Explore the docs
The Hedera documentation is organized into seven sections. Pick the one that fits what you’re building.
Learn
Fundamentals: accounts, keys, transactions, tokens, hashgraph, and networks.
EVM Developers
Deploy Solidity contracts with MetaMask, Hardhat, Foundry, and JSON-RPC relay.
Native SDKs
JavaScript, Java, and Go SDKs for direct access to Hedera services.
Solutions
Tokenization, AI agents, governance, sustainability, and developer tools.
Operators
Run your own mirror node, JSON-RPC relay, or consensus node.
Reference
REST API, Protobuf, HCS gRPC, Status, and Contract Verification APIs.
Support
FAQs, contributing, style guide, glossary, and community resources.
Pick the Hedera service that powers your app: accounts, smart contracts, native tokens, or consensus, then try it in your browser with no setup.
Consensus Service
Scalable, real-time audit logs with consensus timestamps. 10k+ TPS at $0.0001 per message.
HCSMessaging
Token Service
Configure, mint, and manage native fungible and non-fungible tokens with built-in compliance.
HTSERC-20ERC-721
Smart Contracts
EVM-compatible Solidity contracts with access to native Hedera services via system contracts.
SolidityEVM
Account Service
Create and manage Hedera accounts, keys, staking, and auto-account creation from a public key.
AccountsHBAR
Try it live
Run code in the Playground, scaffold a contract, demo an agent, or preview a token mint, no setup.
MCP Server
Connect AI assistants like Claude and Cursor to Hedera with the Model Context Protocol server.
Network Explorers
Visualize accounts, tokens, transactions, and contracts on Hedera.
JSON-RPC Relay
EVM-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.
Solo
Deploy and operate a Hiero/Hedera network locally with Kubernetes, perfect for development and testing.
