Introduction

HieroKit is a developer experience (DX) toolkit for building on the Hiero/Hedera network. It sits on top of the official @hiero-ledger/sdk and Mirror Node APIs.

Why HieroKit?

• Simplified Interactions: Complex flows (like multi-sig, smart contract interactions) are streamlined.
• Best Practices: Transaction lifecycle handling, retries, and status tracking are built-in.
• Ergonomic: Designed to feel natural for modern TypeScript developers.

Mental Model

If hiero-sdk-js shows HOW to build and execute a transaction, HieroKit shows HOW TO USE a transaction safely and consistently in real applications.
