Learn the Basics

Hedera ExplainedUnderstand 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-hashgraphhedera explained.png
How It WorksHedera 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-workswhy hedera.png
Core ConceptsDive into the technical core concepts of Hedera. Learn everything from how accounts are created to scheduling transactions and querying on-ledger data.core-conceptscore concepts.png
Hedera EcosystemFrom 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/ecosystemcase studies.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.

1. Testnet AccessCreate your developer profile on the portal to get your testnet account ID, keys, and test HBAR.introduction.mdtestnet access (1).png
2. Environment SetupChoose an SDK and set up your development environment. Write code in Javascript, Java, or Go.environment-set-up.mdenvironment setup (1).png
3. Create an AccountGenerate 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.mdcreate an account.png
4. Transfer HBARSend 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.mdtransfer 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 ContractCreate 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.mdcreate & deploy a smart contract.png
Create Fungible TokensService to create fungible tokens that map to ERC-20 standards and scale to 10,000+ TPS.create-and-transfer-your-first-fungible-token.mdfungible tokens.png
Create Non-Fungible TokensUse 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.mdnon-fungible tokens.png
Write Verifiable Data to HederaUse 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.mdwrite 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 ContractsAn EVM-based smart contract service. Build and deploy contracts using Solidity or port over an existing smart contract with ease.smart-contractssmart contracts.png
Token ServiceConfigure, mint, and manage native fungible and non-fungible tokens or using ERC-20 & 721 standards on the Hedera network.token-servicetoken service.png
Consensus ServiceIncorporate scalable, real-time, auditable logs of events with consensus timestamps into any web2 or permissionless web3 application.consensus-serviceconsensus service.png
File ServiceHedera 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-1-1file 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 AccountCreate 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.jscreate ECDSA account.png
Set Up MetamaskAdd 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.mdsetup metamask.png
Libraries & ToolingIntegrate 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/toolslibraries & tooling.png
JSON-RPC RelayJSON-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-relayJSON-RPC relay.png
