clob-client-v2
clob-client-v2 is a TypeScript client library designed for interacting with Polymarket's Central Limit Order Book (CLOB) Version 2. It enables developers to build applications for trading prediction market outcomes on Polygon and Amoy testnet. The library supports placing resting limit orders (Good-Til-Cancelled) and market orders (Fill-or-Kill or Fill-and-Kill) via a simple API. Authentication is handled through a two-tier system: Level 1 uses EIP-712 wallet signatures to derive or create API keys, while Level 2 utilizes HMAC credentials for executing orders, cancellations, and retrieving account data or order books. The client prioritizes developer experience with robust error handling that can be configured to throw typed exceptions or return customizable error objects. Installation is via standard package managers like npm or yarn. Key features include support for multiple order types, seamless integration with viem for wallet management, and methods to manage the full trading lifecycle from authorization
