  • Smart context — Ask “should I trade this?” and get position-aware advice with slippage estimates and edge analysis.
  • Multiple venues — Paper trade with virtual $SIM, then graduate to real USDC on Polymarket or USD on Kalshi.
  • Skills ecosystem — Install pre-built trading strategies or publish your own on ClawHub.
