Learn the Basics

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
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
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.	accounts.md
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

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.

1. Testnet Access	Create your developer profile on the portal to get your testnet account ID, keys, and test HBAR.	testnet-access.md
2. Environment Setup	Choose an SDK and set up your development environment. Write code in Javascript, Java, or Go.	environment-set-up.md
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
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

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 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
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
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

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.png
Token Service	Configure, mint, and manage native fungible and non-fungible tokens using ERC-20 & 721 standards on the Hedera network.	tokens	token service.png
Consensus Service	Incorporate scalable, real-time, auditable logs of events with consensus timestamps into any web2 or permissionless web3 application.	consensus	consensus service.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.	file-storage	file service (1).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.	generate-a-new-key-pair.md	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. Hashio is a free implementation of the relay, offered by Swirlds Labs.	https://github.com/hashgraph/hedera-json-rpc-relay	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.
