Release v2.20.0 · pmxt-dev/pmxt

Address Watcher & Subscriber System: Introduced watchAddress() and unwatchAddress() methods on BaseExchange, along with a new subscriber infrastructure (core/src/subscriber/) for monitoring on-chain address activity. Supports optional address parameter for flexible subscription management.
GoldSky Integration: Added GoldSky GraphQL subscription implementation (core/src/subscriber/external/goldsky.ts) for real-time on-chain event streaming. Integrated into the Limitless exchange for live data feeds.
Whale Tracker Examples: Added Python and TypeScript example scripts (core/examples/social/) demonstrating how to track large-position holders using the SDK.
SDK: buildOrder / submitOrder Support: Both the Python and TypeScript SDKs now expose buildOrder() and submitOrder() methods, along with the BuiltOrder type, enabling the two-step order workflow introduced in v2.19.0.
Trade outcomeId Field: Added outcomeId (asset ID) to the Trade type for clearer asset-level trade identification.

Kalshi Orderbook: Switched from the removed legacy orderbook field to orderbook_fp, fixing broken orderbook fetches on the Kalshi exchange.
Limitless baseUrl Parameter: Fixed incorrect base URL handling in the Limitless exchange configuration.
Exchange Imports: Fixed missing or incorrect index.ts imports across exchange modules.
Test Infrastructure: Replaced vitest imports with Jest globals in price tests to match the project's test runner.
Whale Tracker Examples & SDK Bugs: Fixed issues in example scripts and resolved minor SDK client bugs.
TypeScript SDK Merge Conflicts: Resolved merge conflicts in the TypeScript SDK client.

Polymarket WebSocket: Enriched the Polymarket websocket implementation with improved event handling and user position tracking.
Limitless WebSocket & GoldSky Integration: Refactored the Limitless exchange to integrate GoldSky watcher and subscriber, with improved websocket configuration.
Exchange Interfaces: Refactored BaseExchange interfaces, updated type names, and standardized exchange interface implementations across Polymarket, Limitless, Myriad, and others.
Price Helpers: Centralized exchange price helpers and standardized argument building across exchanges.
Watcher Dispatch Optimization: Updated the watcher to dispatch events only when there is an actual change, reducing unnecessary notifications.
OpenAPI & API Reference: Auto-regenerated openapi.yaml and API_REFERENCE.md to reflect all new endpoints and types.
SDK Models & Documentation: Updated Python and TypeScript SDK models, API reference docs, and added client example code.
