The README opens with

A terminal agent for Polymarket’s BTC Up or Down 5-minute markets.

It watches the live 5m window, asks TypeSafe Jev whether BTC finishes UP or DOWN vs the window open, and either abstains or buys once and holds to resolution. Default mode is dry-run (no real orders). Live trading is optional.

For live trading only: a Polygon wallet that already works on Polymarket (connected, funded with USDC.e, able to trade in the browser). This project does not set allowances or deposits for you.
