Hypercall, the options trading platform within the Hyperliquid ecosystem developed by the Synapse team, has officially open-sourced its Rust SDK on GitHub under the repository name hypercall-rust. The SDK comprises five core modules: hypercall-client (API and WebSocket client), hypercall-hyperliquid (Hyperliquid hedging integration), hypercall-liquidator (standard margin liquidation reference implementation), hypercall-sdk-types (shared type definitions), and hypercall-ws-protocol (WebSocket protocol DTOs). This open-source move lowers integration barriers for developers, enabling third-party tools and quantitative strategies to build on standardized infrastructure.
Hypercall also disclosed that the SDK release is a critical step toward onboarding more market makers. Over the past two weeks, the team has engaged with multiple market-making firms and is actively pushing forward their launch on the platform. The addition of professional market makers is expected to significantly improve quote density, reduce slippage, and enhance overall liquidity depth for Hypercall's options market. For the Hyperliquid ecosystem's decentralized derivatives landscape, this development marks a necessary progression toward a more competitive and efficient trading environment.
