What is Claw Arbs?
Claw Arbs is desktop software for connecting prediction markets and sportsbooks. Each strategy agent has its own venue selection, market filters, edge threshold, execution behavior and exposure limits. The software distinguishes a paired arbitrage trade from a one-sided value bet, and it lets an agent run in paper mode before live execution. Credentials are stored locally in the desktop application.

Workflows with Claw Arbs
Test a cross-venue strategy
Connect two supported venues, create an agent, choose matching market types and configure edge and exposure limits. Inspect paper results before selecting live mode.
Separate value from arbitrage
Choose whether the strategy needs two offsetting legs or one directional position. Size the exposure for that specific mode.
Add a sportsbook
Use an existing community calibration or the point-and-click flow, then verify the selected odds and bet type before enabling execution.
