pancakeswap-py 🍪🐍

A Python library based on web3.py, Asyncio, and PancakeSwap V2/V3 contracts, featuring pool creation, liquidity management, liquidity removal, liquidity viewing, swap trading, WBNB/BNB conversion, and more. V2/V3 use consistent syntax as much as possible, making it convenient for beginners to perform DeFi operations on the BSC network.

V3 Examples

Prerequisites

💡 It's recommended to use private or privacy-focused RPC nodes to prevent sandwich attacks

from pancakeswap_py.v3 import PancakeSwapV3, Fee
pancakeswap_v3 = PancakeSwapV3(
    json_rpc=JSON_RPC,
    private_key=PRIVATE_KEY,
)
WBNB = "0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c"
# 💡 Test token with no value
TOKEN = "0x7e216C64f5954758d747e61C3b58062509eE40B8"
amountA = 0.001
amountB = 100

💡 All methods with the auto prefix are wrapped by the author for ease of use by beginners
💡 All slippage defaults to 0.05
💡 Both V2/V3 classes include WBNB/BNB conversion methods: wrap_bnb/unwrap_wbnb
