Request your private beta API key on Discord to start trading with the SDK.
The Predexon Trade SDK is a noncustodial TypeScript SDK for trading on prediction markets. All signing happens locally—private keys never leave your environment.

Architecture

The SDK provides a single unified client for two venues:
  • Polymarket (Polygon) via Polymarket CLOB
  • Kalshi (Solana) via DFlow swap flow
The SDK handles signing locally and coordinates with Predexon APIs for required venue workflows.
