What is HieroKit? ​

HieroKit is a flow-based TypeScript toolkit that wraps the Hiero/Hedera SDK with higher-level primitives for safe, production-ready transactions.

  • Opinionated Client abstraction on top of @hiero-ledger/sdk
  • Flow-based transaction lifecycles with retries and timeouts
  • React hooks for declarative, UI-friendly access to accounts, tokens, and flows

React example ​

If you prefer to start from a working example, check out the tiny React app in the source tree (src/react/example.tsx). This is a demo-only component and not part of the public API surface.

It shows how to:

  • Configure HieroProvider for testnet
  • Use useTransferHbar to send HBAR
  • Use useTransferPreview to estimate fees
  • Use useTransferHistory to inspect recent transfers
