Summary
Adds full Polymarket prediction market trading support to the Polygon Agent CLI. Agents can browse markets, place limit and market orders on the Polymarket CLOB, manage positions, and handle the on-chain approval flow — all through the existing CLI and smart wallet infrastructure.
Architecture
Uses a 3-address system: the Sequence ecosystem wallet funds a Polymarket proxy wallet (derived via CREATE2 from the builder EOA), which holds USDC.e and outcome tokens. CLOB orders are signed by the EOA with
signatureType=POLY_PROXY. The proxy wallet factory routes all on-chain calls.Commands
