​
Wallet Approvals

Before selling tokens, your wallet needs to approve the Polymarket contracts:
  • USDC Approval - For buying shares
  • CTF Approval - For selling shares (Conditional Token Framework)
LuckyLobster handles these approvals automatically when needed.

​
Troubleshooting

  • Verify your proxy address is correct
  • Check that you have USDC in your Polymarket wallet
  • Ensure you’re connected to Polygon network
  • Check the /balance endpoint for current balance
  • Make sure you have MATIC for gas fees
  • Verify funds are in your proxy wallet, not EOA
LuckyLobster auto-approves CTF when needed. If you get approval errors:
  • Try the /wallet/approve endpoint manually
  • Check for pending transactions on PolygonScan
