JavaScript SDK

A JavaScript SDK wraps the JSON-RPC interface of a chain or service into idiomatic JavaScript and TypeScript. Ethers.js, viem, and the Hyperliquid SDK are the standard ones in their respective ecosystems. SDKs handle signing, request serialization, and error parsing — none of which most developers want to write by hand.

See also: RPC (Remote Procedure Call), Blockchain, JWT (JSON Web Token).
