Hyperliquid TypeScript SDK vs Mizu

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.

Mizu

Mizu Labs is an automated yield aggregator protocol deployed on HyperEVM, Hyperliquid's EVM-compatible smart contract layer. Designed for ETH and BTC holders seeking to maximize returns within the Hyperliquid ecosystem, Mizu issues liquid wrapper tokens — hypeETH and hypeBTC — representing bridged assets that are continuously deployed across the highest-yielding HyperEVM protocols. Under the hood, Mizu automates liquidity routing into established platforms including HyperLend, HypurrFi, Felix, and Harmonix, compounding rewards and rebalancing positions without requiring manual intervention from depositors. This set-and-forget approach makes Mizu ideal for users who want exposure to HyperEVM's rich DeFi landscape — spanning lending markets, stablecoin minting, and structured yield products — without the overhead of active position management. By aggregating liquidity from many depositors, Mizu accesses yield opportunities at scale that would be inefficient for individual wallets. The protocol participates in points programs across its integrated protocols, passing accumulated rewards back to hypeETH and hypeBTC holders. As HyperEVM matures as a composable DeFi layer beneath Hyperliquid's core trading infrastructure, Mizu Labs positions itself as the primary yield optimization engine for bridged capital seeking productive, automated deployment.
