This guide demonstrates how to use Python to interact with PumpSwap, a fast decentralized exchange (DEX) on the Solana blockchain. We'll explore the pumpswap-sdk for essential operations like fetching token prices, executing buy and sell orders, and accessing pool data, complete with practical code examples and setup instructions.
Prerequisites
Before starting, ensure you have the following ready:
- Python 3.12 or higher installed
- A Solana wallet private key
- Poetry or pip for dependency management
Installation
Install the PumpSwap SDK using your preferred package manager:
- With Poetry:
poetry add pumpswap-sdk - With pip:
pip install pumpswap-sdk
Environment Configuration
Create a .env file in your project root and configure these variables:
HTTPS_RPC_ENDPOINT=https://api.devnet.solana.com
BUY_SLIPPAGE=0.3
SELL_SLIPPAGE=0.1
SWAP_PRIORITY_FEE=1500000Getting Started with the SDK
Initializing the SDK
Begin by importing the necessary modules and initializing the SDK:
from pumpswap_sdk import PumpSwapSDK
from solders.pubkey import Pubkey
sdk = PumpSwapSDK()
mint = "your_pumpswap_token_mint" # Replace with your token mint address
user_private_key = "your_private_key_here" # Replace with your private keyFetching Token Prices
Retrieve the current price of a token using its mint address:
token_price = await sdk.get_token_price(mint)
print(f"Token Price: {token_price}")Buying Tokens
Execute a buy order by specifying the amount of SOL to spend:
sol_amount = 0.0001
result = await sdk.buy(mint, sol_amount, user_private_key)
print(result)Selling Tokens
Sell a specific quantity of tokens:
token_amount = 10.0
result = await sdk.sell(mint, token_amount, user_private_key)
print(result)Advanced Usage Tips
- Adjust slippage tolerance in the
.envfile to manage price impact during trades. - Use the
SWAP_PRIORITY_FEEto prioritize transaction processing on the network. - Always test transactions on the Devnet before executing them on Mainnet.

Frequently Asked Questions
What is PumpSwap?
PumpSwap is a decentralized exchange on the Solana blockchain, optimized for high-speed transactions and low fees. It enables users to swap tokens directly from their wallets without intermediaries.
Why use the PumpSwap SDK?
The SDK simplifies interactions with the PumpSwap protocol, allowing developers to integrate trading functionalities into applications with minimal code. It handles complex blockchain operations behind the scenes.
How do I manage security risks?
Never expose your private key in code. Use environment variables or secure vaults for key management. Always verify transactions on Devnet before committing real funds.
What networks are supported?
The SDK currently supports Solana Devnet for testing. For mainnet operations, replace the RPC endpoint with a mainnet provider.
Can I customize transaction parameters?
Yes, the SDK allows adjustments for slippage, priority fees, and RPC endpoints. These can be configured in the .env file or programmatically within your code.
Where can I find more resources?
For detailed documentation and community support, refer to the official SDK repository. 👉 Access developer tools and resources
