Hyperliquid TypeScript SDK vs Volmex

The Hyperliquid TypeScript SDK is a comprehensive, community-maintained client library for the Hyperliquid API, supporting all major JavaScript runtimes including Node.js, Deno, Bun, and browser environments. Written in TypeScript with full type coverage, the SDK provides ergonomic abstractions for REST API calls and WebSocket subscriptions, making it easy to build Hyperliquid integrations in the web ecosystem. The library handles authentication, request signing, WebSocket reconnection logic, and response parsing—letting developers focus on business logic rather than protocol details. It supports the full Hyperliquid API surface including order management, account queries, market data streaming, and HyperEVM interactions. With active maintenance and growing adoption in the developer community, this SDK is the standard choice for frontend applications and Node.js trading systems interfacing with Hyperliquid, bridging the gap for JavaScript developers entering the ecosystem.

Volmex

Volmex Finance is the leading protocol for crypto volatility products, offering on-chain implied volatility indices and derivatives. Their flagship products — BVIV (Bitcoin Implied Volatility Index) and EVIV (Ethereum Implied Volatility Index) — give traders a standardized way to hedge or speculate on market volatility, similar to how TradFi investors use the VIX. Volmex integrated with Hyperliquid via HIP-3, bringing perpetual volatility trading directly to the platform's high-performance order book. This allows Hyperliquid users to take long or short positions on crypto volatility without leaving the ecosystem. BVIV and EVIV are derived from options market data across major venues, providing transparent and manipulation-resistant benchmarks. For portfolio managers, volatility products serve as powerful hedging tools — when markets crash, volatility spikes, making BVIV/EVIV longs an effective hedge against spot or perp losses. Volmex's integration represents a significant step in bringing sophisticated TradFi-grade instruments to DeFi, deepening Hyperliquid's product suite beyond directional perpetuals and giving traders a complete toolkit to express volatility views and manage risk across all market conditions.
