4. Rust API Clients

Several Rust implementations exist for high-performance trading bots. Most use reqwest for HTTP and tokio-tungstenite for WebSocket connections.

See our Polymarket Rust API guide for implementation examples and best practices.

Analytics and Data Tools

Analytics tools help traders understand market dynamics, track performance, and identify opportunities. These tools use the Polymarket Gamma API for market data and the Polymarket CLOB API for position tracking. See the official gamma-api.polymarket.com endpoint documentation.

1. Portfolio Trackers

Portfolio trackers monitor positions across all markets, calculate real-time P&L, and provide historical performance analysis. Most implementations include:

See our Polymarket portfolio tracker guide for recommendations and implementation details.

2. Whale Tracking Tools

Whale tracking tools monitor large wallet movements and identify profitable traders. These tools analyze on-chain data to track positions, P&L, and trading patterns.

PolyTrack is the most comprehensive whale tracking tool, with real-time alerts, Dev Picks (curated alpha wallets), and advanced analytics. See our whale tracking guide for more tools and strategies.

3. Market Scanners

Market scanners identify trading opportunities by analyzing market data in real-time. Common use cases include:

4. Data Analysis Tools

Data analysis tools help traders understand market trends, historical patterns, and statistical relationships. These tools typically use:

• GraphQL Subgraph: Historical on-chain data via Polymarket Subgraph
• Gamma API: Real-time market data and metadata
• CSV exports: Custom analysis in Python, R, or Excel
• Jupyter notebooks: Interactive data analysis and visualization

Developer Utilities

Developer utilities provide helper functions, testing tools, and frameworks to speed up development. These tools abstract common patterns and reduce boilerplate code.

1. Order Signing Libraries

Order signing is required for all CLOB API orders. Several libraries provide EIP-712 signing functionality:

2. WebSocket Clients

WebSocket clients provide real-time price feeds and orderbook updates. See our Polymarket WebSocket tutorial for implementation examples.

3. Testing Frameworks

Testing frameworks help developers test their bots and tools without risking real funds:

4. GraphQL Query Builders

GraphQL query builders simplify querying the Polymarket Subgraph and Gamma API. These tools provide type-safe query construction and response parsing.
