MoonfunSDK - BSC Meme Token Creation Tool

Professional Python SDK for creating and trading Meme tokens on Binance Smart Chain with AI-powered image generation.

Overview

MoonfunSDK enables automated creation of Meme tokens with AI-generated images on BSC. The SDK handles image generation, platform integration, and blockchain transactions through a simple Python interface.

Installation

pip install moonfun-sdk

Requirements:

Python 3.8+
BNB balance ≥ 0.011 (0.01 creation fee + gas)

Quick Start

import os
from moonfun_sdk import MoonfunSDK

# Initialize with private key
sdk = MoonfunSDK(private_key=os.getenv('PRIVATE_KEY'))

# Create Meme token
result = sdk.create_meme(prompt="A happy cat celebrating")

print(f"Token: {result['token_address']}")
print(f"View: https://moonn.fun/detail?address={result['token_address']}")

Core Features

Token Creation (Stable)

AI-generated meme images
Automatic title and symbol generation
One-function deployment to BSC
Integrated with MoonnFun platform

Token Trading (Experimental)

Buy tokens with BNB
Sell tokens for BNB
Automatic slippage handling
Balance queries

API Methods

create_meme()

sdk.create_meme(
    prompt: str,              # Meme description
    symbol: str = None,       # Auto-generated if None
    description: str = None   # Auto-generated if None
) -> dict

Returns:

token_address: Contract address
token_id: Platform token ID
tx_hash: Creation transaction hash
name: Token name
symbol: Token symbol
image_url: Hosted image URL

buy_token() / sell_token()

sdk.buy_token(token_address: str, bnb_amount: float, slippage: float = 0.1)
sdk.sell_token(token_address: str, amount: int, slippage: float = 0.1)

Balance Queries

sdk.get_balance()                           # Returns BNB balance
sdk.get_token_balance(token_address: str)   # Returns token balance (wei)

Configuration

Default Configuration

SDK comes pre-configured with hosted services:

Image API: Hosted service for AI generation
Platform: https://moonn.fun
BSC RPC: Public BSC dataseed node

No additional configuration needed for basic usage.

Custom Configuration

sdk = MoonfunSDK(
    private_key="0x...",
    image_api_url="https://custom-api.com",     # Optional
    platform_url="https://moonn.fun",           # Default
    rpc_url="https://bsc-dataseed.bnbchain.org" # Default
)

Environment Variables

Supported environment variables:

PRIVATE_KEY (required): Ethereum private key
MOONFUN_IMAGE_API_URL (optional): Custom image API endpoint

Security

Private Key Handling

Private keys are used locally only for:

Transaction signing (via eth_account library)
Message signing for authentication

Private keys are NEVER:

Transmitted over network
Stored to disk
Logged to console

Code Verification

Users can audit private key usage in source code:

auth.py: Local signing with eth_account
image_api.py: Sends only signature + address
platform.py: Sends only signature + address
blockchain.py: Local transaction signing via web3.py

Best Practices

# ✅ Use environment variables
sdk = MoonfunSDK(private_key=os.getenv('PRIVATE_KEY'))

# ✅ Use dedicated wallets
# Create new wallet for SDK operations only

# ❌ Never hardcode keys
sdk = MoonfunSDK(private_key="0x123...")  # Don't do this

Gas Costs

Token creation: ~0.011 BNB (0.01 fee + 0.001 gas)
Buy/sell: ~0.0005-0.001 BNB per transaction

Error Handling

from moonfun_sdk import (
    InsufficientBalanceError,
    AuthenticationError,
    TransactionFailedError
)

try:
    result = sdk.create_meme("A funny cat")
except InsufficientBalanceError:
    print("Need more BNB (minimum 0.011)")
except AuthenticationError:
    print("Signature verification failed")
except TransactionFailedError:
    print("Blockchain transaction failed")

Hosted Services

The SDK uses these services:

Image Generation API
- Secured with cryptographic signatures
- Balance-gated (minimum 0.011 BNB)
- Timestamp-bound requests
- Default endpoint: http://moonfun.site
- Users can deploy custom instances
MoonnFun Platform
- Public token launchpad
- Metadata and image storage
- URL: https://moonn.fun
BSC Network
- Public blockchain
- Decentralized infrastructure

Dependencies

Core dependencies:

web3>=6.0.0 - Ethereum interaction
eth-account>=0.8.0 - Private key management
requests>=2.28.0 - HTTP client
httpx>=0.24.0 - Async HTTP client

All dependencies are widely used and audited libraries.
