to check out a "Pepecoin Payment Gateway" example, check out this link: Pepecoin FastAPI Payment Gateway.

The Pepecoin class provides a simplified interface for wallet management, address generation, balance checking, payment verification, node connection checking, wallet locking/unlocking, and mass transferring funds.

---

Features

• Simplified RPC Connection: Easily connect to a Pepecoin node using RPC.
• Wallet Management: Create, encrypt, lock, and unlock wallets.
• Address Generation: Generate new Pepecoin addresses with optional labels.
• Balance Checking: Check the balance of wallets.
• Payment Verification: Verify if payments have been received at specific addresses.
• Mass Transfer: Transfer funds from multiple wallets to a single address.
• Node Connection Checking: Verify if the Pepecoin node is connected and reachable.

---

Installation

Install the package via pip:

pip install pepecoin

---

Getting Started

Prerequisites

• Automatic Setup: If you haven't gone through the official setup process, you can run the following command (comes with pip install pepecoin ) to start the installation automatically:

  pepecoin-setup
  

  This command will execute a bash script included in the Pepecoin package that follows the steps in the official Pepecoin installation documentation. Feel free to inspect the script before running it. it does these steps:
  1. Prompts you for rpc_user and rpc_password you wanna use. 2. Download compiled binaries 3. Create pepecoin.conf 4. Add Pepecoin binaries to PATH 5. Start Pepecoin daemon 6. verify the daemon is indeed running

• Running Pepecoin Node: You must have a Pepecoin node running with RPC enabled (you can start it by running pepecoind -daemon from the terminal).

• RPC Credentials: Don't forget to add RPC_USER and RPC_PASSWORD in your .env file.

Usage Examples

Initialize the Pepecoin Client

from pepecoin import Pepecoin
from dotenv import load_dotenv
import os

load_dotenv()

# Initialize the Pepecoin client
pepecoin = Pepecoin(
    rpc_user=os.environ.get("RPC_USER"),
    rpc_password=os.environ.get("RPC_PASSWORD"),
    host="127.0.0.1",
    port=29373,
    wallet_name="merchant_wallet"
)

Check Node Connection

if pepecoin.check_node_connection():
    print("Node is connected.")
else:
    print("Node is not connected.")

Create a New Wallet

wallet_created = pepecoin.create_new_wallet(
    wallet_name="merchant_wallet",
    passphrase="secure_passphrase"
)
if wallet_created:
    print("Wallet created successfully.")
else:
    print("Failed to create wallet.")

Generate a New Address

payment_address = pepecoin.generate_new_address(label="order_12345")
print(f"Payment Address: {payment_address}")

Check Wallet Balance

balance = pepecoin.check_balance()
print(f"Wallet Balance: {balance} PEPE")

Check for Payments

payment_received = pepecoin.check_payment(
    address=payment_address,
    expected_amount=10.0
)
if payment_received:
    print("Payment received.")
else:
    print("Payment not yet received.")

Lock and Unlock Wallet

# Unlock the wallet
pepecoin.unlock_wallet(
    wallet_name="merchant_wallet",
    passphrase="secure_passphrase",
    timeout=60  # Unlock for 60 seconds
)

# Lock the wallet
pepecoin.lock_wallet(wallet_name="merchant_wallet")

Mass Transfer Funds

from_wallets = ["wallet1", "wallet2"]
passphrases = ["passphrase1", "passphrase2"]
to_address = "PMainWalletAddress1234567890"

tx_ids = pepecoin.mass_transfer(
    from_wallets=from_wallets,
    to_address=to_address,
    passphrases=passphrases
)
print(f"Mass transfer transaction IDs: {tx_ids}")

---

Future Improvements

• Synchronous vs. Asynchronous: The AuthServiceProxy class is synchronous. If we need asynchronous support, we might need to use an asynchronous RPC client or run synchronous code in a thread pool.

API Reference

__init__

Initialize the Pepecoin RPC connection.

def __init__(
    self,
    rpc_user: str,
    rpc_password: str,

  • rpc_password: RPC password.
  • host: Host where the Pepecoin node is running.
  • port: RPC port of the Pepecoin node.
  • wallet_name: Name of the wallet to interact with (optional).

init_rpc

  • to_address: The target Pepecoin address to transfer funds to.
  • passphrases: List of passphrases for the wallets (if encrypted).

---

Security Considerations

• Passphrases: Never hardcode passphrases in your code. Use secure methods to store and retrieve them (e.g., environment variables, secure key management systems).
• RPC Credentials: Protect your RPC credentials. Do not expose them in logs or version control.
• Wallet Encryption: Always encrypt wallets that hold real funds.
• Node Security: Ensure your Pepecoin node is secure, with proper firewall settings and access controls.
• SSL/TLS Encryption: Consider using SSL/TLS for RPC communications.
