Polymarket

POST /agent/polymarket/approvals shows max but CLOB returns allowance: 0

Root cause: approval targeted the wrong USDC contract or wrong exchange spender.

Polymarket on Polygon enforces allowance against USDC.e (0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174), not pUSD or native USDC. And orders settle on the V1 exchange (0x4bFb41d5B3570DeFd03C39a9A4D8dE6Bd8B8982E), not V2 — even though the SDK is clob-client-v2. The CLOB's GET /version returns 1.
