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.	https://hedera.com/learning/hedera-hashgraph/what-is-hedera-hashgraph	landing-hedera-explained-icon.png
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.	https://hedera.com/how-it-works	why hedera.png
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.	core-concepts	core concepts.png
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.	https://hedera.com/ecosystem	case-studies-icon.png

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.

{% tabs %} {% tab title="Step-by-Step Guide" %}

1. Testnet Access	Create your developer profile on the portal to get your testnet account ID, keys, and test HBAR.	introduction.md	Broken link
2. Environment Setup	Choose an SDK and set up your development environment. Write code in Javascript, Java, or Go.	environment-set-up.md	environment setup (1).png
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.	create-an-account.md	create-an-account-icon.png
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.	transfer-hbar.md	transfer hbar.png

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.	deploy-a-contract-using-the-hedera-token-service.md	create & deploy a smart contract.png
Create Fungible Tokens	Service to create fungible tokens that map to ERC-20 standards and scale to 10,000+ TPS.	create-and-transfer-your-first-fungible-token.md	fungible-tokens-icon.png
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.	create-and-transfer-your-first-nft.md	non-fungible-tokens-icon.png
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.	submit-your-first-message.md	write verifiable data.png

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.	smart-contracts	smart-contracts-icon.png
Token Service	Configure, mint, and manage native fungible and non-fungible tokens or using ERC-20 & 721 standards on the Hedera network.	token-service	token-service-icon.png
Consensus Service	Incorporate scalable, real-time, auditable logs of events with consensus timestamps into any web2 or permissionless web3 application.	consensus-service	consensus-service-icon.png
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.	readme-1-1	file-service-icon.png

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.	https://github.com/hashgraph/hedera-json-rpc-relay/blob/main/docs/examples/account-alias-ecdsa.js	create ECDSA account.png
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.	https://github.com/hashgraph/hedera-json-rpc-relay/blob/main/docs/transfer-guide.md	setup metamask.png
Libraries & Tooling	Integrate Hedera into Ethers, web3.js, Truffle, or Hardhat for building, debugging, and deploying your smart contract applications on the Hedera network.	https://github.com/hashgraph/hedera-json-rpc-relay/tree/main/tools	libraries & tooling.png
JSON-RPC Relay	JSON-RPC makes it easy for existing EVM-based libraries, dev tools, and wallets to work effortlessly on Hedera.	json-rpc-relay.md	JSON-RPC relay.png

Developer Tools and Integrations

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