Monitoring Uniswap Cryptocurrency Prices with Python

ยท

Uniswap is an Ethereum-based exchange protocol that enables seamless ERC20 token swaps. Unlike traditional exchanges requiring buy/sell orders, Uniswap automates market creation, addressing liquidity challenges in decentralized exchanges (DEXs).

Market Observations on Uniswap

Recent trends highlight intriguing price patterns for newly listed tokens, particularly high-volatility assets:

โš ๏ธ Important Note: During peak volatility, Ethereum network congestion often results in exorbitant gas fees ($100+ per transaction), making short-term arbitrage unfeasible.

Automated Price Monitoring Solution

Manually tracking prices wastes valuable time. This Python script delivers real-time alerts when targets are hit.

Technical Setup

!pip install uniswap-python plyer

Configuration Parameters

# Token Addresses (Checksum format)
ETH = "0x0000000000000000000000000000000000000000"
DAI = "0x6B175474E89094C44Da98b954EedeAC495271d0F" 
SUPER = "0xe53EC727dbDEB9E2d5456c3be40cFF031AB40A55"

# Web3 Provider (Infura example)
provider = "https://mainnet.infura.io/v3/YOUR_PROJECT_ID"

Price Fetching Functions

ETH Price Conversion:

def get_token_price(token_address):
    uniswap = Uniswap(None, None, version=2, provider=provider)
    raw_price = uniswap.get_token_eth_input_price(token_address, 10**18)
    return raw_price / 10**18

USD Pricing via DAI:

def get_usd_price(token_address):
    token_eth = get_token_price(token_address)
    dai_eth = get_token_price(DAI)
    return round(token_eth / dai_eth, 4)

Desktop Notification System

from plyer import notification

def alert_price_change(old_price, new_price):
    notification.notify(
        title="Uniswap Price Alert",
        message=f"New Price: ${new_price} | Change: ${round(new_price-old_price,2)}",
        timeout=10
    )

Main Monitoring Loop

import time

current_price = get_usd_price(SUPER)

while True:
    updated_price = get_usd_price(SUPER)
    
    if abs(updated_price - current_price) > 0.05:
        alert_price_change(current_price, updated_price)
        current_price = updated_price
    
    time.sleep(10)  # Check every 10 seconds

FAQ Section

Q: How accurate are Uniswap price feeds?
A: Prices reflect real-time pool ratios with sub-second updates, making them more accurate than centralized exchanges during volatility.

Q: What's the optimal polling interval?
A: 10-30 seconds balances accuracy with node request limits. During high volatility, decrease to 5-10 seconds.

Q: Can I track multiple tokens simultaneously?
A: Yes! Modify the script to maintain a dictionary of token addresses and price thresholds.

Q: Why use DAI instead of USDC for USD pricing?
A: DAI maintains more consistent liquidity pools on Uniswap, reducing price slippage in conversions.

Q: How can I reduce gas fee impacts?
A: Schedule transactions during low-activity periods (typically UTC 0400-0800).
