Polymarket Auto Trading Bot Development
Budget: $20 – $50 USD
Project: Polymarket Automated Trading Bot (Node.js or Python)
I’m looking for a blockchain developer to build a working Polymarket automated trading bot.
Language can be Node.js OR Python — whatever reliably works.
Goal (simple):
Automatically place YES and NO limit orders on Polymarket markets using the official CLOB API.
Core requirements:
Read Polymarket market URLs (CSV or list)
Extract market slug
Fetch YES / NO token IDs from Polymarket (Gamma API)
Place LIMIT GTC orders via Polymarket CLOB
Correct EIP-712 signing
Polygon mainnet (chainId 137)
Important technical points:
Use ethers.js (Node) or web3.py / eth-account (Python)
Wallet must sign orders correctly (no broken signer logic)
Price & size use 18 decimals
Support test/simulation mode vs live trading
Config via .env
