Layer gives prediction-market developers one interface to find equivalent markets, compare live prices, execute trades, and track what actually happened.
Kalshi and Polymarket word the same event differently. Layer finds the equivalent markets so you don’t hand-map tickers to token IDs.
Prices, spreads, and liquidity for matched markets, side by side. See which venue has the better trade.
A price gap isn’t profit. Layer shows fees and execution costs so you can tell whether an arbitrage is still positive after costs.
Same call to place or cancel an order on Kalshi or Polymarket. Change the venue, keep the code.
After an order is sent: what filled, what you hold, and where your money is, in one shape across venues.
Run strategies against historical prices and order books before risking real money.
Matching, prices, execution, and fills for Kalshi and Polymarket, without rebuilding the plumbing.
