Grotaro

The cross-platform workspace for short-duration crypto prediction markets. Watch structure, compare venues, move capital, and act when the setup is there.

5-Minute Markets

Fast short-duration structure

Monitor 5-minute crypto up or down contracts with a clean trading view that keeps price, strike, execution, and account context on one screen.

Keep short-duration contracts, live pricing, and execution controls in one place.
See the price to beat clearly instead of piecing context together across tabs.
Designed for traders who generate ideas by watching market behavior in real time.

15-Minute Cross-Platform Markets

Compare Polymarket and Kalshi in one workflow

Watch equivalent 15-minute markets side by side, compare the price to beat, and route into the better setup without losing time to context switching.

View the Polymarket and Kalshi side together instead of separately.
See where the market is asking too much, too little, or giving you a cleaner entry.
Built for active traders who turn structure and divergence into repeatable setups.

XARB Depth Dashboard

A broader view of market depth

Watch order-book depth across venues in one place and find ideas by observing pressure, imbalance, and structure before a trade is placed.

Monitor multiple assets at once instead of guessing from one isolated market.
Use visible depth and divergence to shape entries, exits, and sizing.
Built for traders who do their own analysis and want more ways to express a view.
