Explore the docs

The Hedera documentation is organized into seven sections. Pick the one that fits what you’re building.

Fundamentals — accounts, keys, transactions, tokens, hashgraph, and networks.

Deploy Solidity contracts with MetaMask, Hardhat, Foundry, and JSON-RPC relay.

JavaScript, Java, and Go SDKs for direct access to Hedera services.

Tokenization, AI agents, governance, sustainability, and developer tools.

Run your own mirror node, JSON-RPC relay, or consensus node.

REST API, Protobuf, HCS gRPC, Status, and Contract Verification APIs.

FAQs, contributing, style guide, glossary, and community resources.

Common questions on accounts, HBAR, governance, getting started, and the community.

Popular quickstarts

Build on Hedera

Pick the Hedera service that powers your app — accounts, smart contracts, native tokens, or consensus — then try it in your browser with no setup.

Account Service

Create and manage Hedera accounts, keys, staking, and auto-account creation from a public key.

Smart Contracts

EVM-compatible Solidity contracts with access to native Hedera services via system contracts.

Configure, mint, and manage native fungible and non-fungible tokens with built-in compliance.

HTSERC-20ERC-721

Consensus Service

Scalable, real-time audit logs with consensus timestamps. 10k+ TPS at $0.0001 per message.

Try it live

Run code in the Playground, scaffold a contract, demo an agent, or preview a token mint — no setup.

Developer tools & resources

Network Explorers

Visualize accounts, tokens, transactions, and contracts on Hedera.

Deploy and operate a Hiero/Hedera network locally with Kubernetes — perfect for development and testing.

Connect AI assistants like Claude and Cursor to Hedera with the Model Context Protocol server.

Ethereum-compatible JSON-RPC endpoint — connect MetaMask, Hardhat, Foundry, and ethers.js to Hedera.

Wallet Integration

Connect Hedera-native and EVM wallets — HashPack, Blade, Kabila, MetaMask, and more.

Oracle Networks

Pull external data into Hedera smart contracts — Chainlink, Pyth, Supra, and other oracle providers.
