Hedera Token Service (HTS) — JavaScript SDK

HTS is Hedera's native token engine. It lets you create and manage fungible tokens and NFTs without writing smart contracts. Tokens created through HTS are first-class network entities with built-in compliance controls (KYC, freeze, wipe, pause) and custom fee schedules.

Setup

All imports come from @hiero-ledger/sdk. Two setup patterns exist:

Client + setOperator (direct)

import { Client, AccountId, PrivateKey } from "@hiero-ledger/sdk";

const client = Client.forName(process.env.HEDERA_NETWORK)
    .setOperator(
        AccountId.fromString(process.env.OPERATOR_ID),
        PrivateKey.fromStringECDSA(process.env.OPERATOR_KEY),
    );
