CONTRIBUTING GUIDE

Learn the Basics

Start your journey with the public Hedera network by learning the basics — from understanding the network’s architecture to who’s building next-generation applications, you’ll have a proper foundation to start building.

Hedera Explained

Understand the basics of Hedera network node types, developer services & API, governance, $HBAR, and more by reading this introduction to Hedera.

How It Works

Hedera is an open-source, public, proof-of-stake network. Hedera network services offer low & fixed fees,10k TPS, and instant transaction finality.

Core Concepts

Dive into the technical core concepts of Hedera. Learn everything from how accounts are created to scheduling transactions and querying on-ledger data.

Hedera Ecosystem

From permissionless web3 startups and NFT projects to Fortune 500 companies, take a look into who’s choosing Hedera to build their next-generation application.

Set Up Your Environment

Start developing on the Hedera network today by following the step-by-step guide, which will provide you with everything you need to understand the essentials and start building web3 applications. Alternatively, you can start building with an end-to-end video tutorial.

Step-by-Step Guide

1. Testnet Access

Create your developer profile on the portal to get your testnet account ID, keys, and test HBAR.

2. Environment Setup

Choose an SDK and set up your development environment. Write code in Javascript, Java, or Go.

3. Create an Account

Generate keys & learn how to create an account on the Hedera Testnet using the SDK — you’ll submit a transaction, receive an account ID and learn how to check your balance.

4. Transfer HBAR

Send a balance transfer transaction by transferring HBAR from your account to another on Hedera Testnet. You'll create and verify a transfer transaction and learn how to get the account balance.

Build Your First Decentralized Application (DApp)

Learn how to use Hedera network services and build your first dApp by following these step-by-step tutorials.

Create & Deploy a Smart Contract

Create a Solidity Smart Contract that interacts with the Hedera Token Service, bringing full programmability into your token-based application.

Create Fungible Tokens

Service to create fungible tokens that map to ERC-20 standards and scale to 10,000+ TPS.

Create Non-Fungible Tokens

Use the Hedera Token Service to create non-fungible tokens that map to ERC-721 standards and scale to 10,000+ TPS.

Write Verifiable Data to Hedera

Use the Hedera Consensus Service as a decentralized message bus to write immutable, verifiable, and consensus timestamped data at 10k+ TPS and $0.0001 per message.

Hedera Network Services

Learn about the suite of network services offered on Hedera and how each can be used to build decentralized applications.

Smart Contracts

An EVM-based smart contract service. Build and deploy contracts using Solidity or port over an existing smart contract with ease.

Token Service

Configure, mint, and manage native fungible and non-fungible tokens or using ERC-20 & 721 standards on the Hedera network.

Consensus Service

Incorporate scalable, real-time, auditable logs of events with consensus timestamps into any web2 or permissionless web3 application.

File Service

Hedera File Service is a decentralized file storage platform that allows users to securely store and access files on a distributed network of computers using hash as a file identifier.

EVM-Compatible Tools

Continue utilizing familiar Ethereum development tools such as Web3.js, Truffle, Ethers, Hardhat, and Foundry to build on Hedera using the JSON-RPC Relay. As an Ethereum developer, your workflow does not have to change.

Create an ECDSA Account

Create an ECDSA account that works with JSON-RPC to use EVM-compatible tooling, libraries, and wallets.

Set Up Metamask

Add a Hedera network to Metamask using the Hashio implementation of the JSON-RPC Relay. Sign transactions and queries to test your Hedera-powered application.

Libraries & Tooling

Integrate Hedera into Ethers, web3.js, Truffle, or Hardhat for building, debugging, and deploying your smart contract applications on the Hedera network.

JSON-RPC Relay

JSON-RPC makes it easy for existing EVM-based libraries, dev tools, and wallets to work effortlessly on Hedera.

Developer Tools and Integrations

Explore various developer tools and resources on Hedera that help make building and maintaining your decentralized application even easier.

Network Explorers

Visualizations & APIs for historical network data, including account & token details, transactions, tokens, contracts, topics, and schedules.

Wallet Integrations

Onboard users into your application with ease. Wallets on Hedera offer transaction signing, management of HBAR, NFTs, and fungible tokens.

Network Bridge

HashPort is a public utility that facilitates the bi-directional movement of digital assets between public networks in a quick, secure, and cost-effective way.

Monitoring & Security

Use Open Zeppelin’s Defender Admin, Relay, and Sentinels for administrative, security, and monitoring functionality for Smart Contracts on Hedera.

Local Node

Learn how to set up your own Hedera local network, including consensus & mirror nodes, using Docker.
