What is Polymarket Proxy Trader?
The Polymarket Proxy Trader is a robust technical solution designed for users who interact with Polymarket via proxy wallets (Gnosis Safe). It specifically addresses a critical limitation in official SDKs where balance checks for selling operations incorrectly reference the signing wallet (EOA) rather than the proxy wallet, often leading to failed transactions. By utilizing Openclaw Skills, this tool ensures that balance lookups and trade executions are handled with precision.
This skill integrates seamlessly with SkillPay for automated micro-payments (0.001 USDT per call), making it a professional-grade tool for developers and high-frequency traders. It provides the necessary infrastructure to handle complex signing requirements and asset type mappings required for prediction market success.
Polymarket Proxy Trader Use Cases
- Resolving the common proxy wallet balance bug found in official Polymarket SDKs.
- Checking accurate USDC and conditional token balances for Gnosis Safe accounts.
- Executing automated market and limit orders on prediction markets.
- Integrating Polymarket trading capabilities into larger automated workflows using Openclaw Skills.
- Managing prediction market positions via AI-driven commands.
How Polymarket Proxy Trader Works
- The user provides a command to check balance or execute a trade through the AI interface.
- The skill triggers a micro-payment of 0.001 USDT via the SkillPay.me API to authorize the transaction.
- Upon authorization, the skill utilizes the provided private key to sign requests for the Polymarket CLOB API.
- To fix the balance bug, the skill explicitly sets the funder parameter to the proxy wallet address during balance and allowance checks.
- The skill submits the trade (limit or market) or returns the corrected balance data to the user.
- All sensitive operations are handled locally to ensure private keys are never exposed.
