Native SDKs

Build on Hedera using the JavaScript, Java, Go, Swift, and Rust SDKs — full access to HTS, HCS, scheduled transactions, smart contracts, and the file service.

Browse by section

Every topic in the Native SDKs tab, organized by area.

Quickstart

Install the SDK in JavaScript, Java, or Go and send your first transaction.

SDK Fundamentals

Client, address book, HBAR types, specialized types, and error handling.

Keys

Generate, import, list, threshold, and mnemonic-recover keys.

Transactions

Form, sign, submit, batch — plus receipts, records, and multisig.

Accounts

Create, update, transfer, allowance, balance, and info queries.

Token Service

Define, mint, burn, transfer, airdrop, freeze, pause, wipe — full HTS.

Consensus Service

HCS topics — create, update, submit messages, subscribe to mirror nodes.

Scheduled Transactions

Multi-party signing — create, sign, get info, and execute on threshold.

Smart Contracts

Deploy, call, update — call Solidity contracts from native SDKs.

File Service

On-network file storage — create, append, update, delete, get contents.

Tutorials

Step-by-step guides — tokens, consensus, scheduled, advanced HSM, MCP.

Local Development

Local node, CLI tools, Gitpod, and Codespaces cloud environments.

Pick your language

All Hedera SDKs share the same API surface — pick the language that fits your stack.

JavaScript / TypeScript

Node.js or browser — npm install @hashgraph/sdk.

Java

JDK 11+ — Maven or Gradle integration for enterprise apps.

Go

go get github.com/hashgraph/hedera-sdk-go.

Native services from the SDK

First-class access to every Hedera service — no JSON-RPC layer, no gas auctions, no surprises.

Create a Token

Fungible or NFT — define properties, supply, and admin keys in one transaction.

HTSTokens

Submit a Consensus Message

Timestamped, ordered, immutable messages on HCS topics for any payload.

HCSMessaging

Schedule a Transaction

Wait for multi-party signatures before executing — built-in multisig coordination.

HSSMultisig

Create an Account

Generate a new Hedera account in code — fund, query balance, transfer HBAR.

AccountsHBAR

Batch Transactions

Atomic execution of multiple transactions — all succeed or all fail.

BatchAtomic

Signature Provider

Provider, Signer, and Wallet APIs — integrate hardware wallets and HSMs.
